Cladistics, Cladistics

It can be distinguished from other taxonomic systems, such as phenetics, by its focus on evolutionary relationships; while other systems usually use morphological similarities to group similar species into genera, families and other higher level classification, cladistics tries to construct a tree representing the ancestry of organisms and species. It differs from heavy emphasis on objective, quantitative analysis.

Cladistics originated in the field of biological systematics, but has been successfully applied in other disciplines: for example, to determine the relationships between the surviving manuscripts of the Canterbury Tales.

This can be seen as a predecessor to some methods of today's cladistics (namely distance matrix methods like neighbor-joining), but made no attempt to resolve phylogeny, only similarities.
