Members of Australopithecus are sometimes referred to as the "gracile australopithecines", while Paranthropus are called the "robust australopithecines". [ 10 ] [ 11 ] The australopithecines occurred in the Late Miocene sub-epoch and were bipedal , and they were dentally similar to humans, but with a brain size not much larger than that of ...
Debate exists as to whether some Australopithecus species should be reclassified into new genera, or if Paranthropus and Kenyanthropus are synonymous with Australopithecus, in part because of the taxonomic inconsistency. [7] [8] Furthermore, because e.g. A. africanus is more closely related to humans, or their ancestors at the time, than e.g.
They might be the product of Australopithecus garhi or Paranthropus aethiopicus, the two known hominins contemporary with the tools. [9] Genus Homo is assumed to have emerged by around 2.8 million years ago, with Homo habilis being found at Lake Turkana, Kenya.
However, it has been argued by some that Paranthropus is an invalid grouping and synonymous with Australopithecus, so the species is also often classified as Australopithecus robustus. Robust australopithecines—as opposed to gracile australopithecines—are characterised by heavily built skulls capable of producing high stresses and bite ...
Paranthropus is a genus of extinct hominin which contains two widely accepted species: P. robustus and P. boisei.However, the validity of Paranthropus is contested, and it is sometimes considered to be synonymous with Australopithecus.
Some, including Paranthropus, Ardipithecus, and Australopithecus, are broadly thought to be ancestral and closely related to Homo; [26] others, especially earlier genera, including Sahelanthropus (and perhaps Orrorin), are supported by one community of scientists but doubted by another. [27] [28]

Homo (from Latin homÅ '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.
