The Skull In The Limestone<\/p>\n
The cave goes deep.<\/p>\n
Gough’s Cave in Cheddar Gorge, Somerset, cuts about 115 meters into the limestone of the Mendip Hills before reaching its innermost chambers.<\/p>\n
The walls are cool and damp.<\/p>\n
The temperature barely changes year-round.<\/p>\n
The darkness is absolute once you leave the light behind.<\/p>\n
In 1903, during excavations inside this cave, a workman’s tool struck something that was neither limestone nor sediment.<\/p>\n
Bones emerged from the earth.<\/p>\n
Human bones.<\/p>\n
A skull, portions of a skeleton \u2014 and then something more: the almost complete remains of a person who had died in this cave roughly ten millennia before the workmen arrived.<\/p>\n
The skeleton was given a name that stuck: Cheddar Man.<\/p>\n
Not for any personal characteristic, not for anything the bones revealed about the person who had been buried or had died here, but simply because the cave was in Cheddar, and the cheese came from Cheddar, and the name was apt in the way that simple geographical labels can be.<\/p>\n
The man from Cheddar.<\/p>\n
For more than a century, scientists studied those bones.<\/p>\n
They measured the skull with calipers.<\/p>\n
They examined the teeth, which were surprisingly good for someone who had died around the age of twenty-three to twenty-six.<\/p>\n
They analyzed the skeleton’s proportions and concluded that this person had stood about five feet five inches tall, had been reasonably well-nourished, and had lived sometime around 9,000 years before the common era \u2014 roughly 10,000 years before the moment you are reading this.<\/p>\n
They made assumptions about what he looked like.<\/p>\n
<\/p>\n
Those assumptions, as it turned out, were largely wrong.<\/p>\n
In February 2018, researchers at University College London and the Natural History Museum in London announced the results of a full genome sequencing of Cheddar Man’s DNA \u2014 the first complete genome sequenced from the oldest near-complete skeleton found in Britain.<\/p>\n
What they found was striking enough that it reached every major news outlet in the world within twenty-four hours.<\/p>\n
Cheddar Man had dark to black skin pigmentation.<\/p>\n
He had blue eyes.<\/p>\n
He had dark, curly hair.<\/p>\n
The combination was the opposite of what most people assumed when they imagined someone called “the first Briton.” The expectation \u2014 tacit, unexamined, embedded in decades of museum displays and popular reconstructions \u2014 had been fair skin.<\/p>\n
What the DNA said was something entirely different.<\/p>\n
The finding was not simply a curiosity about one individual.<\/p>\n
It was a data point in a much larger story that ancient DNA science has been assembling piece by piece over the past two decades: the story of who the Europeans of the deep past actually were, where they came from, and why they looked nothing like the people who later came to occupy the same territory.<\/p>\n
That story begins in a limestone cave.<\/p>\n
It ends somewhere larger.<\/p>\n
Gough’s Cave And What Lives In The Dark<\/p>\n
Cheddar Gorge is one of the more dramatic landscapes in the otherwise gentle English county of Somerset.<\/p>\n
<\/p>\n
The gorge cuts through the Mendip Hills, a plateau of carboniferous limestone that was formed by ancient shallow seas, and the walls on either side of the road through the gorge rise to heights of more than 130 meters.<\/p>\n
The rock is grey-white and sculpted by water \u2014 limestone is soluble, and the slightly acidic rain that falls over the Mendips has been dissolving and reshaping it for millions of years.<\/p>\n
Inside the limestone, water creates caves.<\/p>\n
The cave system that includes Gough’s Cave has been forming for somewhere between two and four million years, shaped by underground rivers that once flowed through the rock and have since largely dried up or diverted.<\/p>\n
The chambers that remain are formations of extraordinary beauty: stalactites hanging from the ceiling, stalagmites rising from the floor, curtains of flowstone draped across the walls.<\/p>\n
<\/p>\n
The limestone that was once deposited by tropical seas has been sculpted by deep time into something that looks like the work of an extraordinary artist.<\/p>\n
The cave has been open to the public for more than a century \u2014 a tourist attraction that brings visitors through the dimly lit passages to see the formations.<\/p>\n
But beneath the tourist infrastructure, the deeper archaeology of the site tells a story that goes back far further than any recorded human occupation of Britain.<\/p>\n
The cave attracted human visitors and inhabitants intermittently across thousands of years before recorded history.<\/p>\n
The earliest human presence at the site dates to approximately 14,700 years ago \u2014 the Paleolithic period, the Old Stone Age, when anatomically modern humans were spreading across Europe as the great glaciers that had covered much of the continent were beginning to retreat.<\/p>\n
<\/p>\n
These earliest visitors to Gough’s Cave left evidence of an activity that is deeply disturbing to modern sensibilities: they were processing and consuming human bodies.<\/p>\n
The bones found in the site from this early period show clear evidence of defleshing \u2014 cut marks made by stone tools across the bones \u2014 and cracking to extract marrow.<\/p>\n
Some of the bones had been worked into tools.<\/p>\n
What this represents \u2014 ritual cannibalism, funerary defleshing, something else entirely \u2014 is a question that researchers have debated without fully resolving.<\/p>\n
After this early occupation, there is a gap in the human record at Gough’s Cave \u2014 a period when the cave was not occupied, or when any occupation left no recoverable trace.<\/p>\n
And then, roughly 10,000 years ago, the person now known as Cheddar Man appears in the record.<\/p>\n
<\/p>\n
A Different Kind Of Occupation<\/p>\n
The Mesolithic period \u2014 the Middle Stone Age, dated roughly from about 10,000 BCE to about 4,000 BCE in Britain \u2014 was a time of profound environmental transition.<\/p>\n
The great ice sheets that had covered northern Europe during the Last Glacial Maximum were retreating rapidly.<\/p>\n
Sea levels were rising as the meltwater returned to the oceans.<\/p>\n
The landmass of Britain was changing shape.<\/p>\n
At the start of the Mesolithic, Britain was not yet an island.<\/p>\n
<\/p>\n
It was connected to continental Europe by a wide plain of land that has since been given the name Doggerland \u2014 a name derived from the Dogger Bank in the North Sea, which was once part of this landscape.<\/p>\n
Doggerland encompassed what is now the southern North Sea and the English Channel, stretching from the current British coastline to what is now Denmark and the Netherlands.<\/p>\n
This was inhabited land.<\/p>\n
Archaeological evidence recovered from the bottom of the North Sea \u2014 brought up in fishing nets, found during oil exploration, surveyed by underwater archaeologists \u2014 indicates that Doggerland was a rich and productive landscape.<\/p>\n
Rivers crossed it.<\/p>\n
<\/p>\n
Lakes and marshes provided resources.<\/p>\n
Communities of hunter-gatherers lived on it for thousands of years.<\/p>\n
As the ice sheets melted, sea levels rose.<\/p>\n
Doggerland shrank.<\/p>\n
The rising waters of the North Atlantic and the rising waters of the North Sea slowly encircled what would become Britain, isolating it from the European mainland in a process that was complete by roughly 6,000 to 8,000 years ago.<\/p>\n
The communities that lived in Doggerland moved as the water rose \u2014 some onto higher ground that became the British Isles, some onto what became the mainland of northern Europe.<\/p>\n
<\/p>\n
The Mesolithic people who moved into Britain as the ice retreated were not the same as the people who had lived there before \u2014 or rather, the populations that had survived in the European south during the glacial maximum were moving north as the ice permitted.<\/p>\n
They were hunter-gatherers with a highly sophisticated toolkit: small blades called microliths that could be hafted into arrows and spears, equipment for fishing and fowling, the full range of knowledge required to exploit the productive environments of the postglacial north.<\/p>\n
Among these people, or among those who came slightly later in the Mesolithic occupation of Britain, was the individual who would eventually be found in Gough’s Cave and named Cheddar Man.<\/p>\n
The Discovery Of 1903<\/p>\n
<\/p>\n
The formal excavation that led to the discovery of Cheddar Man’s remains was conducted in 1903 by a team working under Richard Cox Gough, the owner of the cave who had been developing it as a tourist attraction for the previous decade.<\/p>\n
The human skeleton was found during this excavation work, buried \u2014 or naturally covered \u2014 in sediment in one of the inner chambers of the cave.<\/p>\n
The bones were not scattered or disturbed in the way that the earlier Paleolithic cannibalistic deposits had been.<\/p>\n
This was, or appeared to be, a more deliberate or natural burial: one individual, more or less in place, covered by the accumulating sediment of millennia.<\/p>\n
The skeleton was not complete \u2014 some bones were missing, and others were fragmented \u2014 but it was substantial enough to allow reconstruction of much of the body.<\/p>\n
<\/p>\n
The skull was largely intact.<\/p>\n
The limb bones were present.<\/p>\n
The overall picture was of a young man in reasonably good health at the time of his death.<\/p>\n
What was immediately apparent was the great age of the remains.<\/p>\n
The bones were in a state of preservation consistent with great antiquity, and their depth in the sediment suggested they had been buried for a very long time.<\/p>\n
Early dating attempts using the tools available in the early twentieth century produced estimates that placed the burial in the distant past, though the precision of those early methods was limited.<\/p>\n
<\/p>\n
The skeleton was transported to the Natural History Museum in London, where it has been housed and studied for more than a century.<\/p>\n
Its physical characteristics were analyzed repeatedly as methods improved.<\/p>\n
By the mid-twentieth century, radiocarbon dating \u2014 developed in the late 1940s \u2014 allowed researchers to get a more precise date: the bones were approximately 9,000 radiocarbon years old, which calibrates to roughly 10,000 calendar years before the present.<\/p>\n
This placed Cheddar Man at the very beginning of Britain’s Mesolithic period, among the first people to establish what the DigVentures team called “continuous habitation” of the island after the most recent glacial period.<\/p>\n
He was not the first modern human to reach Britain \u2014 there is evidence of earlier Paleolithic presence \u2014 but he represented the population from which continuous British occupation derives.<\/p>\n
<\/p>\n
That distinction matters.<\/p>\n
Previous populations had reached Britain, but they did not survive long enough to establish a permanent presence.<\/p>\n
Cheddar Man’s population was the one that stayed.<\/p>\n
What The Bones Said Before The DNA<\/p>\n
For decades, the story of Cheddar Man was told primarily through osteology \u2014 the study of bones.<\/p>\n
Before ancient DNA analysis became possible, everything that researchers knew or inferred about him came from the physical skeleton and its archaeological context.<\/p>\n
Some of what the bones revealed was straightforward.<\/p>\n
<\/p>\n
He was male, based on the morphological characteristics of the skeleton.<\/p>\n
He was young \u2014 probably in his early to mid twenties when he died, based on the development of his teeth and the fusion of his growth plates.<\/p>\n
He was of roughly average height for the period, around 166 centimeters (about five feet five inches).<\/p>\n
His teeth were in good condition, with little evidence of tooth decay or significant wear \u2014 consistent with a diet that was high in protein and low in refined carbohydrates.<\/p>\n
His skull showed certain features that researchers used to characterize his morphology: a relatively long skull, prominent brow ridges, a face that was consistent with what was being found at other Mesolithic sites across Europe.<\/p>\n
<\/p>\n
He had what some researchers described as a unique facial structure \u2014 somewhat different from both the earlier Paleolithic populations and the later Neolithic populations that would replace the Mesolithic hunter-gatherers across Europe.<\/p>\n
There was also evidence of something more ambiguous: damage to his skull.<\/p>\n
Specifically, there were holes in the skull that could be interpreted as evidence of violence \u2014 a blow to the head, perhaps, or some other form of physical trauma.<\/p>\n
