Study: Native Americans have West Eurasian origins

Native Americans have closer genetic ties to people in Eurasia, the Middle East and Europe than previously believed, according to new research on a 24,000-year-old human bone.
Genome sequencing on the arm bone of a 3-year-old Siberian boy known as the "Mal'ta Boy," the world's oldest known human genome, shows that Native Americans share up to one-third of their DNA with people from those regions, said Kelly Graf, a research assistant professor at the Department of Anthropology at Texas A&M University and a member of the international research team.
