Graves Protection and Repatriation Act (NAGPRA) mandates that the remains be turned over to the tribes for burial. If he was not Native American, as some anthropologists believe due to the skeleton’s age, the remains can be kept, studied, and used for educational purposes.

Anthropologists who disagree with the claim that Kennewick Man is Native American have done so based on the morphology of the skull. The narrow brain casing and prominent forehead are more closely aligned with those living in coastal Asian locations, not Native Americans. However, a 13,000-year-old skeleton recovered in Mexico had a similar skull shape to Kennewick Man, but was found to be genetically related to Native Americans. If Kennewick Man was a Native American, he was one of the oldest in the region.