Or they could have been caused by the natural processes of decomposition and burial, or by the damage inflicted by excavation in 1903.<\/p>\n
The question of how Cheddar Man died has never been definitively answered.<\/p>\n
<\/p>\n
He appears to have been buried alone.<\/p>\n
Most Mesolithic burials in Britain and Europe from this period were communal or involved multiple individuals, often buried together or in close proximity.<\/p>\n
A single, isolated burial was somewhat unusual.<\/p>\n
Whether this reflected something particular about this individual \u2014 his status, the circumstances of his death, the specific practices of his community \u2014 or whether it was simply the result of chance and preservation is not established.<\/p>\n
And until 2018, one of the most fundamental questions about him \u2014 what did he look like? \u2014 could not be answered precisely.<\/p>\n
<\/p>\n
Reconstructions had been made over the decades, based on osteological analysis and general assumptions about what people of the period looked like.<\/p>\n
These reconstructions had given him light or medium skin pigmentation.<\/p>\n
The DNA analysis would change that.<\/p>\n
The Ancient DNA Revolution<\/p>\n
To understand what the 2018 Cheddar Man study accomplished, it is necessary to understand what ancient DNA science is and what it has done to our knowledge of the human past.<\/p>\n
The study of ancient DNA \u2014 genetic material recovered from archaeological specimens \u2014 has been one of the most transformative scientific developments in archaeology and human paleontology in the past quarter century.<\/p>\n
It has fundamentally revised our understanding of who populated the world in the deep past, where people came from, how populations moved and mixed, and what the people of the distant past actually looked like.<\/p>\n
<\/p>\n
The first successful recovery of ancient DNA from human remains was announced in 1985, when researchers extracted a small amount of genetic material from an ancient Egyptian mummy.<\/p>\n
But this early work was limited \u2014 the amounts of DNA were tiny, the sequences were short, and the risk of contamination from modern human DNA was enormous.<\/p>\n
For years, ancient DNA research proceeded slowly, hampered by these technical limitations.<\/p>\n
The revolution began in the mid-2000s and accelerated dramatically in the 2010s, driven by two related technological developments.<\/p>\n
The first was the development of next-generation sequencing technology, which could sequence millions of DNA fragments simultaneously rather than laboriously reading sequences one at a time.<\/p>\n
This increased both the speed and the power of DNA analysis by orders of magnitude, making it possible to recover and analyze genetic material from samples that would have been completely intractable using earlier methods.<\/p>\n
<\/p>\n
The second was the development of specific techniques for working with highly degraded ancient DNA \u2014 the kind of severely fragmented, chemically damaged material that is all that survives in most archaeological specimens.<\/p>\n
Ancient DNA is not preserved intact; it is broken into short fragments by the chemical processes of decomposition, and those fragments carry specific types of damage \u2014 particularly the deamination of cytosine molecules \u2014 that distinguish genuine ancient sequences from modern contamination.<\/p>\n
Learning to identify and filter for these damage patterns made ancient DNA analysis far more reliable.<\/p>\n
By the mid-2010s, researchers could routinely sequence complete or near-complete genomes from ancient skeletal material under favorable preservation conditions.<\/p>\n
The petrous bone \u2014 the densest bone in the human body, located at the base of the skull as part of the temporal bone \u2014 had been identified as the most reliable source of ancient DNA, because its density protects the genetic material from the microbial and chemical degradation that destroys DNA in other skeletal elements.<\/p>\n
<\/p>\n
Cheddar Man’s petrous bone was intact.<\/p>\n
The cool, stable limestone environment of Gough’s Cave had provided exceptional preservation conditions.<\/p>\n
And the UCL\/NHM team that approached the project in 2017 had access to the most sophisticated ancient DNA analysis methods available.<\/p>\n
They drilled a two-millimeter hole into the skull to extract bone powder from the inner ear region.<\/p>\n
The amount of material they needed was tiny \u2014 just a few milligrams of bone.<\/p>\n
The DNA within that powder was the result of ten thousand years of preservation, and it was, by the standards of ancient DNA work, unusually well-preserved.<\/p>\n
<\/p>\n
What The Genome Contains<\/p>\n
Before turning to what the analysis found, it is worth explaining what a genome is and what it can tell scientists about appearance and ancestry.<\/p>\n
The human genome is the complete set of genetic instructions encoded in the DNA of a cell.<\/p>\n
In the nucleus of most human cells, this information is organized into 23 pairs of chromosomes \u2014 long molecules of DNA, packaged by proteins, that carry the instructions for building and operating a human body.<\/p>\n
The genome contains approximately three billion base pairs of DNA \u2014 three billion positions, each occupied by one of four chemical bases (adenine, thymine, guanine, cytosine), in sequences that encode the instructions for every aspect of human biology.<\/p>\n
<\/p>\n
Within those three billion positions, the regions that determine physical characteristics \u2014 skin pigmentation, eye color, hair texture, height, and thousands of other traits \u2014 have been increasingly mapped by human genomics research over the past two decades.<\/p>\n
Large-scale studies of thousands of living people, comparing their genomes to their observable characteristics, have identified specific genetic variants \u2014 specific positions in the genome where the base occupying that position correlates with a particular characteristic.<\/p>\n
Skin pigmentation, for example, is determined by the production of melanin \u2014 a pigment produced by cells called melanocytes in the skin.<\/p>\n
The amount and type of melanin produced is controlled by genes that regulate melanocyte activity.<\/p>\n
Dozens of genetic variants across multiple genes contribute to skin color, and modern genomic analysis can examine all of them in a genome to produce a probabilistic assessment of the likely skin pigmentation of an individual.<\/p>\n
<\/p>\n
The assessment is probabilistic, not deterministic.<\/p>\n
The genetic variants associated with skin color are statistical predictors \u2014 variants that are more common in people with darker or lighter skin, but not exclusively present in one group or the other.<\/p>\n
A pigmentation prediction based on genetic variants is a best estimate, not a certainty, and the researchers involved in the Cheddar Man study were careful to emphasize this point.<\/p>\n
Their assessment that Cheddar Man had dark to black skin was based on the combination of genetic variants in his genome compared to the patterns established in living populations.<\/p>\n
<\/p>\n
It was a strong inference, not an absolute certainty.<\/p>\n
Eye color and hair color and texture operate similarly \u2014 determined by multiple genetic variants that can be analyzed from a genome to produce probabilistic predictions.<\/p>\n
Beyond physical characteristics, the genome carries information about ancestry.<\/p>\n
Specific patterns of genetic variation \u2014 specific combinations of variants found at specific frequencies \u2014 are characteristic of different population groups with different histories.<\/p>\n
By comparing an ancient genome to reference databases of modern and ancient genomes, researchers can determine which population group the ancient individual is most closely related to, and what that relationship implies about migration and population history.<\/p>\n
Opening The Genome<\/p>\n
<\/p>\n
The analysis of Cheddar Man’s genome in 2017 and early 2018 \u2014 conducted primarily by Professor Mark Thomas and Dr.<\/p>\n
Yoan Diekmann at UCL’s Genetics, Evolution & Environment department, in collaboration with the Natural History Museum team including Selina Brace and Tom Booth \u2014 produced a comprehensive picture of the genome of a ten-thousand-year-old British hunter-gatherer.<\/p>\n
The researchers extracted the DNA, identified and filtered for the characteristic damage patterns of ancient DNA to eliminate modern contamination, and assembled the fragmentary ancient sequences into a coherent genome.<\/p>\n
The result was the most complete genetic portrait of a Mesolithic British individual ever obtained.<\/p>\n
<\/p>\n
Several major findings emerged from the analysis.<\/p>\n
The most publicized was the pigmentation assessment: the combination of genetic variants in Cheddar Man’s genome predicted dark to black skin pigmentation.<\/p>\n
The specific variants associated with reduced melanin production \u2014 the variants that are common in people with light skin \u2014 were largely absent.<\/p>\n
The variants associated with higher melanin production \u2014 more commonly found in people with darker skin \u2014 were present.<\/p>\n
Alongside this, the analysis predicted blue eye color.<\/p>\n
<\/p>\n
The genetic basis for blue eyes in Europeans is relatively well-understood, centered primarily on variants in and around a gene called HERC2\/OCA2.<\/p>\n
These variants, which are common across European populations today, were present in Cheddar Man’s genome.<\/p>\n
The combination \u2014 dark skin with blue eyes \u2014 was striking to the point of seeming paradoxical to modern observers.<\/p>\n
Contemporary Europeans with blue eyes are almost universally light-skinned.<\/p>\n
The coexistence of blue eyes and dark skin in a single individual seems unusual from the perspective of contemporary European populations.<\/p>\n
But as the researchers explained, this combination was not unusual for Mesolithic Europeans.<\/p>\n
<\/p>\n
Multiple other ancient individuals from the same period, found at sites across Europe \u2014 in Spain, Hungary, Luxembourg, and elsewhere \u2014 had shown the same combination in earlier ancient DNA analyses.<\/p>\n
Cheddar Man was not an outlier; he was representative of his time and of his population.<\/p>\n
The reason this combination existed \u2014 and why it looks strange to contemporary eyes \u2014 is a story about when light skin pigmentation evolved in Europeans, and the answer to that story is different from what had been assumed.<\/p>\n
Why Skin Color Changed: The Key Insight<\/p>\n
For many decades before the ancient DNA revolution, the prevailing assumption among scientists was that modern humans who entered Europe from Africa roughly 40,000 to 45,000 years ago had relatively quickly developed lighter skin pigmentation as an adaptation to the lower ultraviolet radiation environment of northern latitudes.<\/p>\n
<\/p>\n
The reasoning seemed straightforward.<\/p>\n
Dark skin pigmentation is an adaptation to high UV environments \u2014 melanin protects against DNA damage and the destruction of folate that excess UV radiation causes.<\/p>\n
In the high-UV environments of the tropics and subtropics, where modern humans evolved, dark pigmentation is advantageous.<\/p>\n
But in the lower-UV environments of northern Europe, where UV is weaker and sometimes too weak to produce adequate vitamin D through skin synthesis, the need for UV protection diminishes, and the need for vitamin D synthesis becomes more important.<\/p>\n
Lighter skin \u2014 which allows more UV penetration and thus more vitamin D synthesis \u2014 becomes advantageous.<\/p>\n
<\/p>\n
The assumption, in its simplest form, was: enter Europe, lose the dark skin quickly, because the selective pressure for lighter skin would be immediate and strong.<\/p>\n
What the ancient DNA evidence has consistently shown is that this happened much more slowly than anyone expected.<\/p>\n
Cheddar Man lived roughly 10,000 years after the initial entry of modern humans into Europe.<\/p>\n
His population \u2014 the Western Hunter-Gatherers, as researchers have named them \u2014 had been in Europe for approximately ten to fifteen thousand years before the time Cheddar Man was alive.<\/p>\n
And yet the genetic analysis of Cheddar Man and his contemporaries shows that they retained dark pigmentation.<\/p>\n
<\/p>\n
Why?<\/p>\n
The answer likely involves multiple factors.<\/p>\n
First, the selection pressure for lighter skin, while real, may have been weaker than assumed \u2014 because the hunter-gatherer diet of this period was rich in vitamin D from animal sources, particularly fish and organ meats, reducing the dependence on skin synthesis.<\/p>\n
