Résumé / Abstract

Systematists should distinguish between cladistic analysis, i.e., a numerical procedure, and phylogenetic analysis, i.e., the reconstruction of hierarchic descent relationships. Modern cladistic analysis uses parsimony to construct hierarchic arrangements (trees) of terminal units (terminals) that have been scored for a series of attributes. The interpretation of cladistic relationships as representative of phylogenetic relationships requires two conditions, both of which were identified by Hennig (1966, Phylogenetic systematics, Univ. Illinois Press, Urbana). First, descent relationships among the terminals must be hierarchic; that is, all terminals must have been generated by the subdivision or replication of previously existing ancestors
