This diagram of an animal phylogenetic tree depicts the formal study of organisms and their evolutionary history about one. Phylogenetic trees are most commonly used to describe the relationships between species. They clarify whether certain traits are homologous or homoplasy found in the common ancestor as a result of divergent evolution sometimes referred to as analogous: a character not found in a common ancestor but whose function developed independently in two or more organisms through convergent evolution. As shown in this phylogenetic tree of animals diagram, evolutionary trees are diagrams that illustrate various biological species and their evolutionary relationships.