Second, the time required for natural selection to shift the frequency of pigmentation variants across an entire population is not trivial \u2014 it requires many generations of differential survival and reproduction, and even relatively strong selection pressure takes thousands of years to substantially change allele frequencies.<\/p>\n
Third \u2014 and this is a crucial point from the population genetics evidence \u2014 the actual genetic change in European skin pigmentation was not simply a gradual evolution of the people who were already there.<\/p>\n
<\/p>\n
It was substantially driven by the arrival of new populations carrying different pigmentation genetics.<\/p>\n
The farmers who began arriving in Europe from Anatolia (the region that is now Turkey) approximately 8,000 to 10,000 years ago \u2014 the Neolithic transition \u2014 carried genes for lighter pigmentation that were then distributed across Europe as the farming population expanded.<\/p>\n
And the steppe pastoralists who arrived later, around 5,000 years ago, from the Pontic-Caspian steppe north of the Black Sea, brought additional genetic variants.<\/p>\n
The light skin of modern Europeans is largely the result of these population turnovers and mixtures, not of selection acting on a single continuous European population.<\/p>\n
<\/p>\n
The Western Hunter-Gatherers like Cheddar Man \u2014 the Mesolithic people who inhabited Europe before the farmers arrived \u2014 were, as far as the ancient DNA evidence shows, predominantly dark-skinned.<\/p>\n
They left their mark on modern Europeans: approximately ten percent of the ancestry of modern white British people can be traced to the Western Hunter-Gatherer population to which Cheddar Man belonged.<\/p>\n
But they were replaced and diluted, not gradually lightened.<\/p>\n
The Western Hunter-Gatherers: Who They Were<\/p>\n
The group to which Cheddar Man belonged \u2014 the Western Hunter-Gatherers, abbreviated WHG in the ancient DNA literature \u2014 is now one of the best-characterized ancient human populations in the genetic record.<\/p>\n
The term Western Hunter-Gatherer refers to the population of Mesolithic hunter-gatherers who inhabited western and central Europe in the period roughly from 14,000 to 5,000 years before the present \u2014 from the end of the last Ice Age to the arrival of Neolithic farmers.<\/p>\n
<\/p>\n
They were not a single unified culture or political entity, but they show a coherent pattern of genetic similarity that indicates shared ancestry and limited interbreeding with other populations during this period.<\/p>\n
The WHG population is genetically most closely related to an even older European population called the Villabruna cluster, which includes individuals from Italy and the broader Mediterranean region dating to roughly 14,000 years ago.<\/p>\n
Before the WHG, earlier Paleolithic Europeans \u2014 called Ancient European Hunter-Gatherers \u2014 were largely replaced during the Last Glacial Maximum; the WHG represent the population that re-expanded across Europe as the ice retreated.<\/p>\n
Other ancient individuals assigned to the Western Hunter-Gatherer group include individuals found at sites in Spain (the La Bra\u00f1a site in Le\u00f3n, dating to approximately 7,000 years ago), Hungary, Luxembourg, and other European locations.<\/p>\n
<\/p>\n
The analysis of these individuals \u2014 including, in some cases, before the Cheddar Man study \u2014 had already established that WHG individuals tended to have dark skin, blue or green eyes, and dark hair.<\/p>\n
Cheddar Man was consistent with this pattern.<\/p>\n
The WHG were not physiologically exotic.<\/p>\n
They were anatomically modern humans, with the same cognitive capabilities and behavioral sophistication as any contemporary human population.<\/p>\n
They were skilled hunters and gatherers who understood the ecology of postglacial Europe in extraordinary detail \u2014 they had to, to survive and thrive in an environment that was changing rapidly as the ice retreated and new ecosystems established themselves.<\/p>\n
They built no permanent monuments.<\/p>\n
<\/p>\n
They left no pottery, which had not yet been developed.<\/p>\n
They were not farmers and did not raise livestock.<\/p>\n
Their subsistence was based entirely on what the landscape could provide: red deer, wild boar, aurochs (the ancestor of modern cattle), beaver, otter, fish, shellfish, birds, nuts, berries, roots, and all the other products of the postglacial European environment.<\/p>\n
They were highly mobile \u2014 following the seasonal movements of game, moving between resources as they became available.<\/p>\n
This mobility left relatively few traces in the archaeological record: temporary campsites, scattered tools, occasional burials.<\/p>\n
<\/p>\n
The Mesolithic leaves a lighter footprint than almost any other period of human prehistory precisely because the people of the Mesolithic were not building the permanent structures or mass-producing the durable goods that leave obvious archaeological traces.<\/p>\n
The Facial Reconstruction<\/p>\n
Alongside the genetic analysis, the 2018 Cheddar Man project included the production of a facial reconstruction \u2014 a physical model of what the man might have looked like in life.<\/p>\n
This reconstruction was created by Dutch paleo-artists Adrie and Alfons Kennis, who are specialists in the production of scientifically informed representations of ancient humans.<\/p>\n
The brothers have produced reconstructions of numerous ancient and prehistoric individuals, and their work is known for its combination of scientific rigor and artistic skill.<\/p>\n
The reconstruction process began with a high-resolution three-dimensional scan of the skull.<\/p>\n
<\/p>\n
This scan was used to produce a 3D printed replica of the skull, which became the foundation for the facial reconstruction.<\/p>\n
The soft tissue reconstruction \u2014 the muscles, fat pads, skin, and other soft tissues that flesh out a face over a skull \u2014 was built up layer by layer over this 3D printed base, using established forensic guidelines about the typical relationship between skull structure and facial appearance.<\/p>\n
The specific characteristics of the reconstruction \u2014 the dark skin, the blue eyes, the dark curly hair \u2014 were derived from the genetic analysis.<\/p>\n
The Kennis brothers worked in close collaboration with the DNA research team, translating the probabilistic genetic predictions into specific visual features.<\/p>\n
<\/p>\n
The result was striking: a young man with a dark complexion, striking blue eyes, curly dark hair, and facial features shaped by the morphology of the underlying skull.<\/p>\n
The reconstruction looked nothing like the earlier models of Cheddar Man that had given him light skin.<\/p>\n
When the reconstruction was unveiled in February 2018 as part of a Channel 4 documentary and a Natural History Museum exhibition, the response was substantial.<\/p>\n
The image circulated widely on social media and in news coverage, generating the kind of engagement that few scientific discoveries produce.<\/p>\n
Part of the response was simple surprise \u2014 the face was unexpected, the blue-eyed dark-skinned combination was visually distinctive, and the connection of this ancient individual to modern British identity was obvious.<\/p>\n
<\/p>\n
But part of the response was more politically charged: the finding had implications for narratives about race and identity in Britain that some people found uncomfortable and others found illuminating.<\/p>\n
The Political Context And Its Complexity<\/p>\n
The announcement of Cheddar Man’s genetic characteristics arrived in February 2018 at a particular moment in British political culture.<\/p>\n
Brexit had been voted for in 2016.<\/p>\n
Immigration was a contentious political issue.<\/p>\n
Questions about British identity, what it meant to be British, and the historical depth of different communities’ connections to British soil were live in public discourse in a way they had not been for decades.<\/p>\n
Into this environment, the finding that the oldest near-complete skeleton in England had dark skin entered like a stone into a pool.<\/p>\n
<\/p>\n
The response covered a wide spectrum.<\/p>\n
Many people found the finding fascinating on purely scientific grounds \u2014 a genuine window into the deep past, a challenge to assumptions about human prehistory.<\/p>\n
Many others found the finding illuminating specifically because of its implications for the political discourse around race and belonging: if the “first Briton” had dark skin, what did that say about the idea that racial or ethnic identity is somehow inherent to British geography?<\/p>\n
A smaller number of people responded with hostility, interpreting the finding as a politically motivated distortion of history, or questioning the reliability of the genetic methodology, or arguing that the finding was being weaponized for ideological purposes.<\/p>\n
<\/p>\n
The researchers involved in the project were clear that their goal was scientific understanding, not political intervention.<\/p>\n
They emphasized that the finding was not about contemporary politics but about the genuine characteristics of a real person who lived ten thousand years ago.<\/p>\n
They also acknowledged that the finding was striking and that its implications for popular assumptions were real.<\/p>\n
Bio-archaeologist Tom Booth’s response to the finding was characteristic of the researchers’ approach: Cheddar Man was one person, but he was “also indicative of the population of Europe at the time.<\/p>\n
They had dark skin and most of them had pale coloured eyes, either blue or green, and dark brown hair.”<\/p>\n
<\/p>\n
The population-level finding \u2014 that Western Hunter-Gatherer Europeans generally had dark skin with light eyes \u2014 was actually not new.<\/p>\n
Earlier ancient DNA analyses of WHG individuals in Spain, Hungary, and elsewhere had already shown this pattern.<\/p>\n
What made the Cheddar Man study different was the combination of factors: the age and completeness of the specimen, the quality of the genetic analysis, and the production of the physical facial reconstruction that made the finding visual and immediate rather than abstract.<\/p>\n
Cheddar Man As The Oldest Complete British Genome<\/p>\n
<\/p>\n
One specific designation that the 2018 study established deserves emphasis: Cheddar Man represents the oldest British individual to have had his whole genome sequenced.<\/p>\n
This is not a trivial distinction.<\/p>\n
Whole-genome sequencing \u2014 reconstructing the full sequence of all three billion base pairs in a genome, rather than examining only specific targeted positions \u2014 provides a vastly more powerful analytical tool than partial genetic analysis.<\/p>\n
With a whole genome, researchers can examine every position in the DNA simultaneously, rather than just the positions they had previously identified as informative.<\/p>\n
They can look at the full spectrum of genetic variants, compare them to both ancient and modern reference populations with maximum statistical power, and make much more precise inferences about ancestry, pigmentation, and other characteristics.<\/p>\n
<\/p>\n
Earlier Mesolithic specimens from Britain had yielded partial genetic information \u2014 enough to say something about their ancestry but not enough to characterize them fully.<\/p>\n
Cheddar Man’s exceptional preservation provided the material for the first whole-genome sequencing of a Mesolithic Briton, setting a new standard for what could be known about the deep human past of the British Isles.<\/p>\n
Professor Chris Stringer of the Natural History Museum, who had studied Cheddar Man for more than forty years and had first excavated at Gough’s Cave thirty years before the 2018 study, put it directly: “I first studied ‘Cheddar Man’ more than 40 years ago, but could never have believed that we would one day have his whole genome \u2014 the oldest British one to date!”<\/p>\n
The whole-genome data provided not just the pigmentation characteristics that attracted the most media attention but a full picture of Cheddar Man’s genetic ancestry \u2014 his relationship to other ancient European populations, to populations outside Europe, and to modern British people.<\/p>\n
<\/p>\n
What The Ancestry Analysis Found<\/p>\n
Beyond the physical characteristics, the genome analysis placed Cheddar Man firmly within the Western Hunter-Gatherer population and illuminated his specific position in the broader human genealogy.<\/p>\n
The analysis showed that Cheddar Man’s ancestors had come into Europe at the end of the Last Glacial Maximum \u2014 roughly 14,000 to 11,000 years ago \u2014 as part of the recolonization of northern and western Europe after the ice retreated.<\/p>\n
The specific genetic signature of his population is most closely related to the population that appears in southern Europe and the Balkans around the end of the last Ice Age, suggesting that the ancestors of Britain’s Mesolithic people came north through the European continent as the ice opened habitable territory.<\/p>\n
