Several specimens with insecure species identification were assigned to H. habilis, leading to arguments for splitting, namely into "H. rudolfensis" and "H. gautengensis" of which only the former has received wide support. Like contemporary Homo, H. habilis brain size generally varied from 500 to 900 cm 3 (31–55 cu in).
Genus Homo is assumed to have emerged by around 2.8 million years ago, with Homo habilis being found at Lake Turkana, Kenya. The delineation of the "human" genus, Homo, from Australopithecus is somewhat contentious, for which reason the superordinate term "hominin" is often used to include both.

OH 7 (Olduvai Hominid № 7), also nicknamed "Johnny's Child", [1] is the type specimen of Homo habilis. The fossils were discovered on November 4, 1960 in Olduvai Gorge, Tanzania, by Jonathan and Mary Leakey. The remains are dated to approximately 1.75 million years, and consist of fragmented parts of a lower mandible (which still holds ...
The few Australopithecus boisei remains, which include the skull, a thigh bone fragment, and several teeth, were found distributed throughout Beds I and II, which dates them in the range 1.1 to 2 mya. The more common remains of Homo habilis were found in Bed I and the lower portion of Bed II, which makes them contemporaries of Australopithecus ...
The remains of Homo erectus have been found on the Indonesian island of Java and elsewhere in Asia as well as Africa. ... small-bodied hominins such as Homo habilis, only known from Africa, others ...
The researchers found that the Dmanisi hominins "cannot unequivocally be referred either to H. habilis or to H. erectus" and that there, in regards to early Homo, was a "continuum of forms"; Skull 5 appears to share many primitive features with H. habilis whereas Skull 1, with the largest brain, is more similar to African H. ergaster/H. erectus ...
Already before 2010, there were suggestions that H. habilis should not be placed in the genus Homo but rather in Australopithecus. [43] [44] The main reason to include H. habilis in Homo, its undisputed tool use, has become obsolete with the discovery of Australopithecus tool use at least a million years before H. habilis. [38]
