NEW YORK (GenomeWeb) – Analysis of ancient DNA has allowed two groups of researchers to trace the movements of ancient human populations that lived in Siberia and those who moved from there into the Americas.
Humans first reached Siberia more than 40,000 years ago during the late Pleistocene, an ice age that occurred from about 126,000 years ago to about 11,700 years ago when Beringia connected Siberia to the Americas.