<\/p>\n
The connection to other WHG individuals from across Europe \u2014 in Spain, Hungary, and Luxembourg, as noted by Professor Thomas \u2014 confirmed that Cheddar Man’s population was part of a broad meta-population that had spread across western and central Europe during the Mesolithic.<\/p>\n
This was not a genetically isolated British population; it was the western extension of a continental-scale meta-population of hunter-gatherers who shared common ancestry.<\/p>\n
The analysis also showed what Cheddar Man’s population was not related to: the Anatolian farmers who would later bring agriculture to Europe, and the steppe pastoralists who would come still later.<\/p>\n
These later populations \u2014 whose arrival would transform European genetics and, with them, European skin pigmentation \u2014 were absent from Cheddar Man’s genome.<\/p>\n
He predated both population turnovers.<\/p>\n
<\/p>\n
This absence is itself historically informative.<\/p>\n
It confirms that at the time Cheddar Man was alive \u2014 roughly 10,000 years ago \u2014 Britain had not yet been reached by the Neolithic farmers from Anatolia.<\/p>\n
The farming transition in Britain began around 6,000 years ago, meaning that Cheddar Man lived approximately 4,000 years before the transformation of British society that would eventually, through the mixing of populations, produce the ancestors of modern British people.<\/p>\n
The Connection To Living Britons<\/p>\n
<\/p>\n
One of the more fascinating aspects of the Cheddar Man research was the investigation of whether any living people in Britain today carry DNA that can be traced to the Western Hunter-Gatherer population to which he belonged.<\/p>\n
This had been investigated earlier, in a 1997 study by Bryan Sykes and his Oxford colleagues, before whole-genome sequencing was available.<\/p>\n
That study had compared mitochondrial DNA \u2014 the small circular genome found in the mitochondria rather than the nucleus, which is inherited exclusively through the maternal line \u2014 from Cheddar Man with mitochondrial DNA from living residents of the Cheddar area.<\/p>\n
The study found a schoolteacher named Adrian Targett who shared the same rare mitochondrial haplogroup as Cheddar Man, suggesting a possible maternal-line connection across ten millennia.<\/p>\n
<\/p>\n
The 2018 whole-genome analysis provided a much more powerful and nuanced picture.<\/p>\n
While the specific individual-to-individual comparison of the 1997 study had limited interpretive power, the broader finding from the whole-genome analysis was that approximately ten percent of the ancestry of modern white British people can be traced to the Western Hunter-Gatherer population to which Cheddar Man belonged.<\/p>\n
This figure \u2014 ten percent \u2014 is striking because it implies that about ninety percent of modern British ancestry comes from the later populations: primarily the Neolithic Anatolian farmers and the Bronze Age steppe pastoralists who arrived later.<\/p>\n
The genetic continuity of the Western Hunter-Gatherers in modern British people is real but minority: the WHG ancestry is present, but diluted by the much larger genetic contribution of the subsequent population movements.<\/p>\n
<\/p>\n
This finding has implications for how we think about the relationship between ancient and modern populations.<\/p>\n
When Cheddar Man is described as one of the “first Britons,” that is accurate in the sense that his population was among the first to establish continuous habitation of what would become Britain.<\/p>\n
But the relationship between his population and modern British people is not primarily one of direct descent.<\/p>\n
It is more like the relationship between a small original shareholder in a company and the much larger number of later investors \u2014 the original stake is present, but diluted.<\/p>\n
The Lactose Question: A Window Into Diet And Evolution<\/p>\n
<\/p>\n
One of the genetics findings from the Cheddar Man analysis that received less attention than the pigmentation findings but is equally significant is the question of lactose tolerance.<\/p>\n
Cheddar Man, the analysis showed, was lactose intolerant.<\/p>\n
Specifically, the variant in the LCT gene that enables the continued production of lactase \u2014 the enzyme that digests lactose, the sugar in milk \u2014 into adulthood was absent from his genome.<\/p>\n
He had the ancestral form of the gene, which causes lactase production to decline after childhood, as it does in most mammals.<\/p>\n
This finding is significant for multiple reasons.<\/p>\n
<\/p>\n
First, it is consistent with what we know about the timeline of lactose tolerance evolution in Europe.<\/p>\n
The genetic variant that confers adult lactase persistence \u2014 known as LP \u2014 spread through European populations during the Bronze Age, roughly 3,000 to 4,000 years ago, well after Cheddar Man’s time.<\/p>\n
Its current high frequency in northern European populations is the result of strong natural selection during that period, in communities that depended heavily on domesticated cattle for their food supply and whose survival and reproductive success was substantially enhanced by the ability to digest milk throughout life.<\/p>\n
In the Mesolithic, when dairy farming did not exist, there was no selection pressure for lactase persistence.<\/p>\n
<\/p>\n
The wild animals that hunter-gatherers hunted were not domesticated and were not available for milking.<\/p>\n
Cheddar Man and his contemporaries had no access to dairy products as adults and no selective reason to maintain lactase production after childhood.<\/p>\n
Second, the lactose intolerance finding is a reminder that the Mesolithic world was profoundly different from the modern world in ways that go far beyond technology.<\/p>\n
The physiological adaptation to dairy consumption that is now widespread in northern European populations is a very recent evolutionary development, a response to a specific subsistence pattern that was introduced by Neolithic farmers and then expanded by Bronze Age pastoralists.<\/p>\n
Cheddar Man’s body was adapted to his world \u2014 the world of the Mesolithic hunter-gatherer \u2014 in ways that would have made him physically different from his descendants not just in appearance but in physiology.<\/p>\n
<\/p>\n
The Limits Of What DNA Can Tell Us<\/p>\n
The Cheddar Man study was careful to acknowledge the limits of what ancient DNA analysis can and cannot reveal, and those limits deserve explicit discussion.<\/p>\n
The pigmentation predictions \u2014 dark to black skin, blue eyes \u2014 are probabilistic rather than certain.<\/p>\n
They are based on the comparison of genetic variants to patterns established in living populations, and the statistical confidence of those predictions depends on how many relevant variants were recovered, how well-characterized those variants are in modern genomic studies, and how applicable the modern reference populations are to the ancient context.<\/p>\n
The researchers themselves were explicit about this.<\/p>\n
<\/p>\n
They did not say that Cheddar Man definitely had dark skin and blue eyes.<\/p>\n
They said that the genetic evidence most strongly supported those characteristics.<\/p>\n
The probability was high enough to be informative and to inform the facial reconstruction, but it was not certainty.<\/p>\n
There is also a deeper limit to what genetic pigmentation prediction can tell us: the relationship between specific genetic variants and physical appearance is established in modern populations, and those populations have genetic backgrounds that may differ in subtle ways from a ten-thousand-year-old individual.<\/p>\n
The variants we identify as associated with dark or light skin in modern humans may have had slightly different effects in the context of ancient genomes that differed in other ways.<\/p>\n
<\/p>\n
This is a small caveat for the primary findings \u2014 the broad direction of the prediction (dark skin rather than light skin) is robust even if the specific shade cannot be pinpointed \u2014 but it is worth noting that ancient DNA research is always working with incomplete information and probabilistic inferences rather than direct observation.<\/p>\n
Beyond the pigmentation question, DNA cannot tell us most of what we would want to know about a person’s life.<\/p>\n
It does not tell us what language Cheddar Man spoke, what his social relationships were, what stories his community told, what ceremonies they performed, what he personally experienced in his twenty-odd years of life.<\/p>\n
The genome is a biological blueprint, not a biography.<\/p>\n
The facial reconstruction based on the DNA findings is a scientific inference, not a photograph.<\/p>\n
<\/p>\n
The model makers’ skills and the genetic analysis produced a plausible representation of what Cheddar Man might have looked like.<\/p>\n
But the specific contour of his face, the expression in his eyes, the precise shade of his skin \u2014 these are approximations at best.<\/p>\n
The Mesolithic Diet: What Cheddar Man Ate<\/p>\n
While the DNA analysis provided the headline-grabbing findings about appearance, the broader archaeological context of Mesolithic Britain gives us a richer picture of the world Cheddar Man inhabited and the food that sustained him.<\/p>\n
The Mesolithic diet was varied, rich in animal protein, and entirely dependent on what the landscape could provide without cultivation or animal husbandry.<\/p>\n
<\/p>\n
Stable isotope analysis \u2014 a technique that examines the ratios of specific chemical isotopes in bone collagen, which reflect the composition of the diet \u2014 has been applied to Mesolithic skeletons across Britain and Europe and reveals a consistent pattern: high protein intake, primarily from terrestrial mammals and freshwater fish.<\/p>\n
At Gough’s Cave specifically, the archaeological deposits contain the bones of red deer, wild horse, giant deer (also called Irish elk, though it was found across Europe), and various smaller mammals.<\/p>\n
Freshwater fish were likely important, though fish bones are fragile and may not preserve as well as mammal bones.<\/p>\n
Plant foods \u2014 nuts, berries, roots, seeds \u2014 would have been seasonally important, particularly in summer and autumn, though plant remains are often poorly preserved in archaeological sites.<\/p>\n
The Mesolithic world of Britain was not the impoverished, hand-to-mouth existence that some earlier accounts implied.<\/p>\n
<\/p>\n
The postglacial environment was actually extraordinarily productive \u2014 a world of dense forests, rich river systems, productive coastlines, and abundant game.<\/p>\n
For hunter-gatherers with the knowledge to exploit these resources, caloric sufficiency was generally achievable, as evidenced by Cheddar Man’s healthy teeth and well-nourished skeleton.<\/p>\n
What Mesolithic hunter-gatherers lacked was the ability to produce food \u2014 to grow crops, to raise livestock, to store grain through the winter.<\/p>\n
Their survival depended on their knowledge of where food could be found at each season, their skill at hunting and fishing, and the accumulated ecological knowledge that allowed them to move efficiently through the landscape and exploit its resources.<\/p>\n
Cheddar Man would have been part of a community with this knowledge \u2014 a community that knew the Mendip Hills and the surrounding landscape intimately, that had learned through generations of experience where the red deer moved in autumn, where the fish ran in spring, where the best nuts could be gathered in summer.<\/p>\n
<\/p>\n
The Cave Itself As Landscape<\/p>\n
Gough’s Cave in the Mesolithic was not, as it is today, a tourist attraction with a gift shop at the entrance and electric lighting throughout.<\/p>\n
It was a dark, cool, and potentially sacred space at the edge of the landscape that Mesolithic communities moved through.<\/p>\n
The Mendip Hills offered a variety of resources: upland hunting ground, limestone springs, river valleys with fish and water mammals, and the caves themselves.<\/p>\n
The caves were used for various purposes across the Mesolithic and Paleolithic \u2014 shelter from extreme weather, possibly ceremonial spaces, and, as the evidence suggests, burial locations.<\/p>\n
<\/p>\n
The presence of the cannibalistic deposits from the earlier Paleolithic occupation of Gough’s Cave adds a layer of complexity to the site’s history.<\/p>\n
Whatever practices those earlier visitors were engaged in, they predated Cheddar Man by approximately four to five thousand years.<\/p>\n
The Paleolithic people who processed bodies in the cave were not the same people as Cheddar Man’s community, and the practices they engaged in may not have been part of Cheddar Man’s world at all.<\/p>\n
