writes "The genome of a 5,000 year old man from Greenland has been sequenced from scalp hair remains. He belonged to the now-extinct Saqqaq who are genetically more closely related to east Asians than to contemporary Native North Americans. Although both contemporary Inuit and the extinct Saqqaq migrated from Siberia across the Bering Straits, the Saqqaq migration was a much later one (5,000-10,000 years ago, compared with 20,000 for the Inuit). All that is left of the Saqqaq today are a few archaeological sites in Greenland. Genetic analysis revealed that "Inuk" was stocky, possibly with a receding hairline, had a cold-adapted metabolism, A+ blood type, and possibly a rather bad haircut.
The hair sample form which the DNA was sequenced was excavated in 1986 and was archived at the National Museum of Denmark. It was only recently rediscovered by a research team who spent a fruitless 3 months at Saqqaq sites looking for hair samples for genome analysis."Link to Original Source
