present in the 3.2-million-year-old Australopithecus fossil (Lucy)?
Lucy was a bipedal hominid with a brain size similar to that of modern humans, demonstrating that A. bipedality and larger brains evolved together.
Stone tools were found in the same rock layer where Lucy was found, showing that members of this B. species were making and using tools 3.2 million years ago.
Lucy was a bipedal hominid, and its discovery provided evidence that bipedality preceded the C. evolution of a larger brain size and extensive tool use.
Lucy had a large brain, but there is no evidence that it used tools or that it walked mostly on two legs.
