The 8,800-Year-Old Man Found 1,000 Feet Inside A Colorado Cave — And The DNA Test That Linked Him To A Native American Founder Lineage
We do not know whether the community was primarily a mountain-adapted group or whether it spent part of the year at lower elevations and moved into the high country seasonally.
What we can infer, from the general picture of early Holocene population in the Americas, is that the communities of this period were small by the standards of later North American prehistory.
Population densities in the early Holocene Americas were low — the continent was still thinly settled, and the specific ecological knowledge and technological capabilities needed to exploit different environments fully were still being developed.
Groups were probably numbering in the tens or perhaps low hundreds of individuals, highly mobile, moving through large territorial ranges in response to seasonal resource availability.
