A researcher found what appear to be cut marks on the bone of a human ancestor. I was really not expecting to find these sorts of cut marks." Almost all of the bone's marks could be classified as cut marks with a high degree of confidence, Pobiner said. Not all cut marks mean cannibalismTwo marks (5 and 6) were identified as tooth marks, and the rest were identified as cut marks. Pobiner hopes the findings will inspire other researchers to return to existing collections to look for more cut marks.
