Homo habilis

An extinct species of early humans, known from fossils found in eastern Africa and often considered to be the first member of the genus Homo. It is associated with stone tools of the Oldowan culture. Homo habilis existed between about 2.5 and 1.6 million years ago and overlapped with late australopithecines and other hominids whose relationship to each other and to the later Homo erectus are uncertain.
