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