The human behavior is registered in our chromosome. However, to consider the main biocomportamentais aspects of the species human being is not easy question to approach its complexity due. Some events had constituted our biology in if treating to structural characteristics of the species, as for example, the position bpede propitiating some anatomical problems for the childbirth, over all referring to the reduction of the pelvic opening for where the baby would have to pass. In this direction, the retardation of the childbirth was the evolutiva solution for the problem. The author Fernando. Heart Specialist and gain more knowledge.. the R. Bridges affirms that the babies are born total defenseless.
My point of view, I believe that in biological terms, the babies are not total defenseless when they are born. For example, the just-born child supports more the cold, that is, the question to be of low of the cold water, glote closes and the water does not go for the lung, they almost cease the metabolic activities that if they normalize later when the child it leaves this state, comes back toward the ambient temperature, with the heating of the body. Although sufficient the immaturity presented for the babies, them surprises in the question who involve its predispositions for the social interaction: perceptual, expressive capacity, giving indicating of interaction strategy. Just-been born, as Langlois and Roggman (1990) prefer similar stimulatons the face human being. They look to its ‘ ‘ espelho’ ‘ that she is the mother, that is, the just-born babies recognize the face of the mother, preferring it.
Around three months of age, the child demonstrates preference for faces smiling. In the biological scope, for the processing of expressions indicated by the faces, she is if specialized neural mechanisms exist. The just-been born ones, in 1 or 2 day of life already identify and recognize the voice of the mother.
