This difference of one year in the development becomes the fragile human just-been born one, compared with neonatos of other species, exactly the too much primates. Salient also that, in virtue of the fragility to the rising, the mammals need cares and protection against predators for a longer period. In the case of the species human being, such fragility still more demands drawn out parental cares, and in such a way the birth of the attachment how much the development of the familiar institution has its origins in this artifice of the nature. By a survival question, greater parental investment was demanded e, in contrast to many other species, the basic presence of the reproductive male also. As this did not have very to be easy in a hostile environment as they were the African savannahs, then, one more time, the processes of natural election come back to act. To guarantee the cares of the mother, and its consequent survival, the babies start to present more persistently, during the course of its infancy until more or less the beginning of the adult life, characteristic forms of the beginning of its development. That is known for neotenia.

This was one of the forms that the nature found to keep the mothers next to its younglings for bigger periods, guaranteeing its survival for an innate attraction for these characteristics. Considering that in the primates the reproduction if characterizes for births of few younglings and great parental and/or group investment in each youngling, the success of our species alone was possible for the evolution of maternal and/or paternal mannering standards compatible with the increase of the demand of cares of the offspring. To say that a behavior standard is product of natural election, is the same that to say that this standard was selected by having presented adaptativas consequences. One admits, for example, that selective pressure has occurred on the human standards of affective entailing.
