Inter Races

The Inter-racial crossings had become frequent and the humanity is amalgamating in a species each more homogeneous time, but with great variations. Populations that if intercruzam widely present small genetic differences, but the isolated populations for long time develop considerable differences. In theory, races are populations of one same species that they differ how much to the frequency from genes, exactly that these differences are small. The division of the humanity in determined number of races is arbitrary; the important one is to recognize that the species human being, as excessively, is divided in some bigger racial groups that, in turn, if subdivide less in races distinct, and the subdivision continues until if arriving the populations that almost do not present differences. Nir Barzilai, M.D.: the source for more info. The subspecies represent the last evolutivo stadium in the differentiation of the races, before the establishment of the mechanisms of reproductive isolation.

They are, therefore, distinguveis for presenting certain well different characteristics in frequency. If they do not cross, for being separate, but they are capable to produce hybrid fertile, if placed together. For this criterion, that is the accepted one for modern biology, the natives of Africa and the Amazonian forest, for example, they are races that had reached the level of subspecies fully. The same it can be said of the Italians and the eskimos etc., but it does not have human groups that they have been differentiated in distinct species, therefore species are biological groups that are not intercruzam habitually in the nature, exactly when the individuals inhabit the same territory. Criacionismo + Evolucionismo Placing itself criacionismo and evolucionismos, pair pair, would be possible to harmonize both the theories in an only one that it consolidated what it is known without invalidating none of the two? I think that yes, let us see: If God created the nature is evident that we perceive its action as if perceives the proper nature, moreover, for God the time is not problem, then, for It, as, one hour, one day, a century, one millenium, an age, does not make any direction, exactly because when it relates in them we use adjectives such as: onipotente, onisciente, onipresente, perpetual, I AM WHAT I AM, since always and forever, spirit, light, infinite love, perfect, indescritvel, unimaginable sanctity, among others, if we cannot see it, but we can see its action, its action in them seems natural, that is, the proper nature.
