cladistics




A system of classifying organisms on the basis of measurable similarities between their respective organs, parts, or biological structures. Organisms that share several characteristics are put into taxonomic groups known as clades. A cladogram is a diagram, resembling a sideways family tree, that shows how pairs or groups of clades diverged from common ancestors. Not all taxonomists agree about the validity of cladistics. See taxonomy.
