This is a field of study that allows biologists to reconstruct a pattern of evolutionary events resulting in the distribution and diversity of present-day life. Achieving this goal requires classifying organisms into groups in a meaningful and...

Cladistics, also known as phylogenetic systematics, is the study of the evolutionary history of relationships among organisms based on similarities derived from a common ancestor. The recency of a common ancestor is recognized by genealogical...

For the scientific journal, see Cladistics (journal). Cladistics is the hierarchical classification of species based on evolutionary ancestry. Cladistics is distinguished from other taxonomic classification systems because it focuses on evolution...

ABSTRACT-We compare cladistic, phonetic, stratophenetic, and typological methods of recognizing species within a single well-sampled, long-lived Ordovician bryozoan genus, Peronopora Nicholson, 1881. A consensus of 11 methods recognizes 14 species within Peronopora, each of which has both eladistic and phenetic support, and support by...
