Thus, there is the opinion of paleontologists that the relations between the domain experts and social motivators for thousands of years defined the main tendencies of development of our intellect, brain, our evolution. Those ancestors of people who walked not the way of the submission to circumstances of socialization, but developed their individual abilities just were extinct. The Neanderthals gave their place to Cro-Magnons.
There are facts such as the increasing of the frontal areas of the brain and decrease of the brain itself in the process of human evolution. But the mass of the female brain is always smaller than the male. These differences are not constant and depend on ethnic characteristics (see: Takahashi, Suzuki, 1961.). In addition, a large part of the evolution of the human brain was held in the period of matriarchy and it does not deny the thoughts expressed by S. Saveliev, but simply clarifies them.
Yes, women played the decisive role in the formation of a tribe and in the socialization process. They caught the slightest reaction of the child since its birth, thereby keeping him alive. Their biological function – the birth and procreation – gave them the undeniable advantages in understanding, in feeling of a human being and in the management of them not through force but through empathy, through the feeling of another person, through empathy with him or her. Woman gets used to the child, and she has the more developed ability to do this than a man. Therefore it is possible to suppose with a high degree of certainty that social motivators of that time were with the characteristics of empathic individuals.
Reducing of the weight of the brain took place also for the reason that human changed in two directions – in the direction of increasing of the frontal lobe (this is a purely male part of the brain, it is largely responsible for the success of the hunt), and towards the development of empathy, feelings of other people, for example in the direction of copying the features of the female brain. In their evolution our ancestors took the best both from men and from women. Of course, in different nations the ratio of male and female in the brain was formed in different ways. Each ethnic group has its own weight ratio of male and female brain. But in all ethnic groups the dependence can be traced: the front part of the brain is the male, and the rear is the female.
