Evidence of Cannibalism Among Early Human Ancestors 1.45 Million Years Ago

Researchers have discovered the oldest evidence of humans' close evolutionary relatives butchering and likely eating one another. The study describes nine cut marks on a 1.45 million-year-old left shin bone from a relative of Homo sapiens found in northern Kenya. Analysis of 3D models of the fossil's surface revealed that the cut marks were dead ringers for the damage inflicted by stone tools. This is the oldest instance of this behavior known with a high degree of confidence and specificity.
