Homo habilis

Homo habilis (literally “skilful man”) is one of the Homo which lived there are roughly 2,5 to 1,8 million years in Eastern and southern Africa.

The definition of this species was made by Louis Leakey in 1964, following the discovery of Fossile S in Tanzania.

Homo habilis and the bipédie

The Homo habilis had a perfect command of the set up posture, even if this one does not appear with him. On the other hand, its short rear limbs did not make a as large walker of it as the Homo ergaster , appeared later on. Its aspect remained very antiquated.

The species presented a fort sexual Dimorphisme, the females being much smaller than the males.

Homo habilis , inventor of the tool?

Homo habilis is contemporary older industries of cut stone, named Oldowayen born. Those comprise simple objects generally cut on only one face to make a tool (Chopper) or to obtain glare S edges. These tools were to enable him to cut out pieces of meat or to break bones. But Homo habilis coexisted with certain robust forms of Australopithèque S, the Paranthrope S. Certains scientists consider that those were also able to manufacture stone tools cut.

A very developed cranial capacity

The Homo habilis has a cranial capacity ranging between 550 and 680 cm ³. It measures approximately 1,20à 1,50 m and weighs from 30 to 40 kg. The study of its teeth shows reduced canines and developed incisors what shows that the Homo habilis was omnivorous, it is probable that it was vulture and not hunter. Its cranium is a little bulkier than that of a chimpanzee

Paleopathology

The study of the remainders of a Homo habilis going back to 1,8 million years showed that he suffered from Arthrose and of Rhumatisme S.
