Australopithecus garhi (2.5 million years ago)
Australopithecus garhi may represent an evolutionary
link between the genera of Australopithecus and Homo. Circumstantial
evidence suggests that A. garhi may have been the earliest tool user.
Antelope fossils excavated from the same site as A. garhi show cut marks
made by a stone tool; both the hominid and antelope fossils are dated at 2.5
million years old. The earliest stone tools, thought to be 2.6 million years
old, were found nearby in Gona, Ethiopia.
