Homo habilis, known as 'handy man' is a species of the genus Homo which lived from approximately 2.33 to 1.4 million years ago, during the Gelasian Pleistocene period. The discovery and description of this species is credited to both Mary and Louis Leakey, who discovered the fossils in Tanzania between 1962 and 1964. Homo habilis was believed to be the earliest known species of the genus Homo, until 2010 with Curnoe’s research into Homo gautengensis.

In its appearance and morphology, Homo habilis is the least similar to modern humans of all species in the genus. Homo habilis was short and had disproportionately long arms compared with modern humans, but with a less protruding face than the australopithecines from which it is thought to have descended. Its cranial capacity was less than half of the size of modern humans. Fossil remains are often accompanied by primitive stone tools, hence the soubriquet 'handy man'. Generally, fossil remains demonstrate an australopithecine-like body with a more human-like face and smaller teeth.
 
Homo habilis has often been thought to be the ancestor of Homo ergaster, itself the ancestor of Homo erectus, but debates continue; was Homo habilis a direct human ancestor? Some argue Homo habilis was made up of fossil specimens of Australopithecus and Homo. Others argue that Homo habilis and Homo erectus were separate lineages from a common ancestor instead of Homo erectus being descended from Homo habilis [Spoor et al. 2007].
 
Homo habilis, although a scavenger rather than a master hunter, is thought to have mastered the Lower Paleolithic Olduwan tool set which utilized stone flakes. These stone flakes were more advanced than any tools previously used, and gave Homo habilis the edge it needed to prosper in hostile environments previously too formidable for primates. Whether Homo habilis was the first hominid to master stone tool technology remains controversial, as Australopithecus garhi, dated to 2.6 million years ago, has been found along with stone tool implements at least 100,000 to 200,000 years older than Homo habilis.
 
Homo habilis co-existed with other Homo-like bipedal primates, such as Paranthropus boisei, some of which prospered for many millennia. However, Homo habilis, possibly because of its early tool innovation and a less specialized diet, became the precursor of an entire line of new species, whereas Paranthropus boisei disappeared from the fossil record. Homo habilis may also have coexisted with Homo erectus in Africa for a period of 500,000 years [Urquhart 2007].
