A fossilized hominin leg shows gashes that were probably made by stone tools
A fossilized leg bone bearing cut marks made by stone tools might be the earliest evidence that ancient humans butchered and ate each other’s flesh.
Cuts, not bites? Pobiner had been examining a collection of fossils at the National Museums of Kenya in Nairobi — searching for animal bite marks — when she found unexpected linear markings a few millimetres long on the fossil of a tibia belonging to an unidentified hominin species. Previous evidence of butchery among hominins has been found at sites in Europe and Africa. This includes cuts on a hominin skull found in South Africa that dates to between 1.5 million and 2.6 million years ago, although there is disagreement among researchers about the age of the fossil and the marks’ origin.
