Previously, genetic analysis had indicated that the ancestors of Native Americans left Siberia to migrate across ancient Beringia (the strip of land that once connected Asia and what's now Alaska) about 25,000 years ago, but the earliest evidence of human habitation on North America dates to 15,000 years ago. With ice covering much of Alaska, the ancestors of Native Americans might've lived in Beringia for about 10,000 years before moving on. Now linguistic evidence may help support that theory. A pair of linguistics researchers, Mark Sicoli and Gary Holton, recently analyzed languages from North American Na-Dene family (traditionally spoken in Alaska, Canada and parts of the present-day U.S.) and the Asian Yeneseian family (spoken thousands of miles away, in central Siberia), using similarities and differences between the languages to construct a language family tree. As they note in an article published today in PLOS ONE, they found that the two language families are indeed related-and both appear to descend from an ancestral language that can be traced to the Beringia region. Both Siberia and North America, it seems, were settled by the descendants of a community that lived in Beringia for some time. In other words, Sicoli says, "this makes it look like Beringia wasn't simply a bridge, but actually a homeland-a refuge, where people could build a life."
