In 2015, Kennewick Man was confirmed to be Native American in a letter published in Nature. The 8,500-year-old skeleton discovered on 28 July 1996 at first seemed possibly of Caucasian or Asian origin. Native American tribes filed legal challenges to claim the remains as sacred to them. In 2004, a US Circuit Court of Appeals decision permitted scientists to continue their studies since there was at that time no evidence that the remains belonged to any modern tribe. But the new study identified a complete genome sequence found by Eske Willerslev and colleagues at the University of Copenhagen. It was related most closely to modern Native Americans, but didn't identify a particular tribe for repatriation of the remains.« Kennewick Man: The Scientific Investigation of an Ancient American Skeleton, by Douglas W.
