Asian migration hypothesis

A little about the video
Ann Gibbons Science Magazine Vol. New genetic data suggests that the earliest Americans came from Asia in one or two waves-not more-challenging an earlier synthesis of linguistic, dental, and genetic data. Six years ago, D. Andrew Merriwether was a master's student in the lab of geneticist Douglas Wallace at Emory University in Atlanta, learning to use genes to trace the ancestry of native American peoples.

Migration from Asia - Vocabulary List :

Recent arguments connecting Na-Dene languages of North America with Yeniseian languages of Siberia have been used to assert proof for the origin of Native Americans in central or western Asia. We apply phylogenetic methods to test support for this hypothesis against an alternative hypothesis that Yeniseian represents a back-migration to Asia from a Beringian ancestral population. We coded a linguistic dataset of typological features and used neighbor-joining network algorithms and Bayesian model comparison based on Bayes factors to test the fit between the data and the linguistic phylogenies modeling two dispersal hypotheses. Our results support that a Dene-Yeniseian connection more likely represents radiation out of Beringia with back-migration into central Asia than a migration from central or western Asia to North America.

For more than half a century, the prevailing story of how the first humans came to the Americas went like this: Some 13, years ago, small bands of Stone Age hunters walked across a land bridge between eastern Siberia and western Alaska, eventually making their way down an ice-free inland corridor into the heart of North America. In recent years, however, that version of events has taken a beating, not least because of the discovery of archaeological sites in North and South America showing that humans had been on the continent 1, or even 2, years before the supposed first migration. Supporting that idea are archaeological sites along the West Coast of North America that date back 14, to 15, years. Now our understanding of when people reached the Americas—and where they came from—is expanding dramatically. The emerging picture suggests that humans may have arrived in North America at least 20, years ago—some 5, years earlier than has been commonly believed.
