Animal Phylogeny

Cladistics is a method of biological classification where organisms are classified based on their ancestors and their relationship with them. It is defined as the concepts and methods for determining the branching patterns of evolution and evolutionary history. Some scientists, however, have preferred the term phylogenetic systematics or phylogenetic taxonomy to emphasize the reliance on a phylogeny for classification. It is the most common and accepted method for classifying organisms.

Mammals have a particularly good sense of earing thanks to their inner ear which includes three tiny bones. Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are 1. an analogy 2. an exaptation 3. a living fossil 4. a transitional trait 5. a vestigial structure
