|cladistics (klə-dĭs'tĭks) Pronunciation Key
A system of classification based on the phylogenetic relationships and evolutionary history of groups of organisms, rather than purely on shared features. Many modern taxonomists prefer cladistics to the traditional hierarchies of Linnean classification systems. Compare Linnean.
