Homo Habilis
Traits, Tools, & Facts
Homo habilis, (Latin: “able man” or “handy man”) extinct species of human, the most ancient representative of the human genus, Homo. Homo habilis inhabited parts of sub-Saharan Africa from roughly 2.4 to 1.5 million years ago (mya). In 1959 and 1960 the first fossils were discovered at Olduvai Gorge in northern Tanzania. This discovery was a turning point in the science of paleoanthropology because the oldest previously known human fossils were Asian specimens of Homo erectus. Many features of H. habilis appear to be intermediate in terms of evolutionary development between the relatively primitive Australopithecus and the more-advanced Homo species.

The first confirmed remains found at Olduvai consist of several teeth and a lower jaw associated with fragments of a cranium and some hand bones. As more specimens were unearthed at locations such as Koobi Fora in northern Kenya, researchers began to realize that these hominins were anatomically different from Australopithecus, a genus of more-apelike creatures whose remains had been found at many African sites. Formal announcement of the discoveries was made in 1964 by anthropologists Louis S.B. Leakey, Phillip Tobias, and John Napier. As justification for designating their new creature Homo rather than Australopithecus, they described the increased cranial capacity and comparatively smaller molar and premolar teeth of the fossils, a humanlike foot, and hand bones that suggested an ability to manipulate objects with precision—hence the species name Homo habilis, or “handy man.” Furthermore, simple stone tools were found along with the fossils. All these characteristics foreshadow the anatomy and behaviour of H. erectus and later humans, making H. habilis extremely important, even though there are few remnants of it.
