The genome of a famous 8,500-year-old North American skeleton, known as Kennewick Man, shows that he is closely related to Native American tribes that have for decades been seeking to bury his bones. The finding, reported today in Nature1, seems likely to rekindle a legal dispute between the tribes and the researchers who want to keep studying the skeleton. Yet it comes at a time when many scientists — including those studying Kennewick Man — are trying to move past such controversies by inviting Native Americans to take part in their research.
