It supported the conclusion that the founding of the Americas was more complex and internally diverse than simple models had suggested, but that it was essentially a single founding event from which all Native American peoples ultimately descend.

That conclusion matters for the people who are descended, in the broad biological sense, from the founding population of the Americas — the Indigenous peoples of the hemisphere, the millions of living people whose ancestors have been here since the founding and who have built the cultures, languages, and societies that constitute the human history of two continents.

For those people, the finding that Naia was genetically part of their ancestral lineage is one more piece of evidence for something they have never doubted: they are ancient, they are rooted here, and their connection to this hemisphere goes back to the very beginning of human presence in it.

Naia’s haplogroup is a small thread in the vast weave of that history.
