If to speak about people as about a look, it is possible to notice that people nevertheless learned to cooperate. We make a sacrifice for the sake of others and we work together. And still we can "read out" emotions of other people and sometimes foresee their intentions. All this led to emergence of culture, writing and other to that similar important things which, whatever one may do, are peculiar only to the person.
Also people learned to suffer invasion of other people into personal space, especially in the cities. We live in such crowded conditions which did not dream other animal species (certainly, the speech about those who are not placed in so constrained conditions by will of the person).
That is it is possible to tell that at us tolerance level to each other and interest to similar very much grew. And it is already similar to what occurred in an experiment on domestication of foxes Dmitry Belyaev.
And at the same time – a paradox, huh? – being so peaceful creation, the person remains the most aggressive being on Earth.
Animals help to shed light on this paradox to us … again!
If to compare, for example, dogs to their wild ancestor, we can see changes, including in the structure of a skull – as, however, and at many other cultivated animals. For example, the skull decreases in sizes.
And what about people? It appears, the biggest size of a human skull – not at modern people. The people living 20 - 30 millennia ago had the biggest head.
In the course of domestication of animals also the shape of their skull changes. And it concerns the person too!
That is, in fact, one may say, that people passed the same evolutionary way, as animals in the course of domestication.
Then people "samoodomashnitsya"? What this process is connected with?
Scientists from the Dyuka university (USA) of Bob Cerri, Steve Churchill and Qin Xi Qan conducted a research, having compared people who were engaged in hunting and collecting, with people who already passed to agricultural works. Scientists assumed that transition to a settled way of life, processing of the earth and cultivation of food demanded from people to be more peaceful, interested in interaction with other people and capable to move. And it is connected with those changes of the building about which it was mentioned above.
Possibly, people underwent natural selection on tolerance to tribespeople, interest in communication with them and decrease in level of aggression too. Just as dogs and experimental foxes, and almost (but yet not absolutely) as
