The founding population of the Americas, as described in the genetic literature, is similarly a statistical construct — an inferred ancestral population that is postulated because it is the best-fitting ancestor for the observed diversity of Native American genomes.

It was not a single community in the social sense.

It was a collection of people who were related to each other more closely than to other human populations and who, together, represent the demographic source from which all later Native American populations descended.
