The idea of a gradual and continuous change of all species of plants and animals was expressed by many scientists long before Charles Darwin. Therefore, the notion of evolution has penetrated into science in the late XVIII century. However, it was Darwin who proposed an entirely new hypothesis regarding nature, summarizing some evolutionary ideas into one, the so-called theory of evolution, which received the widest dissemination in the world.
Regardless of the fact that neither the scientists nor the people seem to find any consensus on how a human has evolved, almost all of them agree that a certain effect has been made by the process of evolution. In simple words, evolution is a series of development that occurred because of genetics and changing environmental factors.
The diversity of views on anthropogenesis is, indeed, endless, yet there are confirmed by a number of archaeological and biological data facts that claim that it took a lengthy path of so-called mutations for ancestor of ours to turn into modern humans.
There are three main stages of human development identified by the scientists. First, the most ancient people, such as Pithecanthropus, Sinanthropus, and Heidelberg man (also known as Homo erectus). The second stage falls under the ancient times and is concerned with ancient people — the Neanderthals. Last, modern people, including Cro-Magnon and modern humans, more commonly known as Homo Sapiens.
With today’s technology, we are able to establish the age of any bones or remains with the radioactive analysis. It is because each bone has radioactive substances, that gradually disintegrate after the death of the animal. Knowing the rate of decay of these substances, one can calculate in what era exactly the animal lived.
As for today, the scientists have proven that the human society goes was formed 2 million years ago in East Africa. Gradually the people settled all over the globe and found their homes among the vast expanses of Asia, Europe, America, Australia and Oceania. Somewhere around 6500 BC, humans started creating first civilizations in the valleys of the largest and most fertile rivers of our planet: the Tigris and the Euphrates in the Middle East and the Nile in northeast Africa.
