HUMAN EVOLUTION 'AI'

The species that were attributed to the genus australopithecus (which means "southern monkey"), which almost certainly lived in Tanzania and Ethiopia for at least 3 million years, until they became extinct about 1 million years ago, are divided into three different genera (some texts do not yet recognize the genus Paranthropus, they refer P. tugenensis to the genus Orrovienerin and other hypothesized taxonomies). The hominina belonging to them were not thought to be capable of making tools, but only of using pebbles for simple purposes such as breaking or hitting. They lived in groups, hunted small animals and collected eggs and seeds.

Later worked stone artefacts similar to those of Olduvaian technology were found together with A. garhi fossils and dated to be between 2.5 and 2.6 million years old.[5] These tools appear older than those used by 'Homo habilis[5], considered a possible direct ancestor of modern humans, and are rather crude, still lacking the technique that would have appeared in the later Olduvaian and Acheulean forms. In the area of ​​the Auasc river in the desert depression of the Ethiopian Afar, Jean de Heinzelin, of the Institut Royal des Sciences Naturelles de Belgique, discovered numerous animal remains with evident signs left by tools. It is thus hypothesized that A. garhi already had those prerogatives of the Homo genus, such as the systematic slaughter of prey, which were not thought to exist before 1.8 million years ago. Further findings in Bouri, also in Ethiopia, revealed around 3,000 stone tools dated to around 2.5 million years ago
