We already knew the broad strokes of this story : Ancient humans from Siberia probably crossed the Bering land bridge into Alaska sometime before 15,000 years ago.
Today’s study, published in the journal Nature , helps fill in more details about the genetic origins of Native Americans — and reveals a newly discovered group of ancient people.
About a meter beneath the hearth, two infants were also buried in a circular pit filled with grave goods, including blades and hunting tools.
Now, a team of scientists led by ancient DNA specialist Eske Willerslev at the University of Copenhagen has sequenced the complete genome of the 6-week-old infant — named “Xach’itee’aanenh T’eede Gaay” (sunrise girl-child) by the local indigenous community.
Adding this new clue to computer simulations of the peopling of North America helped the team flesh out the timeline — which they now suspect goes something like this: about 36,000 years ago in northeast Asia, the ancestors of modern Native Americans began splitting off from ancestral Asians.
