DIFFUSIONE ED EVOLUZIONE DEI COMPORTAMENTI PRE-CULTURALI NEI PRIMATI NON UMANI.

About 2,5 million years ago, the lithic tools used by our ancestors (Homo habilis) for cutting the flesh of animal carcasses, appeared. The fossils of the first common ancestors of modern humans (Homo sapiens) date back to about 120 thousand years ago, when Homo neanderthalensis and other Hominidae were living at the same time in several places. Less than 50 thousand years ago, something happened which made human evolution a peculiar one. For example, some aspects of human culture developed rapidly, including the articulate language. All these forms of culture were deeply rooted in the material patrimony and in the cultural transmission of the non-human primates, the anthropoid monkeys. [ABSTRACT FROM AUTHOR]
