An international team of researchers compared the genomes of 31 living native Americans, Siberians and people from Oceania with 23 ancient native American genomes to establish a timeline for the arrival and spread of Amerindian populations. They concluded that the first Americans arrived after about 23,000 years ago and diverged around 13,000 years ago into two populations. They also found no admixture of Polynesian or European genes, but did find some East Asian gene flow.Full StorySource
