Over the last decade, there have been a number of important fossil discoveries in Africa of what may be very early transitional ape/hominins, or proto-hominins.

In addition, the canine teeth were relatively short.One line apparently was adapted primarily to the food resources in lake margin grassland environments and had an omnivorous diet that increasingly included meat.Among them were our early human ancestors who started to make stone tools by this time.In the more open environments, bipedalism would very likely have been an advantage.By 2.5 million years ago, there were at least 2 evolutionary lines of hominins descended from the early australopithecines.He based this on the fact that the natural range of our nearest living relatives, chimpanzees and gorillas, is limited to Africa.

He concluded that we ultimately must have shared a now extinct common ancestor with those apes in Africa.

However, long before then, Dart recognized the importance of this find.

In 1925 he named it (literally "southern ape from Africa").

The primate fossil record for this crucial transitional period leading to australopithecines is still scanty and somewhat confusing.

However, by about 4.2 million years ago, unquestionable australopithecines were present.

The classification of Sahelanthropus has been the most in question.
