The evolution of homologous characteristics into new forms/phenotypes in the same clade. “Descent with modification” evolution at a relatively rapid rate tending to result in speedy differentiation and fixation of new types The evolution of analogous characteristics in distantly related clades Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species a branching diagram that shows how similar a group of things are to each other
