This dispersal produced the diverse populations of the Western Hemisphere, all of whom trace their ancestry to the Beringian founding.

Within the broader pattern of Native American ancestry, specific patterns of differentiation and relatedness among different regional populations reflect the specific demographic histories of those populations.

The northwest Coast peoples — the Tlingit, Haida, Tsimshian, and others — show specific genetic patterns that reflect both their shared founding ancestry and the specific history of the coastal population since its establishment.

The Shuká Káa analysis contributed to characterizing this specific coastal population history by providing an ancient-genome data point from a specific geographic location at a specific early date.

Placing Shuká Káa’s genome in the broader population-genetic framework — comparing it to ancient and modern genomes from across the Americas and from northeastern Asia — established his position within the genealogy of Native American populations and confirmed his specific relationship to the later coastal peoples.
