The 31,000-Year-Old Children’s Teeth Found Above The Arctic Circle — And The DNA Test That Revealed A Lost Ice Age Population Connected To Native American Origins

The other, contributing roughly a third to forty percent of the ancestry of most Native American populations, was something different: something more closely related to the ancient populations of Western Eurasia.

This Western Eurasian-related component had been puzzling.

It did not fit simple models of a single migration from East Asia across Beringia.

It suggested that somewhere in the deep history of the ancestral Native American population, there had been mixing between East Asian-related peoples and a population with Western Eurasian affinities.

Where had this mixing happened?

When?

With whom?

The answer, or a major part of it, had emerged from a discovery made before the Yana DNA study: the Mal’ta Boy, an ancient individual found near Lake Baikal in southern Siberia, dating to roughly 24,000 years ago.
