The book examines the role of the development of social relationships in the formation of the human brain. The reasons for the autonomization of the evolution of the nervous system and reproductive processes are described. The main stages of change in socio-economic formations are shown as a consequence of changes in the goals of artificial brain selection. The hidden mechanisms of social evolution, prospects for human development and degradation are discussed. It is proposed to replace the ongoing biological evolution of hominids with conscious instrumental selection using controlled cerebral sorting. The publication is intended for a wide range of readers who have discovered a brain and are concerned about its fate.
