As suggested by Darwin’s theory, discussed in the introduction to this part, adaptation will occur over time, with the result that new species will evolve and existing species will adapt and change, in order to obtain optimum advantage from changing environments; that is to say, to have the greatest chance for genes to survive into succeeding generations. This adaptation of a species over time, by natural selection, is called phylogenetic adaptation.
