5. Divergent evolution describes evolution toward different traits in closely related species. Divergent evolution can lead to speciation.kit foxancestorred fox
6. EVOLUTIONARY CLASSIFICATIONBiologists group organisms into categories that represent lines of evolutionary descent, or phylogeny, not just physical similarities.What is Phylogeny: The study of evolutionary relationships among organisms.
7. CladogramsABCDEFSpeciation: formation of two new species from oneClade or lineageTIME
8. Classification using Cladograms Cladograms are diagrams that use derived characteristics to illustrate evolutionary relationships. What is a Clade: A group of organisms, such as a species, whose members share homologous features derived from a common ancestor.
