Diversifying selection is natural selection that favors extreme phenotypes over intermediate phenotypes.It was in sculpture that human physical dimensions were visibly illustrated.Cultural evolution hinders application of natural selection to humans By Ken Weiss Charles Darwin avoided dealing with human origins in his “On the Origin of Species”(1859).Genes that contribute to the adaptive evolution of several relatively simple human traits like skin color or resistance to malaria have been identified.- Selection is the functional relationship between phenotypes and fitness.A heritable trait is one that's passed on from parents to children by way of genes.
