Australopithecus garhi is a species of australopithecine from the Bouri Formation in the Afar Region of Ethiopia 2.6–2.5 million years ago (mya) during the Early Pleistocene. The first remains were described in 1999 based on several skeletal elements uncovered in the three years preceding.
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.
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 .

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.
The canines and incisors fall into the size range of Au. Afarensis, but the premolars and molars are comparatively very large. Pa. Boisei is the only hominin with larger post canines. Au. Garhi additionally has a thinner plate and cheekbones that flare less than usual. Additionally, Homo has wear patterns in cheek teeth like Au. Garhi.
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.
Australopithecus garhi was using stone tools at about 2.5 Ma. 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.
