Homo habilis, better known as the “jack-of-all-trades man” is one of the first species to diverge in the genus Homo. The larger cranial size (average cranial capacity of approximately 610 cc) accompanied by the complexity and reduction of the face (Poirer, 2005) are two characteristics that appear for the first time in Homo habilis and are unique compared to previous genera such as Australopithecus . The found remains of Homo habilis are typically found from the late Pliocene, 1.7-2.5 million years ago (2005) and include OH 62.OH 62, Homo habilis, is a fossil, dating back to 1.8 million years ago, established by Tim White in 1986 at the Olduvai Gorge site in Tanzania (Johanson, 1996; Ruff 2009; Walker, 1993). Olduvai Gorge has been a popular site for finding not only remains of Australopithecus species, but also remains of hominid species. 302 pieces of fragmented bones of cranial and post-cranial remains were found at the site and are the first remains found in which Homo habilis upper and lower limb fragments are associated with an individual (Ash, 2011; Dunsworth 2002; Johanson, 1996 ; By putting together 32 parts of the found bone, the jaw began to represent Homo habilis, with more gracile and orthognathic features (compared to Australopithecus) and maintained more alveolar prognathism (Poirer, 2005) than modern humans upper jaw appeared to represent a fossil of Homo habilis, the remaining bone fragments began a debate as to which taxonomic group OH 62 belonged to. Portions of the skull, the proximal half of the left femoral shaft and neck, as well as a small proximal portion of the right tibia, most of the right humeral shaft, right radial shaft and most of the ulna. (Ash, ...... middle of the paper ...... and the long length note of arms relative to legs, it can be assumed that OH 62 was still capable of arboreal life, and continued to forage in Through this behavior, it can be assumed that OH 62 continued to forage in trees as a way to gather food, as well as protect itself from other predators (Line, 2005; Poirer, 2005; Wood, 1999). a significant discovery and addition to the fossil record, supporting the understanding of human evolution and the beginning of hominid divergence. Not only do the limb proportions of OH 62 explain the nature of bipedalism in early hominids, but they show a transition from Australopithecus. to early Homo Since femur length is only an estimate, the taxonomic group status of OH 62 will continue to be a matter of debate, however at present OH 62 will remain in the genera of Homo habilis..
