The fossil record seems to indicate that Australopithecus is ancestral to Homo and modern humans. It was once assumed that large brain size had been a precursor to bipedalism, but the discovery of Australopithecus with a small brain but developed bipedality upset this theory. Nonetheless, it remains a matter of controversy as to how bipedalism ...
KNM-ER 406, the skull of a Paranthropus, brain volume estimated to 410 cm 3 with a visible sagittal crest and mild or intermediate post-orbital constriction but KNM-ER 37333, the skull of a Homo erectus, brain volume of 850 cm 3 with no visual sagittal crest and an almost not present or reduced post-orbital constriction.

Homo habilis is the oldest species given the designation Homo, by Leakey et al. in 1964. H. habilis is intermediate between Australopithecus afarensis and H. erectus, and there have been suggestions to re-classify it within genus Australopithecus, as Australopithecus habilis.
Australopithecus appeared and evolved before the genus Homo. The features of this hominid were a combination of apelike and human-like. Their arms were longer, which scientists believe was for ...
Its large, low and wide shape was completely distinct from the skulls of other known hominin species such as Neanderthals or Homo erectus, and different from the globe-shaped skulls of Homo ...
Homo erectus (/ ˌ h oʊ m oʊ ə ˈ r ɛ k t ə s / lit. ' upright man ') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years.It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire.
Homo (from Latin homō 'human') is a genus of great ape (family Hominidae) that emerged from the genus Australopithecus and encompasses only a single extant species, Homo sapiens (modern humans), along with a number of extinct species (collectively called archaic humans) classified as either ancestral or closely related to modern humans; these include Homo erectus and Homo neanderthalensis.
Around 2.07 million years ago, just before the arrival of P. robustus and H. erectus, A. africanus became extinct in the Cradle of Humankind. It is possible that South Africa was a refuge for Australopithecus until the beginning of major climatic variability and volatility, and, perhaps, competition with Homo and Paranthropus. [62]