The specific nature of Cheddar Man’s burial \u2014 or the depositional event that placed his remains in the cave \u2014 is not fully established.<\/p>\n
He may have been deliberately buried there by his community, in which case the cave had ceremonial or spiritual significance as a burial place.<\/p>\n
<\/p>\n
He may have died there accidentally and been covered by natural sediment accumulation over time.<\/p>\n
He may have been placed there for practical reasons, taking advantage of the cool cave environment for body preservation.<\/p>\n
The archaeological evidence cannot definitively distinguish between these possibilities.<\/p>\n
The presence of a more or less complete skeleton \u2014 rather than scattered or disturbed bones \u2014 suggests that the body was not significantly disturbed after deposition, whether the deposition was deliberate or natural.<\/p>\n
The Neolithic Transformation: What Came After<\/p>\n
<\/p>\n
The world that Cheddar Man inhabited was transformed, beginning roughly 6,000 years ago, by the arrival of farming.<\/p>\n
The Neolithic transition in Britain \u2014 the shift from hunter-gatherer subsistence to farming and animal husbandry \u2014 was one of the most profound transformations in the island’s history.<\/p>\n
It involved not just changes in food production but changes in settlement patterns, in the organization of communities, in the built environment (Neolithic people built the monuments and megalithic structures that dot the British landscape), and in the genetics of the population.<\/p>\n
The ancient DNA evidence has established that the Neolithic transition in Britain was driven largely by the immigration of new people from continental Europe, who were themselves part of the agricultural expansion that had originated in Anatolia roughly 10,000 to 12,000 years ago.<\/p>\n
<\/p>\n
These Neolithic farmers had a genetic signature that was distinct from the Western Hunter-Gatherers \u2014 they were more closely related to modern populations of the Middle East and southern Europe, and they carried the lighter pigmentation genes that the WHG lacked.<\/p>\n
When these farmers arrived in Britain, they largely replaced the indigenous hunter-gatherer population.<\/p>\n
The genetic evidence suggests that within a few thousand years of the farmers’ arrival, the indigenous WHG ancestry had been diluted to a very small fraction of the British gene pool.<\/p>\n
This was not a gradual blending; it was a fairly rapid demographic replacement, probably driven by the higher population densities that farming could support relative to hunting and gathering.<\/p>\n
The mechanisms of this replacement are debated.<\/p>\n
<\/p>\n
Some researchers have suggested that disease \u2014 the new infectious diseases that came with farming communities and their domesticated animals \u2014 may have played a role in depopulating the indigenous hunter-gatherer communities.<\/p>\n
Others emphasize the demographic advantage of farming populations, which could support substantially more people per square kilometer than hunting and gathering.<\/p>\n
Whatever the specific mechanisms, the genetic evidence is clear: within a few millennia of the Neolithic farmers’ arrival in Britain, the Western Hunter-Gatherers were largely gone, their genetic heritage reduced to the roughly ten percent contribution that their descendants carry in modern British genomes.<\/p>\n
Cheddar Man was part of a population that was replaced.<\/p>\n
<\/p>\n
His world ended not through dramatic conquest but through the slow demographic pressure of a more productive subsistence system.<\/p>\n
The Bronze Age Transformation: The Third Wave<\/p>\n
The genetic history of British populations involves not two but three major population episodes during the time when genetic history is recoverable.<\/p>\n
After the Neolithic farmers \u2014 who brought lighter pigmentation, the ability to raise livestock and crops, and the construction of megalithic monuments \u2014 came a third major population movement, beginning roughly 5,000 years ago.<\/p>\n
This third wave came from the east: from the Pontic-Caspian steppe, the vast grassland north of the Black Sea that is now part of Ukraine, Russia, and Kazakhstan.<\/p>\n
<\/p>\n
The people of the steppe, who are referred to in the ancient DNA literature as Yamnaya people after the culture they represent, had a genetic signature that was distinct from both the Western Hunter-Gatherers and the Neolithic Anatolian farmers.<\/p>\n
The Yamnaya were pastoralists \u2014 herders of cattle, horses, and sheep who moved across the steppe with their animals rather than building permanent settlements.<\/p>\n
They used horses for transportation, possibly among the first people in the world to do so.<\/p>\n
They may have been the first speakers of Proto-Indo-European, the language ancestor of most modern European languages including English, Spanish, French, German, Russian, and many others.<\/p>\n
Beginning roughly 5,000 years ago, Yamnaya-related people began moving into Europe from the east.<\/p>\n
<\/p>\n
Within roughly a thousand years, their genetic signature became dominant across much of Europe.<\/p>\n
In Britain, the Yamnaya-related people appear in the archaeological record associated with the Beaker culture \u2014 the makers of distinctive ceramic vessels who appeared across much of western Europe around 4,500 to 4,000 years ago.<\/p>\n
The genetic impact of the Beaker people in Britain was dramatic.<\/p>\n
Ancient DNA analysis has shown that within a few centuries of the Beaker people’s arrival, approximately ninety percent of the ancestry of people in Britain had shifted to reflect significant Yamnaya-related input.<\/p>\n
The Neolithic farmers who had arrived a few thousand years earlier were themselves largely replaced.<\/p>\n
<\/p>\n
For skin pigmentation, the Yamnaya migration was significant: the Yamnaya carried genetic variants associated with lighter skin pigmentation that were distinct from the variants carried by the Neolithic Anatolian farmers.<\/p>\n
The modern light pigmentation of northern Europeans is the result of multiple population inputs, including both Neolithic and Yamnaya contributions, overlaid on a small residual WHG background.<\/p>\n
Cheddar Man’s dark skin, in this context, reflects the beginning of this story.<\/p>\n
He lived before any of the subsequent population turnovers.<\/p>\n
His genome shows the baseline from which the genetic history of Britain’s Mesolithic people would eventually be transformed beyond recognition.<\/p>\n
The Scientific Community’s Response<\/p>\n
<\/p>\n
The 2018 Cheddar Man study was published in a peer-reviewed form and received broadly positive reception from the scientific community, though with some nuances that deserve mention.<\/p>\n
The general findings \u2014 the dark pigmentation, the blue eyes, the WHG ancestry \u2014 were consistent with what earlier ancient DNA research had established for other Mesolithic European individuals, and this consistency across multiple independent analyses strengthened confidence in the conclusions.<\/p>\n
The specific finding for Cheddar Man was not a radical departure from prior expectations in the field; it was a new data point that fit an emerging picture.<\/p>\n
The whole-genome sequencing was praised as a methodological advance.<\/p>\n
<\/p>\n
Earlier ancient DNA analyses of Mesolithic individuals had been based on lower-coverage sequencing or targeted analysis of specific genome regions; the Cheddar Man whole-genome represented a more complete and powerful dataset.<\/p>\n
Some scientists emphasized the importance of acknowledging the probabilistic nature of the pigmentation predictions.<\/p>\n
While the dark-skin finding was reported with confidence in the media, researchers in the field noted that pigmentation prediction from ancient DNA involves statistical inference rather than direct observation, and that the specific intensity of pigmentation \u2014 precisely how dark the skin was \u2014 cannot be determined with high precision from genetic data alone.<\/p>\n
The identification of Cheddar Man as belonging to the Western Hunter-Gatherer population was not controversial; the genetic markers for WHG ancestry are well-established in the literature, and Cheddar Man’s genome showed them clearly.<\/p>\n
<\/p>\n
Why This Changes The Picture Of European Prehistory<\/p>\n
The significance of the Cheddar Man findings extends far beyond the characteristics of a single individual.<\/p>\n
They are a window into a world that was fundamentally different from anything that modern Europeans have experienced or that history has recorded.<\/p>\n
The Mesolithic Europe that Cheddar Man inhabited was a world in which the peoples of the continent \u2014 from Britain in the northwest to Spain in the southwest, from Germany in the north to the Balkans in the southeast \u2014 shared a common genetic ancestry, a common broadly similar lifestyle (hunting and gathering), and, as the ancient DNA evidence suggests, a broadly similar appearance: dark skin, light eyes, dark hair.<\/p>\n
This was not the Europe of the Romans, who would have found Mesolithic Europeans as exotic as the peoples of Africa or Asia.<\/p>\n
<\/p>\n
It was not the Europe of the medieval chroniclers, who would have had no frame of reference for it.<\/p>\n
It was not even the Europe of the Neolithic monuments \u2014 Stonehenge, the passage tombs of Ireland, the megaliths of Brittany \u2014 because those were built by the people who replaced the Mesolithic population.<\/p>\n
It was a different Europe, inhabited by people who left no writing, built no permanent monuments, and whose existence we know primarily through the bones they left behind in caves and middens and buried pits, and now \u2014 increasingly \u2014 through the DNA those bones preserved.<\/p>\n
The ancient DNA revolution has allowed us to see this world more clearly than was possible even ten years ago.<\/p>\n
<\/p>\n
And what it shows is that the people who first inhabited postglacial Europe looked nothing like the populations that live there today, that the genetic and phenotypic makeup of European populations is the result of not one but multiple major population turnovers over the past ten thousand years, and that assumptions about what “originally European” means are fundamentally wrong.<\/p>\n
Cheddar Man is the most vivid single example of this broader story.<\/p>\n
His dark skin and blue eyes are not just an interesting characteristic of one individual; they are a data point that challenges assumptions about the deep history of the people who would come to inhabit Britain.<\/p>\n
The Living Descendants: Ten Percent Of Britain<\/p>\n
The statement that approximately ten percent of the ancestry of modern white British people can be traced to the Western Hunter-Gatherer population needs some unpacking, because it is easily misunderstood.<\/p>\n
It does not mean that one in ten modern British people has a WHG ancestor in the recent genealogical past.<\/p>\n
<\/p>\n
In genealogical terms, the number of ancestors doubles every generation \u2014 ten generations back, you have more than a thousand ancestors.<\/p>\n
Going back three hundred to four hundred generations, you effectively have an ancestor in every population that existed in a geographic area connected to your ancestry.<\/p>\n
What the ten percent figure means is something different: approximately ten percent of the genetic material carried by modern white British people is most similar, in its specific combination of variants, to the variants found in WHG populations like Cheddar Man.<\/p>\n
In the language of population genetics, WHG-like ancestry constitutes about ten percent of the ancestry proportion of modern British people.<\/p>\n
<\/p>\n
The other ninety percent of that ancestry comes primarily from the Neolithic Anatolian farmers and the Bronze Age steppe pastoralists \u2014 the two later populations that substantially replaced the WHG.<\/p>\n
This means that all modern British people carry some genetic inheritance from the population to which Cheddar Man belonged.<\/p>\n
The inheritance is diluted to a minority of their overall ancestry, but it is present.<\/p>\n
Some specific genetic variants that were carried by Cheddar Man and his contemporaries survive in modern British genomes, just in lower frequencies than the variants introduced by later populations.<\/p>\n
The evolutionary fate of the Western Hunter-Gatherers is, in this sense, not extinction.<\/p>\n
<\/p>\n
They were genetically absorbed rather than entirely replaced.<\/p>\n
Their descendants survive, but the descendants are the product of ten thousand years of demographic mixing, and the WHG heritage is a minority thread in a much more complex genetic tapestry.<\/p>\n
Doggerland: The Lost World Of Britain’s Mesolithic<\/p>\n
