"Genetic evidence published today in Nature is the first to show that all Native Americans can trace their ancestry back to a single migration event that happened at the tail-end of the last Ice Age. The evidence—gleaned from the full genomic profile of the six-week-old girl and the partial genomic remains of another infant—suggests the continent’s first settlers arrived in a single migratory wave around 20,900 years ago. But this population then split into two groups—one group that would go on to become the ancestors of all Native North Americans, and another that would venture no further than Alaska—a previously unknown population of ancient North Americans now dubbed the “Ancient Beringians.”
