Primitive people are representatives of numerous human-like species that lived before the invention of writing, after which there is an opportunity for historical research based on the study of written sources. Man has gone a long way in evolution from primitive apes, Australopithecus, Homo habilius, Homo erectus, to Homo sapiens.
Human evolution is 5 million years old. The oldest ancestor of modern man, Homo habilius, appeared in East Africa 2.4 million years ago. He could make fire, build simple shelters, collect plant food, process stone, and use primitive stone tools. Many stone tools of various shapes and sizes were found in the Olduvai gorge (Tanzania).
A skilled man lived only in Africa. The first to leave Africa and enter Asia, and then Europe, was Homo erectus. It appeared 1.85 million years ago, and disappeared 400 thousand years ago. A successful hunter, he invented many tools, got a home, and learned to use fire. The tools used by the erect man were larger than those of the early hominids (man and his immediate ancestors). When they were made, a new technology was used – the stone blank lining on both sides. They represent the next stage of culture – the Acheulean, named after the first finds in Saint-Acheul, a suburb of Amiens in France.
