The following article tries to establish nexuses and relations that occur between the evolution of the prehuman hominidous one as the base of the properly human psychism and to show how the changes that hereditarily are transmitted, have to physically take place in the germinal plasma, because from the morphologic structures the own psychism of the new species arises. One is a process of potentialities not merely biological but Metaphysical, in which the biochemical structures will demand for their own viability, the use of intelligence. The psychism is not an extrinsic creation, is on the contrary an intrinsic exigencial fulfillment, determined from the structures, is not a mere fulfillment, but absolute innovation. There is a psychosomatic blossoming, one intellect psique, in which the creative action not only does not interrupt the course of the evolution but it is the mechanism that finishes carrying out it. Evolution is to give of himself in potentiation, is not to change but to integrate the mutation in giving of himself like intrinsic, formal and structural moment of the matter. Thus, the life is an innovation that the material sustantivity gives of himself by mere systematization, for that reason tenth that all the psychic one is somatic and all the somatic one is psychic. The experimental embryology and the genetic engineering let us know that in the first stages of the development - zygote and morule- are not established the specificity of the germ, more than it can say then is that the zygote of the human species is a man in conditional power, to which it only can attribute him to human condition with the gastrulation and the formation of the blastodermic leaves and more explicit way with the appearance of the neural crest. Appearing of human psique occurs when in the embryo appears a clear outline of the nervous system, this structure is the one that gives rise to the simbolization, to the left and right cerebral modes, allows to know the world, to make the life and allows all the human specific activities.
