If you take the labour tools of that period, arrange them in time, it can be clearly seen that a decrease in brain size and their improvement seems to be frozen. But what had been achieved was handed down from generation to generation for thousands of years. Public consciousness through the socialization remembered what ancestors made. The social motivators are able to maintain and transfer knowledge and experience from generation to generation. And we must agree with S. Saveliev: “The situation looks quite anecdotal. Very capable people with big brains create a complex and effective system of training and retention of knowledge for the entire population. Having taught the less capable relatives the lessons of survivals, they doom themselves to destruction. Humanity faces such situation now.” [11, page 292].
He continues: "In large but relatively closed populations, even with the obvious benefits, non-standard people are usually sacrificed in order to preserve the stability of relations. In this regard, the probability of survival and reproductive success especially in these individuals is always very low. But more socially adapted representatives of community have the opportunity to reproductive success that is much higher. There is no secret that social adaptation is often accompanied by significant intellectual limitations. These differences between individuals have become the hidden driving forces for the artificial selection". [11, page 294].
And at present time the relations between the domain experts and social motivators are the hidden force of the social and economic development. This force is hidden and powerful due to the misunderstanding of its sense, misunderstanding of its dependence from the definite system of determinants that have the property to accumulate and reveal its effect cumulatively.
Through the skulls of our ancestors, with the help of the comparison of their brain on different levels of evolution, through the comparison of the brain of monkey and human and through other methods the scientists revealed the parts of the brain that are responsible for socialization. These are the frontal areas of the brain. Along with the socialization these parts are responsible for the real-imaginative forecasting that was necessary for hunting.
