While it is still quite common to hear the views of the divine origin of man, or even cosmic, but people are educated and savvy can hardly doubt the truth. The emergence of Homo sapiens occurred during the biological evolution of anthropoid obezyan. By the middle of the XX century in the scientific community firmly established opinion about the African origin of human heart, and in 1974 the whole world shook a sensational discovery. Where African Rift divides into two "horns" in Ethiopia, in Afar region, was found a complete skeleton of Australopithecus afarensis, one of our most ancient ancestors, the age of about 3.8 million years. While all were passionate group of the Beatles, and the skeleton (it belonged to a female) was named Lucy, the eponymous song. This finding is summed up decades of hard and, sometimes, dramatic work on the study and systematization of data on the anatomy and way of life of early hominids and the first representatives of the genus Homo. Not touching the essence of much debate about human origins, we give the main results, which is now generally agreed academic science, based on extensive data research in paleoanthropology, Comparative genetics and evolutionary psychology.
1. We know exactly who was the direct ancestor of man kind (Homo). They were the gracile australopithecines, creatures with a small brain volume, but very active, with good social organization and had a real family. Homo genus Australopithecus or separated from other similar hominids about 2 million years ago in Africa. There are several types of people, most of whom had died. These include, inter alia, include erectus and Neanderthals.
The earliest representatives of Homo sapiens were the result of the evolution of 400-250 thousand years ago. 2. We know exactly the place of human origins. This is Africa, and that its area, which adjoins the Great Rift valley, crossing the continent from south to north. There are no other places of human origin have been identified. According to this ruling today in a science hypothesis, our species emerged in Africa and spread from there around the world, replacing existing populations in other regions of Homo erectus and Homo neanderthalensis. 3. We are certain that our early ancestors began walking on two legs at least 2 million years before they began to use specially made tools. It is interesting that Darwin knew nothing about the future of numerous anthropological finds, however, wrote in his book "The Descent of Man," that our ancestors probably lived in Africa. But why in Africa? This question is only beginning to be discussed in academic circles and is of great interest. Ask him to our guide and the tourists who buy the tour in Tanzania, "In the wake of the African Adam." Answer this and many other the evolution of life can be also bought in any book of scientific and popular novel DA Chernyakhovsky "Resources and Development: from bacteria to the market", or received it for free at our office.
