Homo habilis- This species, one of the genus Homo’s earliest members, has a slightly larger braincase and smaller face and teeth than Australopithecus or other older hominin species. It does, however, have certain ape-like characteristics, such as large limbs and a fairly prognathic face.
Homo erectus- H. erectus was a medium-sized human who walked upright. The forehead was receding, the nose, jaws, and palate were wide, and the braincase was low. In comparison to modern humans, the brain was smaller and the teeth were larger.
Neanderthal man- Neanderthals possessed a long, low head (as opposed to modern humans’ more globular skull) with a noticeable brow ridge above their eyes. Their features were likewise distinct. A large, wide nose dominated the centre area of the face, which protruded forward.
