They found that while most Native American populations descend primarily from one migration, there were two later ones that also made a significant genetic contribution.The first migration, that led to the majority of Native American populations, was of a single group called the “First Americans” that crossed from Asia to America in a land bridge called Beringia, that existed during the ice ages more than 15,000 years ago, say the researchers, whose efforts were co-ordinated by Professor Andres Ruiz-Linares of the department of Genetics, Evolution and Environment at University College London (UCL) in the UK.The later migrants probably arrived in boats, after the land-bridge disappeared at the end of the ice ages.In a press statement, Ruiz-Linares explains that for years there has been a debate about whether the settlement of the Americas came from one or several migrations out of Siberia.“But our research settles this debate: Native Americans do not stem from a single migration. Our study also begins to cast light on patterns of human dispersal within the Americas,” he adds.The findings confirm what linguist Joseph Greenberg proposed in 1986. From studying language differences among Native Americans, he said the Americas must have been populated in three waves of migration.For the study, the researchers searched more than 300,000 specific DNA markers or “snips” (SNPs, Single Nucleotide Polymorphisms) from 52 Native American and 17 Siberian groups, looking for similar and different patterns of genes.Co-author David Reich, Professor of genetics at Harvard Medical School in the US, says they found evidence of at least three “deep lineages”:“The Asian lineage leading to First Americans is the most anciently diverged, whereas the Asian lineages that contributed some of the DNA to Eskimo-Aleut speakers and the Na-Dene-speaking Chipewyan from Canada are more closely related to present-day East Asian populations,” says Reich.It appears that 50% of the DNA of Eskimo-Aleut speakers comes from the First Americans, while in the Na-Dene-speaking Chipewyans, 90% of their DNA descends from the First Americans.</blockquote>
