A genetic analysis of a baby's remains dating back 11,500 years suggests that a previously unknown human population was among the first to settle in the Americas.
Scientists recovered the DNA from an infant — only a few weeks old when she died — buried at the Upward Sun River archaeological site in the interior of Alaska. Their data indicated that the baby belonged to a group of people who were genetically distinct from humans in northeastern Asia, the region that launched a migration into North America over a now-submerged land bridge across the Bering Strait.
However, the data also showed that this group differed genetically from the two known branches of ancestral Native Americans. The unexpected discovery of this Alaskan population offers a new perspective on the first people to settle in the Americas and presents a more detailed view of their migratory path, researchers explained in a...Read more...
