According to evolution, the genus ''Australopithecus'' represents the earliest hominids, of which they say took place over 4,000,000 years ago. Of the several species in the genus, ''A. afarensis'' and ''A. africanus'' are the only ones considered – based on pelvic structure rather than brain capacity - with the exact positions of each in the evolutionary line still in dispute. | According to evolution, the genus ''Australopithecus'' represents the earliest hominids, of which they say took place over 4,000,000 years ago.
