The person skillful (Homo habilis) represented a transitional look between the Australopithecus and the person orthograde, he lived in the territory Africa 2.5-1.5 million years ago. This representative of a sort is least of all similar to the modern person, his primitive lines lead some experts to a conclusion about an exception of this view from the sort Homo.
Building and morphology
The person skillful was no more than 130 cm in height, he possessed disproportionately long hands. Its weight was about 30-50 kg, and the volume of a brain was twice less, than at the modern person. It differed from Australopithecuses in the large volume of a cranium and the structure of a basin which provided more perfect way of movement by means of legs.
The skull of the person skillful was expanded in parietal and occipital and infraorbital areas. It already had structures of a brain necessary for emergence of the speech frontal and parietal shares increased. In comparison with the Australopithecus, the size of teeth Homo habilis decreased, and enamel became thinner. If to judge in structure jaws, then this representative of a sort preferred meat food, but not vegetable.
The leg of the person skillful had 5 bones of a foot, 5 phalanxes of fingers, an ankle and a calcaneal bone. On the building the leg was primitive, but nevertheless human. The structure of a brush combined as the progressive lines necessary for creation of tools and power capture, and adaptation traces to a lasagna on trees. Expansion of nail phalanxes testifies about formation of manual small pillows as tactile device.
Social organization
One of the main criteria of belonging to the sort Homo — creation of tools what requires the large volume of a brain and change in the structure of a brush. The person skillful manufactured tools which were the stones split for the purpose of receiving the cutting edge. Homo habilis call the creator of pebble culture, however his tools bear traces of insignificant processing, for their creation from only 3 to 10 blows were used. Such tools were more perfect, than those that were applied earlier. They gave to the person skillful an opportunity to survive in conditions which were before hostile for primacies. Experts believe that the social organization and intelligence of Homo habilis were more complex, than at Australopithecuses. Though the person skillful also used tools, unlike modern people, he was not a good hunter and often fell prey of large animals what fossil remains testify to. By means of tools, meat from bones which left predators separated. As a rule, tools of the person skillful were not used for attack and protection.
