Resumo de TRANSISTION FOR the HUMANITY

Understanding of the differences between the Man and the other animals:
for Science Biological;
for Anthropology and Psychology.
For Biological sciences exist a kinship being the animal men and calls inferiors; they see the evolution as a biological process more or less uninterrupted, and they had only faced the man as plus one of the many forms of life. Or either, it differs in degree (Distance and generation number that separates relatives until the common trunk).
For Anthropology and Psychology, even so does not deny the animal nature of the man, they tend to face it as being only, not only - in degree, as also in species (Joint of very similar individuals between itself and to the ancestral ones, and that if they intercross. The species is the basic biological unit. Some species they constitute a sort). It has intelligence and, also, conscience; necessities and also values; fears and moral sense; not only a past, but also a history. Only the man, in short, it has culture.

Meaning of the racial differentiation ("Modern", appeared in the period glacial).
The age glacial, that it produced fast and radical modifications in the climate, in the formations terrestrial and the vegetation, has very comes being considered as a period where development had ideal conditions for one faster efficient e evolutivo of the man. This period also was that one where the cultural way it passed suplemental it, each time more, the natural environment in the process selective, intensifying, in way without precedents, and making to advance process of evolution of the human being.
Probably it was the time where the characteristics had been forged almost all typically human beings; all the encefálico nervous system of the man, its social structure based in the prohibition of the incest and its capacity to create and to use symbols, etc.
physical differences of the races human beings constitute, are clearly, any thing of very recent, having had beginning, probably, it has only 50.000 years, more or less, or either, according to more conservatives estimates, less than 1/100 of period of duration of all the hominídea ancestry, that is, the line of formation of man. The races are, exactly this: modern. They represent adaptations, many recent and secondary, of the color of the skin, the face structure, etc. - without a doubt adaptations to the climatic differences, mainly - that they had been processed when homo sapiens if it exhausted for the world, for return of the end of the glacial period. Such adaptations are, therefore, all they, subsequent to the formative basic process of neural development e anatomical, occurrence since the beginning of the hominídea ancestry, until the appearance, of the fifty one hundred and fifty milênios behind, of homo sapiens.
