The principal form of the biological adaptation of man is behavior. A question arises in this connections — can the natural selection affect the formation of a definite type of behavior even if the behavior is primarily an ontogenetic adaptation? Man is the most domesticated from all the species, since during the period of anthroposociogenesis the natural selection concerned primarily the socially adapted behaviour. The human society possessed as its main advantage in the struggle for life a common exploitation of tools and hence it required from its members not only supression of aggressiveness in relations of their fellows, but also the ability to coordinate complex actions in providing food, protection from enemies and upbringing of slowly maturing offsprings. We can assume that some changes in the neuro-hormonal regulation which appear in the phenomenon of neoteny, were related in a definite manner to changes in the behaviour. During the formation period of the Homo sapiens species the dominant group of characters was represented by those securing of adaptation of individuals to the existence in the society, although many other things have changed too, these changes follow from correlation independences.
