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. A method of taxonomic
classification that groups organisms according to their lines of
evolutionary descent. All descendants of a given organism are
called a clade.
