Dart assumed these broken animal bones, teeth and horns were used by Au. africanus as weapons; however, in the 1970s and 1980s, other scientists began to recognize that predators such as lions, leopards, and hyenas were instead responsible for leaving these broken animal bones.

Did Australopithecines eat meat?
The ancestral Australopithecus consumed a wide range of foods , including, meat, leaves and fruits. This varied diet might have been flexible to shift with food availability in different seasons, ensuring that they almost always had something to eat.
Did Lucy use stone tools?
The bones date to roughly 3.4 million years ago and provide the first evidence that Lucy's species, Australopithecus afarensis, used stone tools and consumed meat. The research is reported in the August 12th issue of the journal Nature. The two bones found in Dikika, Ethiopia, clearly show traces of cuts and blows.
What was the first tool?

Was the first tool maker?
THE GIST. – Until now, the earliest tool-maker was thought to be Homo habilis . ... sediba discovered in South Africa in 2008 suggests these creatures who roamed the Earth 1.9 million years ago were crafting tools even earlier, and could be the first direct ancestor of the Homo species.

Why did Louis and Mary Leakey choose Olduvai Gorge?
Paleoanthropologist Louis Leakey, with wife Mary Leakey, established an excavation site at Olduvai Gorge to search for fossils . The team made unprecedented discoveries of hominids millions of years old linked to human evolution, including H. habilis and H. erectus.
What was the first hominid to use tools?
Tool users. Current anthropological thinking is that Oldowan tools were made by late Australopithecus and early Homo. Homo habilis was named “skillful” because it was considered the earliest tool-using human ancestor.