One of the most evocative dimensions of the Cheddar Man story is the world he was connected to: the now-submerged landscape of Doggerland.<\/p>\n
When Cheddar Man was alive, the British Isles were not yet islands.<\/p>\n
<\/p>\n
The land that is now the bed of the southern North Sea was above water \u2014 a vast plain of rivers, lakes, marshes, and forests that connected what is now eastern England to what is now Denmark and the Netherlands.<\/p>\n
This was inhabited land, a significant part of the Mesolithic world of northern Europe.<\/p>\n
The communities that lived on Doggerland were connected to the communities in Britain.<\/p>\n
People moved across the landscape, following game, maintaining social relationships, exchanging mates and ideas and material goods across what was not yet a stretch of water but simply more land.<\/p>\n
Britain’s Mesolithic inhabitants were not isolated islanders; they were part of a continental-scale network of communities that occupied the full range of the postglacial northwest European landscape.<\/p>\n
As sea levels rose \u2014 steadily, over centuries and millennia, as the great ice sheets melted \u2014 Doggerland shrank.<\/p>\n
<\/p>\n
The rivers became estuaries.<\/p>\n
The lakes became inlets.<\/p>\n
The forests were inundated.<\/p>\n
What had been a productive and inhabited landscape became, over several thousand years, the floor of the North Sea.<\/p>\n
This inundation happened over a long enough period that people could adapt \u2014 could move to higher ground as their familiar landscape disappeared underwater.<\/p>\n
But there was also at least one more catastrophic event: a submarine landslide on the Norwegian continental shelf, approximately 8,200 years ago, triggered a tsunami that struck the North Sea coast of Doggerland.<\/p>\n
This event, known as the Storegga Slide, may have inundated large areas of low-lying Doggerland rapidly and catastrophically.<\/p>\n
<\/p>\n
By the time this had happened, the Mesolithic populations in Britain were already isolated from their continental counterparts.<\/p>\n
The rising sea level had made the English Channel and the southern North Sea impassable, cutting off the continuous land connection that had linked Britain to Europe.<\/p>\n
Britain became an island, and its Mesolithic inhabitants became, in a practical sense, a different population from their continental neighbors \u2014 able to trade and communicate by boat, but no longer part of the same continuous landscape network.<\/p>\n
Cheddar Man was born before or during this process of isolation.<\/p>\n
<\/p>\n
The specific trajectory of the rising seas relative to his lifetime is uncertain, but the broad context is that he lived at the end of the period of land connectivity and during the beginning of Britain’s existence as a geographically separate entity.<\/p>\n
What The Cheddar Man Finding Means For The Study Of Race<\/p>\n
The Cheddar Man finding has been invoked in discussions about race \u2014 specifically, about the assumption that light skin is somehow inherently or originally “European” \u2014 and the finding’s implications for those discussions deserve careful treatment.<\/p>\n
The genetic finding is clear: the people who first established continuous habitation in Britain after the last Ice Age had dark pigmentation.<\/p>\n
The modern association between European identity and light skin reflects genetics that were introduced into European populations primarily by the Neolithic and Bronze Age migrations, not characteristics that were present from the beginning of European occupation.<\/p>\n
<\/p>\n
This is scientifically significant.<\/p>\n
It demonstrates that the combination of traits associated with “European” appearance in the modern world is not ten thousand years old \u2014 it is at most five to eight thousand years old, and some elements of it are more recent than that.<\/p>\n
The characteristic light skin of northern Europeans is not ancient; it is derived.<\/p>\n
More broadly, the Cheddar Man finding is part of a larger pattern that ancient DNA research has established: the genetic characteristics of any modern population are the product of multiple migrations, population turnovers, and admixture events that occurred over thousands of years.<\/p>\n
There is no population anywhere in the world whose ancestry is simply continuous from some early state; all populations are the products of movement, mixing, and transformation.<\/p>\n
<\/p>\n
This is not merely a European story.<\/p>\n
Ancient DNA research in Africa, Asia, the Americas, and the Pacific has consistently shown that the population histories of all regions are far more complex than<\/p>\n
The Skull Damage: What We Know And Don’t Know<\/p>\n
The question of how Cheddar Man died \u2014 what caused the damage visible on his skull \u2014 is one of the most persistently discussed unsolved questions about him.<\/p>\n
The damage consists of holes or perforations in the skull that have been analyzed by multiple researchers over the decades.<\/p>\n
<\/p>\n
The interpretation of such damage is genuinely difficult, because similar-looking damage can be caused by several entirely different processes.<\/p>\n
The first possibility is violence.<\/p>\n
A blow to the head \u2014 from a weapon, from a fall, from some form of interpersonal conflict \u2014 could produce the kind of skull damage visible in Cheddar Man’s remains.<\/p>\n
Interpersonal violence in Mesolithic communities is not unknown from the archaeological record; other Mesolithic sites in Europe have produced skeletal evidence of violence.<\/p>\n
Whether the Mesolithic was a particularly violent or relatively peaceful era is itself debated, with different sites and different researchers producing different assessments.<\/p>\n
The second possibility is taphonomic damage \u2014 damage caused not by violence but by the natural processes of burial and preservation.<\/p>\n
<\/p>\n
Animal scavenging, the pressure of sediment overlying the bones, the movement of water through the cave, root action, and countless other natural agents can produce damage to buried bones that superficially resembles injury or violence.<\/p>\n
Distinguishing taphonomic from ante-mortem damage requires careful analysis of the specific characteristics of the damage \u2014 its location, the presence or absence of healing, the edge characteristics.<\/p>\n
The third possibility is excavation damage \u2014 damage caused by the excavation itself in 1903, when Cheddar Man was removed from the sediment by workers whose methods were not as careful as modern excavation protocols would require.<\/p>\n
Researchers have suggested that the skull damage may indicate a violent end, perhaps a blow to the head.<\/p>\n
<\/p>\n
But this has not been established with certainty.<\/p>\n
The evidence is ambiguous, and multiple interpretations remain plausible.<\/p>\n
That ambiguity is itself part of the human story.<\/p>\n
Here is a person who died young \u2014 in his early to mid-twenties \u2014 in what might have been violent circumstances.<\/p>\n
Or in what might have been an accident.<\/p>\n
Or whose injuries occurred after death.<\/p>\n
The uncertainty about how he died is a reminder that the archaeological record, even when exceptionally well-preserved as at Gough’s Cave, leaves most of a life invisible.<\/p>\n
The La Bra\u00f1a Connection: He Was Not Alone<\/p>\n
<\/p>\n
Cheddar Man was not the only Western Hunter-Gatherer individual to have had his genome analyzed before 2018, though he was the oldest British individual to receive whole-genome sequencing.<\/p>\n
The La Bra\u00f1a individual, found at a site in the mountains of Le\u00f3n in northwestern Spain, had been analyzed in a landmark 2012 paper.<\/p>\n
La Bra\u00f1a 1, as the individual is designated, lived approximately 7,000 years ago \u2014 roughly 3,000 years after Cheddar Man, but still well within the Mesolithic period and before the arrival of Neolithic farmers in the Iberian Peninsula.<\/p>\n
The genetic analysis of La Bra\u00f1a 1 showed a striking result: dark skin, blue eyes, dark hair.<\/p>\n
<\/p>\n
The same combination that would later be found for Cheddar Man.<\/p>\n
The connection between the two individuals \u2014 separated by three thousand years and roughly 1,500 kilometers of geography \u2014 is the genetic signature they share.<\/p>\n
Both belonged to the Western Hunter-Gatherer meta-population.<\/p>\n
Both had the pigmentation characteristics that turn out to be typical of that population.<\/p>\n
Both are part of a consistent picture that ancient DNA research has now established for Mesolithic western Europe.<\/p>\n
The La Bra\u00f1a analysis was published in 2012 and received significant scientific attention, but it did not achieve the same level of public engagement as the Cheddar Man study.<\/p>\n
<\/p>\n
The physical facial reconstruction, combined with Cheddar Man’s specific cultural resonance as a British specimen in the context of contemporary British identity debates, amplified the public impact of the 2018 findings in ways that the La Bra\u00f1a publication did not achieve.<\/p>\n
But the scientific finding was not new.<\/p>\n
It was a confirmation and extension, in a new specimen, of a pattern that earlier ancient DNA work had already established.<\/p>\n
This consistency across independent analyses \u2014 multiple different specimens from multiple different sites, analyzed by different research teams, all showing the same dark-skin-blue-eyes combination \u2014 is precisely what gives the finding its scientific strength.<\/p>\n
The Mesolithic Cave Art Question<\/p>\n
<\/p>\n
One striking contrast between Mesolithic and Paleolithic archaeology is the evidence for cave art.<\/p>\n
The spectacular painted caves of southern France and Spain \u2014 Lascaux, Altamira, Chauvet \u2014 date to the Paleolithic period, when the ancestors of the Western Hunter-Gatherers (or related populations) were painting bison and horses and handprints on the walls of limestone caves.<\/p>\n
The Mesolithic is largely without cave art.<\/p>\n
There are some Mesolithic rock art sites in northern Europe \u2014 Scandinavian rock carvings, for example \u2014 but the explosion of Paleolithic cave painting does not have a clear Mesolithic equivalent.<\/p>\n
Why the transition from the rich cave art of the Paleolithic to the relative paucity of Mesolithic art occurred is a question without a fully satisfying answer.<\/p>\n
<\/p>\n
One possibility is that the shift in subsistence and mobility patterns associated with the postglacial environment \u2014 from a world dominated by the great herds of ice-age megafauna to a world of forest-adapted, more diversified hunting \u2014 affected the specific practices of representation.<\/p>\n
Another is that Mesolithic art was produced on perishable materials \u2014 wood, skin, bark \u2014 that do not survive in the archaeological record.<\/p>\n
Another is that the cave art of the Paleolithic had specific ceremonial functions tied to specific aspects of Paleolithic life that changed in the Mesolithic.<\/p>\n
Gough’s Cave itself is one of the caves where the Paleolithic inhabitants left traces \u2014 not cave paintings, but the worked bones and tools of the earlier occupation.<\/p>\n
Cheddar Man, who came to the cave roughly 4,000 to 5,000 years after the Paleolithic occupants, inhabited a cultural world that was in some ways continuous with the Paleolithic and in other ways different.<\/p>\n
<\/p>\n
Whether the Mesolithic people who used Gough’s Cave decorated its walls or practiced other forms of art we cannot easily detect is not established.<\/p>\n
The absence of evidence is not evidence of absence \u2014 the cool, damp cave environment that preserved Cheddar Man’s DNA might also have preserved other organic materials, but the history of excavation at the site does not allow us to be certain about what was and was not present.<\/p>\n
The Petrous Bone: The Key To Ancient DNA<\/p>\n
The technical key to the Cheddar Man whole-genome analysis was the petrous bone \u2014 and the story of how researchers identified this bone as the optimal source of ancient DNA is itself a story of methodological progress.<\/p>\n
The petrous bone is part of the temporal bone at the base of the skull.<\/p>\n
<\/p>\n
It forms the bony covering of the inner ear structures \u2014 the cochlea and semicircular canals \u2014 and is one of the densest bones in the human body.<\/p>\n
Its density is so extreme that it was once described as “rock-like” (the name derives from the Latin “petra,” meaning rock or stone).<\/p>\n
This density matters for DNA preservation because it limits the penetration of water, microbial activity, and other agents of decomposition that destroy DNA in less dense bone.<\/p>\n
The same density that makes the petrous bone difficult to cut also makes it an outstanding preserve of the genetic material it contains.<\/p>\n
