SOME Native Americans Have West Eurasian Origins

The arm bone of a three-year-old boy from the Mal’ta site near the shores of Lake Baikal in south-central Siberia (map) yielded what may be the oldest genome of modern humans ever sequenced.

A second individual genome sequenced from material found at the site and dated to 17,000 years ago revealed a similar genetic structure.

It also provided evidence that humans occupied this region of Siberia throughout the entire brutally cold period of the Last Glacial Maximum, which ended about 13,000 years ago.
