Starting from Darwin's evolution theory, this paper expounds: 1. Biolo gy's and culture's action on development, analyzed since historic-cult ural psychology,human ethology, and sociobiology. This work, focusing historic-cultural psychology, emphasizes the culture and the individua l's assimilation process of society's historic development. 2. Psychic activity in primates, analyzing the psychic as brain function, and as objective world's reflex. Experiments with nonhuman primates suggest more and more a different class of adaptation in animal with respect t o man, which is the cause of the lack of chimpanzee's cultural develop ment.
