Nine cut marks on a 1.45 million-year-old hominin bone suggest another hominin, possibly of the same species, slashed the bone to strip the flesh and eat it.
About 1.45 million years ago, ancient human relatives ate one of their own, chowing down on meat from a shinbone, according to cut marks that constitute the oldest decisive evidence that our relatives butchered and made a meal out of one another, a new study finds.
"The information we have tells us that hominins were likely eating other hominins at least 1.45 million years ago," study first author Briana Pobiner, a paleoanthropologist at the Smithsonian's National Museum of Natural History in Washington, D.C., said in a statement.
Pobiner and her colleagues also detected two dents in the bone, which they identified as bite marks from a big cat — possibly belonging to one of the saber-toothed cat species living in eastern Africa at the time. But they found no human tooth marks on the fossil.
