Quizplus · Accepted Answer

The split between the later australopithecines and the ancestors of Homo took place sometime between 3 and 2 million years ago, during the Pliocene epoch. This is evidenced by the appearance of the earliest known Homo fossils around 2.8 million years ago and the disappearance of the later australopithecines from the fossil record around 2 million years ago. Option A is too early for the split, option B is incorrect as there is no evidence of Australopithecus garhi discovering fire, option C is incorrect as there is evidence of a split occurring, and option D is too late for the split.
