cladistics

(klə-dĭs′tĭks)
n. (used with a sing. verb)
A system of classification based on the presumed phylogenetic relationships and evolutionary history of groups of organisms.

cla·dis′tic, cla·dis′ti·cal adj.
cla·dis′ti·cal·ly adv.

cladistics

an approach to CLASSIFICATION by which organisms are ordered and ranked entirely on a basis which reflects recent origin from a common ancestor, i.e. like a family tree. The system is concerned simply with the branching of the tree and not with the degree of difference. The latter is the concern of evolutionary taxonomists who oppose the cladistic approach.

Cladistics works most effectively when either absence-presence and/or other qualitative characters are used (e.g.

I was also surprised that phenetics and cladistics were explained but the "evolutionary" view of systematics was not even mentioned.
Modern versions of the comparative method, inspired by phylogenetic systematics (cladistics), provide convenient tools for testing these assumptions.
Moreover, as nonexperts in the subject they summarize, they give the impression of being perhaps overly impressed with such methodological innovations as cladistics and its imputed power to determine what pre-World War II paleoanthropologists called the "Missing link," which Maryanski and Turner denote as the last common ancestor among humans and other great apes.
