Concernant l Homo Habilis,je te conseille de lire cet article :
BerNew fossils of the same species unearthed in the late 1980s were to completely change this view. Some researchers, such as Bernard Wood and C. Loring Brace, who relied on those newly-found fossils, stated that Homo habilis (which means "skillful man," that is, man capable of using tools), should be classified as Australopithecus habilis, or "skillful southern ape," because Homo habilis had a lot of characteristics in common with the austalopithecine apes. It had long arms, short legs and an ape-like skeletal structure just like Australopithecus. Its fingers and toes were suitable for climbing. Their jaw was very similar to that of today's apes. Their 600 cc average cranial capacity is also an indication of the fact that they were apes. In short, Homo habilis, which was presented as a different species by some evolutionists, was in reality an ape species just like all the other Australopithecines.
