Homo habilis ("handy man") is a species of the genus Homo, which lived from approximately 2.5 million to 2.0 million years ago. The definition of this species goes back to Louis Leakey who found fossils in Tanzania, East Africa, in 1964. Homo habilis is arguably the first species of the Homo genus to appear. In its appearance and morphology, H. habilis was the least similar to modern humans of all species to be placed in the genus Homo (except possibly Homo rudolfensis). Homo habilis was very short and had disproportionately long arms compared to modern man. It is thought to have descended from a species of Australopithecine hominid. It may have had a more immediate ancestor in the form of the somewhat more massive and ape-like, Homo rudolfensis. Homo habilis had a brain slightly less than half of the size of modern man. These early human ancestors were small, on average standing no more than 1.3 m tall.

Homo habilis shared the earth with many other Homo-like bipedal primates, such as Paranthropus boisei, which were also highly successful, some prospering for many millennia. However, H. habilis, with its early tool innovation and less specialized diet, proved to be a precursor of an entire line of new species, whereas Paranthropus boisei and its relatives disappeared from the later fossil record.

Homo habilis is thought to have mastered the Oldowan era (Early Paleolithic) tool case which utilized stone flakes. Though these stone flakes were primitive by human standards, they were more advanced than any tools that had ever previously existed, and they gave H. habilis the edge it needed to prosper in hostile environments previously too formidable for primates. However, H. habilis was not the master hunter that its descendants proved to be, as there is ample fossil evidence that H. habilis was a major staple in the diet of large predatory animals such as DinofelisDinofelis is a large cat that lived in Europe, Asia, Africa and North America approximately 5-1. 5 million years ago. Its existence coincides in part with that of Machairodus which lived 13-2 million years ago. Dinofelis is an ancestor of the prehistoric barlowi, a large predatory catFelinae Pantherinae Acinonychinae All cats are members of the family Felidae . The felines are the most strictly carnivorous of the nine families in the order Carnivora. The cats' closest relatives are thought to be the other families in their branch of t similar to a leopardThis page is about the animal. For the tank, see Leopard MBT. For the coin, see English coin Half Florin or Leopard. Leopards Panthera pardus are one of the four 'big cats' of the genus Panthera''. The others are the Lion, Tiger, and Jaguar. They range in. H. habilis used tools primarily for scavenging, such as cleaving meat off of carrion, rather than defence or hunting.

Homo habilis is thought to be the ancestor of the lankier and more sophisticated, Homo ergasterHomo ergaster ("workman man") is an extinct hominid species (or subspecies, according to some authorities) which arose in Africa some 1. 9 million years ago. ergaster is sometimes categorized as a subspecies of Homo erectus''. It is currently in contentio, which in turn gave rise to the more human appearing species, Homo erectusHomo erectus ("upright man") is a hominid species that is believed to be an ancestor of modern humans. The species is found from the middle Pleistocene onwards. It had fairly modern human features, with a larger cranial capacity than that of Homo habilis'. There is debate over whether H. habilis is a direct human ancestor, and over how many known fossils are properly attributed to the species.

There is little evidence that Homo habilis controlled fire, buried its dead, hunted cooperatively, used language (any more advanced than gestures) or studied its environment in the manner of its later descendants.
