Homininae is a subfamily of Hominidae, which includes humans, gorillas and chimpanzees, and some extinct relatives; it comprises all those hominids, such as Australopithecus, that arose after the split from orangutans (Ponginae). Our family tree, which has 3 main branches leading to chimpanzees, humans and gorillas, could be more coherent than previously thought. Today there are several species of chimpanzee and gorillas (see Taxonomy) but only one human species remains, although several sub-species of humans appeared about a million years ago and still existed 30,000 years ago. The proposed evolutionary tree makes sense also when one considers brain size: there is a constant increase in brain volume along the human line, whereas the brain size remains almost unchanged in the chimpanzee and gorilla lines. Bipedalism seems to be an early acquisition in Homininae, which was present in early Australopithecines; it evolved independently into knuckle-walking in both chimpanzees and gorillas, and into efficient walking and running in modern humans. Evolution of family structure and sexuality is more complex and cannot be followed by paleontological studies of fossils. However physical characteristics and sexual dimorphism can provide some clues.
