DNA Reveals History of Vanished "Paleo-Eskimos"

An anonymous reader writes The earliest people in the North American Arctic remained isolated from others in the region for over 4,000 years before vanishing around 700 years ago, new analysis shows. The study also reveals that today's Inuit and Native Americans of the Arctic are genetically distinct from the region's first settlers. "A single founding population settled, and endured the harsh environmental conditions of the Arctic, for almost 5,000 years — during which time the culture and lifestyle changed enough to be represented as distinct cultural units," explained Dr Maanasa Raghavan, first author of the new paper.
