The evolution of homologous characteristics into new forms/phenotypes in the same clade. “Descent with modification” The evolution of analogous characteristics in distantly related clades 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
