Document Summary
A division of species that differs from other divisions by the frequency with which certain hereditary traits appear among its members - brues (1977) The majority of anthropologists agree that there are no biological races in humans. Race cannot meaningfully explain variation observed in human populations. Never an agreement on the number of human races. Biological variation is real; the order we impose on this variation by using the concept of race is not . Shape and size of the head and body. Shape and size of the underlying skeleton. Different traits often show very different distributions. Closer to the equator will have darker skin for protection and farther to the north and south will have less dark skin because less uv radiation won"t affect them so much. Genetic drift and gene flow that affect the evolutionary factors the whole genome. Natural selection affects only a subset of genes.
