Australopithecus is a member of the subtribe Australopithecina, [4] [5] which sometimes also includes Ardipithecus, [6] though the term "australopithecine" is sometimes used to refer only to members of Australopithecus. Species include A. garhi, A. africanus, A. sediba, A. afarensis, A. anamensis, A. bahrelghazali, and A. deyiremeda.
Orrorin had smaller teeth relative to body size and the enamel was thicker. [5] The upper canines contain a mesial groove which differs from both Australopithecus and Ardipithecus. [5] The canines, in general, were very ape-like but were much smaller. [5] Like modern humans, Orrorin had post-canines that were smaller and were microdont. [5]
Presently, it appears that A. garhi has the potential to occupy this coveted place in paleoanthropology, but the lack of fossil evidence is a serious problem. Another problem presents itself in the fact that it has been very difficult to assess which hominid [now "hominin"] represents the first member of the genus Homo .

Australopithecus garhi was discovered by Tim White in the Bouri Peninsula area of Middle Awash. It was announced in 1999. [8] Au. Garhi has a holotype of a fragmented skull. The skull has all teeth but the left second and third molars, and additionally contains fragments of the frontal, parietal, and maxilla. Similarities in the cranial ...
Studies of premolar size in hominid species that predate Australopithecus afarensis show long, uni-cuspid teeth at the P 3 location, while species dated after A. afarensis have been shown to have wider, bicuspid teeth at the same location, which is hypothesized to show the beginnings of canine to premolar evolution in hominids.

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.
