Australopithecus afarensis used stone tools

Shannon McPherron, Zeresenay Alemseged and colleagues working at the Dikika field site in Ethiopia have found evidence of stone tool use 3.39 million years ago [1]. That's 800,000 years earlier than the previous first-known tool use, and occurs during the existence of Australopithecus afarensis.

The evidence is a series of cutmarks and one percussion mark on two bovid bones. One is a piece of rib from a large "cow-sized" animal, the other a femur fragment from a smaller "goat-sized" bovid.

Of course, this comment:

The percussion marks on the femur demonstrate hominin use of a blunt stone to strike the bone, probably to gain access to the marrow

will have some creationist asshole jumping up and claiming that Cain hit Abel with a rock.