The identification of the petrous bone as the best source of ancient DNA was made primarily by Pontus Skoglund and colleagues in a 2014 paper in Philosophical Transactions of the Royal Society B, which analyzed DNA yield from different skeletal elements.<\/p>\n
<\/p>\n
The paper found that the petrous bone consistently yielded orders of magnitude more endogenous (authentic ancient) DNA than other skeletal elements, and that this advantage held across specimens from different environmental conditions and different ages.<\/p>\n
Before this discovery, ancient DNA researchers often used teeth or the compact bone of limb shafts as their primary samples.<\/p>\n
The identification of the petrous bone as far superior transformed the field: it made it possible to obtain whole genomes from specimens that would previously have yielded only limited genetic information.<\/p>\n
For the Cheddar Man analysis, this was critical.<\/p>\n
The researchers drilled into the petrous portion of Cheddar Man’s temporal bone, extracting just a few milligrams of bone powder \u2014 a minimally destructive sample \u2014 that contained enough DNA to support whole-genome sequencing.<\/p>\n
The cave environment contributed additional preservation: the cool, stable temperature and the mineral-rich limestone environment that characterizes Gough’s Cave had helped prevent the degradation of the biological material over ten thousand years.<\/p>\n
<\/p>\n
The petrous bone in such an environment is about as favorable a combination for ancient DNA preservation as exists in the archaeological record.<\/p>\n
The Wader’s World: Britain At The End Of The Ice Age<\/p>\n
Britain at the end of the last Ice Age \u2014 approximately 12,000 to 10,000 years ago \u2014 was a profoundly different landscape from the one that exists today, and understanding it helps situate Cheddar Man in his actual world.<\/p>\n
The ice had already begun retreating from much of Britain by this point, but the landscape that remained was shaped by its glacial past: U-shaped valleys cut by glaciers, moraines of deposited glacial debris, outwash plains of sand and gravel, and a geology radically reshaped by the weight of ice.<\/p>\n
The soils were young and often thin \u2014 the long-established forest soils of the previous interglacial had been stripped away by the ice.<\/p>\n
<\/p>\n
Into this newly ice-free landscape, plants and animals were moving north, recolonizing the habitable territory that the retreating glaciers revealed.<\/p>\n
Birch and Scots pine were among the first trees to establish; they grew into the early postglacial forest that covered much of Britain within a few thousand years.<\/p>\n
As the climate continued to warm, hazel, elm, and eventually oak followed, creating the dense mixed forest that characterized the later Mesolithic.<\/p>\n
Animals returned with the plants.<\/p>\n
Red deer were among the most significant prey species of the Mesolithic.<\/p>\n
Wild boar were common.<\/p>\n
<\/p>\n
Aurochs \u2014 the massive wild ancestor of modern cattle, standing nearly two meters at the shoulder \u2014 ranged across the postglacial landscape.<\/p>\n
Brown bears and wolves were present.<\/p>\n
Beavers colonized the rivers.<\/p>\n
The Mendip Hills, where Cheddar Gorge is located, offered a specific combination of resources: upland plateau suitable for hunting, the limestone gorge itself with its water source and cave shelter, and access to the lowlands and river valleys to the north and south.<\/p>\n
The limestone geology of the Mendips meant that water flowing through the hills emerged as springs \u2014 reliable water sources that were particularly important in a world without wells or water storage infrastructure.<\/p>\n
Cheddar Man and his community would have moved through this landscape according to seasonal rhythms: to the upland hunting grounds in summer, to the valleys and lowlands for winter shelter, to specific locations for specific resources at the times those resources were available.<\/p>\n
<\/p>\n
The cave would have been one point in this seasonal round \u2014 a place of particular significance, perhaps because of the water source, perhaps because of the shelter, perhaps because of its role in burial practices, perhaps for multiple overlapping reasons.<\/p>\n
The Teeth: A Window Into Health<\/p>\n
Beyond the DNA, Cheddar Man’s teeth tell their own story about his health and his diet.<\/p>\n
His teeth were in notably good condition.<\/p>\n
Unlike the teeth of Neolithic farmers \u2014 who began eating carbohydrates and cooked starchy foods in large quantities, leading to significant dental caries (tooth decay) \u2014 Cheddar Man’s teeth showed little evidence of decay.<\/p>\n
This is consistent with a diet high in protein and low in fermentable carbohydrates: meat, fish, nuts, and berries produce relatively little dental decay compared to bread, porridge, and other processed plant foods.<\/p>\n
<\/p>\n
He had wear on his teeth consistent with a diet that required substantial chewing \u2014 raw or lightly processed meat and plant foods leave more wear than soft cooked foods.<\/p>\n
He may also have used his teeth as a tool, in the way that is common in many hunter-gatherer cultures: holding materials while working them with the hands, softening hides by chewing, and performing various other tasks that leave characteristic marks on the teeth.<\/p>\n
The absence of significant dental disease is itself a historical statement.<\/p>\n
The widespread dental caries and periodontal disease that became common with the adoption of agriculture \u2014 and that remain common in industrialized populations today \u2014 were largely absent from Mesolithic populations.<\/p>\n
From the perspective of dental health, the hunter-gatherer diet was superior to the agricultural diet, even though agricultural production could support far larger populations.<\/p>\n
<\/p>\n
This paradox \u2014 that the shift to agriculture, which supported larger populations, also made those populations less healthy in various measurable ways \u2014 is one of the more counterintuitive findings of paleopathology.<\/p>\n
Cheddar Man’s healthy teeth are part of the evidence for this paradox.<\/p>\n
The Question Of Language<\/p>\n
Cheddar Man could speak.<\/p>\n
The capacity for language is universal in anatomically modern humans, present in all populations everywhere since at least 100,000 years ago.<\/p>\n
His brain was the same size and organization as any modern human brain.<\/p>\n
His vocal anatomy was the same.<\/p>\n
But what language did he speak?<\/p>\n
<\/p>\n
This question has no answer.<\/p>\n
The languages of Mesolithic western Europe were completely replaced by the languages brought by subsequent immigrant populations.<\/p>\n
The Neolithic farmers who replaced the WHG across Europe brought their languages with them.<\/p>\n
The Bronze Age steppe pastoralists brought Proto-Indo-European, which is the ancestor of virtually all the languages of modern Europe including English.<\/p>\n
Whatever language Cheddar Man spoke \u2014 whatever words his community used for the hills they hunted, the animals they pursued, the ceremonies they practiced, the stories they told \u2014 is entirely gone.<\/p>\n
Not a word survives.<\/p>\n
<\/p>\n
Not a name.<\/p>\n
Not a story.<\/p>\n
The only traces of pre-agricultural European languages are a few words in modern languages that do not have Indo-European roots and that may be survivals from an earlier stratum \u2014 words that appear to have been borrowed from whatever languages were spoken before the Indo-European expansion.<\/p>\n
The specific identification of such words is highly uncertain, and the linguistic history of prehistoric Europe is largely inaccessible.<\/p>\n
Cheddar Man’s language was presumably related to the languages of other Western Hunter-Gatherer communities across western Europe \u2014 the people of what is now Spain, France, and northern Germany, with whom his ancestors had shared territory and with whom his population had genetic connections.<\/p>\n
<\/p>\n
Whether these communities spoke related languages is plausible but undemonstrable.<\/p>\n
The silence is one of the deepest silences in human history.<\/p>\n
The Kennis Brothers And The Art Of Reconstruction<\/p>\n
The physical reconstruction of Cheddar Man produced by Adrie and Alfons Kennis is a significant work that represents both scientific inference and artistic skill.<\/p>\n
The Kennis brothers \u2014 based in the Netherlands \u2014 are specialists in paleo-art: the production of scientifically informed representations of ancient humans and other prehistoric creatures.<\/p>\n
Their work includes reconstructions of Neanderthals, Homo heidelbergensis, and various other ancient human species, as well as reconstructions of specific individuals like Cheddar Man.<\/p>\n
<\/p>\n
Their method involves first creating a detailed three-dimensional reconstruction of the skull, working from the high-resolution scan to produce a physical replica.<\/p>\n
Then soft tissue reconstruction is built up over this skull base, using established forensic anthropology guidelines about the typical relationships between skull measurements and soft tissue depth at various facial points.<\/p>\n
These guidelines \u2014 derived from studies of modern populations \u2014 allow reconstruction of the general contour of the face from the underlying bone structure.<\/p>\n
The specific characteristics derived from the DNA analysis \u2014 the dark skin, the blue eyes, the dark curly hair \u2014 are then applied to the physical reconstruction.<\/p>\n
The model makers worked with the genetic research team to translate the probabilistic genetic predictions into specific visual features.<\/p>\n
<\/p>\n
The result is a representation that captures something real: the general facial structure derived from the skull, the pigmentation characteristics derived from the DNA, and the overall impression of an individual.<\/p>\n
But it is also inevitably an interpretation.<\/p>\n
The specific expression, the exact texture of the skin, the precise curl of the hair \u2014 these are artistic choices made within the constraints of the available evidence.<\/p>\n
The Cheddar Man reconstruction is one of the more scientifically grounded ancient human reconstructions ever produced, because the combination of high-quality skull scanning and high-quality genetic data provided stronger constraints on the reconstruction than most comparable projects.<\/p>\n
But it is still an interpretation, not a portrait.<\/p>\n
<\/p>\n
That caveat does not diminish the impact.<\/p>\n
The face that emerged from the reconstruction \u2014 a young man with dark skin and blue eyes, looking directly at the viewer \u2014 is one of the most striking images produced by archaeological science in recent years.<\/p>\n
It insists on the humanity of a person who might otherwise exist only as a technical dataset.<\/p>\n
The Stable Isotope Evidence: Eating Through The Seasons<\/p>\n
While the DNA analysis provided the headline findings about Cheddar Man’s appearance and ancestry, other analytical methods applied to his bones provide complementary information about his diet and mobility.<\/p>\n
<\/p>\n
Stable isotope analysis measures the ratios of specific chemical isotopes in bone collagen.<\/p>\n
The most commonly used isotopes are carbon (comparing the ratios of carbon-12 and carbon-13) and nitrogen (comparing the ratios of nitrogen-14 and nitrogen-15).<\/p>\n
These ratios reflect the composition of the diet \u2014 specific isotope ratios are characteristic of specific types of food, and the isotope ratios in bone collagen reflect the average diet over the years during which that collagen was being formed.<\/p>\n
The carbon isotope ratios in Mesolithic hunter-gatherers from Britain typically indicate a diet based primarily on terrestrial mammals, with some contribution from freshwater resources in some individuals.<\/p>\n
<\/p>\n
The nitrogen isotope ratios are typically elevated compared to those of later farming populations, indicating a higher proportion of animal protein in the diet.<\/p>\n
For Cheddar Man specifically, stable isotope analysis is consistent with the diet that would be expected from a Mesolithic hunter-gatherer in the Mendip Hills: primarily terrestrial game, with possible contributions from freshwater fish and plant foods that are less isotopically visible.<\/p>\n
The specific composition of his diet across different seasons is harder to reconstruct from isotope analysis, which gives an average picture rather than a seasonal one.<\/p>\n
Sequential sampling of different regions of a tooth \u2014 teeth grow incrementally, like tree rings, with each increment reflecting the diet during the period when that part of the tooth was forming \u2014 can in principle provide a seasonal dietary record.<\/p>\n
