Document Summary

Artificial selection: domestic animals and plants y to increase the frequency of desirable traits in their stocks, plant and animal breeders employ artificial selection (example of darwin and his pigeon s on page 74). Evolution by natural selection y darwin realized that a process like artificial selection occurs in nature y his theory of evolution by natural selection suggests that descent with modification is the logical outcome of four postulates: Individuals within populations are variable y y the variations among individuals are, at least in part, passed from parents to y offspring. In every generation, some individuals are most successful at surviving and reproducing than others y the survival and reproduction of individuals are not random; instead they are tied to the variation among individuals. The individuals with the most favourable variations, those who are better at surviving and reproducing, are naturally selected.
