This skeleton of a woman was found reclining on her left elbow, with fractures on the knees and possibly the left foot. The position of the hands suggests her wrists may have been bound. She was found surrounded by fish. (Image credit: Marta Mirazon Lahr)

Human remains reveal a rare instance of intergroup violence among prehistoric hunter-gatherers. Researchers found the remains of at least 27 people at a site in Kenya, including ten skeletons showing signs of blunt-force or sharp-force trauma to the head and/or neck.

The remains, dating to 9,500 – 10,500 years ago were found with no signs of deliberate burial, supporting the author’s view that this is an example of intergroup violence.