<\/p>\n
Whether this approach has been applied to Cheddar Man’s teeth is not fully established in the publicly available literature.<\/p>\n
The Three-Part Story Of European Ancestry<\/p>\n
The Cheddar Man finding fits into what geneticists have described as the three-way admixture story of European ancestry \u2014 the finding that modern Europeans are the product of three major source populations, each of which contributed distinct genetic components.<\/p>\n
The first component is the Western Hunter-Gatherer ancestry, represented by Cheddar Man and his contemporaries.<\/p>\n
This component is the oldest continuous European ancestry, representing the postglacial hunter-gatherer populations that inhabited western and central Europe.<\/p>\n
In modern white British people, this component represents approximately ten percent of ancestry.<\/p>\n
<\/p>\n
The second component is the Anatolian Neolithic farmer ancestry, brought by the early farmers who migrated from what is now Turkey into southeastern Europe and then across the continent beginning roughly 9,000 years ago.<\/p>\n
In modern white British people, this component represents the plurality of ancestry \u2014 roughly forty to fifty percent.<\/p>\n
The third component is the Ancient North Eurasian \/ steppe pastoralist ancestry, brought by the Bronze Age migrations from the Pontic-Caspian steppe.<\/p>\n
In modern white British people, this component represents roughly thirty to forty percent.<\/p>\n
The relative proportions of these three components vary across modern European populations: southern Europeans have more Anatolian Neolithic farmer ancestry and less steppe ancestry; northern and eastern Europeans have more steppe ancestry.<\/p>\n
British people have a mixture that reflects both the Neolithic farming expansion from the south and the Bronze Age steppe expansion from the east.<\/p>\n
<\/p>\n
Cheddar Man, with his pure Western Hunter-Gatherer ancestry, represents the starting point before any of the subsequent admixture occurred.<\/p>\n
He is, genetically, a simpler story than modern people: one source population, without the later layers.<\/p>\n
The layers came later.<\/p>\n
The Story The Land Tells<\/p>\n
The Mendip Hills of Somerset are, today, a landscape of limestone grassland and hawthorn hedgerows, ancient dry-stone walls, and the occasional hill fort from the Iron Age.<\/p>\n
The modern landscape is almost entirely agricultural \u2014 shaped by ten thousand years of human intervention, from the Neolithic clearance of the primeval forest through the medieval field systems to the modern farm economy.<\/p>\n
Under this agricultural landscape is the geology: the carboniferous limestone of the Mendips, the same rock that forms the walls of Cheddar Gorge and the chambers of Gough’s Cave.<\/p>\n
<\/p>\n
The limestone preserves things \u2014 not in the sentimental sense, but in the literal chemical sense.<\/p>\n
Cool, alkaline, stable.<\/p>\n
Resistant to the acid that destroys organic matter.<\/p>\n
A matrix that can protect biological material from the processes of decay.<\/p>\n
Gough’s Cave is still there.<\/p>\n
Tourists still walk through it, guided by the electric lights, past the stalactites and the formations.<\/p>\n
In the back of the cave, in the limestone chambers that Cheddar Man knew as darkness and stone, the cool air still moves gently, still maintains the stable low temperature that preserved his bones and his DNA for ten thousand years.<\/p>\n
The cave does not know what it preserved.<\/p>\n
<\/p>\n
It is simply limestone, shaped by water, indifferent to the significance of what it contains.<\/p>\n
But what it contained changed what we know about the people who first called Britain home.<\/p>\n
What it contained is a face, a genome, a story \u2014 small, specific, human \u2014 from a world that existed before any British history was written, before any British history could be written, in the time before Britain was an island.<\/p>\n
The man from the cave looked at this landscape with dark-skinned, blue-eyed attention.<\/p>\n
He knew it in ways that its current inhabitants do not.<\/p>\n
<\/p>\n
He hunted it, traveled it, sheltered in it, and eventually died in it and was covered by its stone.<\/p>\n
The stone gave him back, eventually.<\/p>\n
The DNA told us who he was.<\/p>\n
And who he was turned out to be different from everything we assumed.<\/p>\n
That is the beginning of a better understanding.<\/p>\n
The cave held the secret for ten thousand years.<\/p>\n
The science finally opened the stone.<\/p>\n
The Genetic Basis Of Lactose Intolerance: A Deeper Look<\/p>\n
<\/p>\n
The finding that Cheddar Man was lactose intolerant \u2014 that he carried the ancestral form of the LCT gene that causes lactase production to decline after childhood \u2014 is worth examining in more detail because it illuminates one of the most powerful examples of recent natural selection in human evolution.<\/p>\n
The gene that controls lactase production \u2014 the LCT gene \u2014 has a specific variant, located in a regulatory region upstream of the gene rather than in the gene itself, that allows continued lactase expression throughout adult life.<\/p>\n
This variant, called LP for lactase persistence, is found at high frequencies in populations of northern European descent and in certain African and Middle Eastern populations where cattle herding has a long history.<\/p>\n
In Mesolithic Europe, before the arrival of farming and the domestication of cattle, there was no selective pressure favoring LP.<\/p>\n
<\/p>\n
Wild animals were not available for milking.<\/p>\n
Hunter-gatherers could not make cheese or butter or yogurt.<\/p>\n
The ability to digest lactose after childhood was not useful, and the LP variant was absent or very rare in Mesolithic populations.<\/p>\n
When Neolithic farmers arrived with their cattle, the situation began to change \u2014 but not immediately.<\/p>\n
The ancient DNA evidence shows that early Neolithic farmers did not carry the LP variant at high frequencies either.<\/p>\n
Lactase persistence appears to have spread substantially later, during the Bronze Age and possibly in connection with the steppe pastoralist migrations and the subsequent development of intensive dairy farming.<\/p>\n
<\/p>\n
The natural selection that drove LP to high frequency in northern European populations must have been extremely strong \u2014 among the strongest selection pressures detected in the recent human genome.<\/p>\n
The generation-to-generation advantage of being able to digest milk in a culture that depended heavily on dairy must have been substantial, whether through direct caloric advantage, through reduced disease risk, or through some other mechanism.<\/p>\n
For Cheddar Man, living before dairy animals existed, the absence of LP was not a disability.<\/p>\n
His world did not include cow’s milk.<\/p>\n
The trait only becomes a disadvantage \u2014 a condition we would today call lactose intolerance \u2014 in the context of a dairy-dependent culture that arrived thousands of years after his death.<\/p>\n
The trajectory of LP evolution is a microcosm of the broader story: what counts as an advantage or disadvantage in genetics depends entirely on context, and the context changes.<\/p>\n
<\/p>\n
The Ice Age Before Cheddar Man: The Population That Preceded<\/p>\n
Cheddar Man’s population \u2014 the Western Hunter-Gatherers \u2014 was not the first population to inhabit Britain.<\/p>\n
The island had been home to modern humans going back at least 40,000 years, and possibly longer for earlier human species.<\/p>\n
The earliest anatomically modern humans in Britain are represented by a small number of Paleolithic specimens: Paviland Cave in Wales produced a burial known as the “Red Lady of Paviland” (later identified as a young adult male) dating to approximately 33,000 years ago.<\/p>\n
Kents Cavern in Devon has yielded fragments of jaw bone tentatively dated to roughly 40,000 to 44,000 years ago, among the oldest modern human remains in northwestern Europe.<\/p>\n
<\/p>\n
These early modern humans in Britain were part of a broader Upper Paleolithic population that spread across Europe from roughly 45,000 years ago, replacing the Neanderthals who had previously inhabited the continent.<\/p>\n
Then came the Last Glacial Maximum \u2014 the coldest phase of the last Ice Age, centered around 20,000 to 25,000 years ago.<\/p>\n
The ice sheets expanded dramatically.<\/p>\n
Britain became largely or entirely uninhabitable.<\/p>\n
The people who had been living there \u2014 the ancestors of the early Paleolithic Britons \u2014 either died out or moved south, joining the populations in southern France and the Iberian Peninsula that survived the glacial maximum in warmer refugia.<\/p>\n
The population that recolonized Britain after the glacial maximum \u2014 the Western Hunter-Gatherers, of which Cheddar Man is the best-studied British representative \u2014 were not the same people as the pre-glacial Britons.<\/p>\n
<\/p>\n
Ancient DNA analysis has shown that there was substantial population turnover in Europe during and after the Last Glacial Maximum: the earlier Paleolithic European populations were largely replaced by new populations expanding from the southern refugia as the ice retreated.<\/p>\n
Cheddar Man, in other words, was part of the second wave of modern humans to enter Britain, not the first.<\/p>\n
His population descended from people who had survived the glacial maximum in the south and then expanded north as the ice allowed.<\/p>\n
The very first modern Britons \u2014 whoever they were \u2014 preceded him by tens of thousands of years and left a different genetic signature.<\/p>\n
This is another layer of complexity in the already complex story of who the British were in the deep past.<\/p>\n
<\/p>\n
The Cultural Context: What Mesolithic Communities Did<\/p>\n
While archaeology cannot reconstruct the full cultural life of Cheddar Man’s community from the fragmentary evidence that Mesolithic sites provide, what is known about Mesolithic culture more broadly provides some sense of the world he inhabited.<\/p>\n
Mesolithic communities across Europe were not simply surviving on the margins of existence.<\/p>\n
They were culturally sophisticated, socially organized, and spiritually active.<\/p>\n
The evidence for this comes from multiple sources.<\/p>\n
The burial practices of the Mesolithic \u2014 including the unusual isolated burial of Cheddar Man \u2014 indicate that these communities had specific practices for treating the dead, practices that were differentiated from simple disposal and that probably carried spiritual or ceremonial significance.<\/p>\n
<\/p>\n
The communal burials more typical of the period, in which multiple individuals were interred together, suggest ongoing relationships between the living and the dead.<\/p>\n
Mesolithic people produced personal ornaments.<\/p>\n
Shell beads, animal tooth pendants, and other small objects have been found at Mesolithic sites across Europe.<\/p>\n
These ornaments indicate a concern for personal appearance and social identity that goes beyond bare survival.<\/p>\n
There is evidence of long-distance contact and exchange.<\/p>\n
Specific types of stone \u2014 flint, obsidian, and others \u2014 were used for tools at Mesolithic sites far from the geological sources of those materials, indicating that exchange networks connected communities across hundreds of kilometers.<\/p>\n
The specific evidence from Gough’s Cave includes the bones of the animals that Mesolithic people hunted and consumed there, the tools they made and lost or discarded, and the human remains.<\/p>\n
<\/p>\n
The cave was probably not a permanent settlement \u2014 more likely a seasonal camp or a special-purpose location \u2014 but it was used repeatedly by people who knew it, who returned to it, who found something in it that warranted the visit.<\/p>\n
What that something was, for Cheddar Man’s community, is not fully recoverable.<\/p>\n
But the cave clearly mattered to them in specific ways that left the traces that we can still read.<\/p>\n
The Broader Ancient DNA Picture: Europe In Motion<\/p>\n
The Cheddar Man finding is most fully understood in the context of the broader ancient DNA picture of prehistoric Europe, which has been assembled from hundreds of ancient specimens analyzed over the past decade.<\/p>\n
That picture shows a Europe in constant motion: populations arriving, populations departing, populations mixing and replacing each other across timescales from centuries to millennia.<\/p>\n
<\/p>\n
The Western Hunter-Gatherers like Cheddar Man were themselves relative newcomers to Europe \u2014 their population had expanded from the south after the Last Glacial Maximum, replacing or absorbing the earlier Paleolithic Europeans who had survived the glacial maximum in southern refugia.<\/p>\n
