The Kolyma1 individual, 20,000 years after Yana, shows a detectable component of ANS-related ancestry — the blue tinge is still visible in the chemical analysis, even if it has been significantly diluted.

And then, in the genomes of Native Americans, there is a component of ancestry that traces through this chain — through the Ancient North Siberians, through the Kolyma-like populations, through the mixing and movement of thousands of years of Siberian prehistory — to the founding of the Americas.

The specific pathway is still being refined by ongoing research.

The Yana children were not the direct ancestors of Native Americans.

The population that eventually crossed into the Americas was a mosaic — primarily East Asian-related ancestry, with a component that traced back to the ANS lineage through the kinds of admixture visible in the Kolyma1 individual.
