Ancient humans probably ate each other

A carved-up leg bone might be the earliest evidence that ancient humans butchered and ate each other’s flesh. The 1.45-million-year-old hominin bone features cuts similar to the butchery marks made by stone tools found on fossilised animal bones. The scrapes are located at an opportune spot for removing muscle, suggesting that they were made with the intention of carving up the carcass for food. It isn’t possible to say whether this is an example of cannibalism, because the bone belongs to an unidentified hominin species.
