cladistn.

1965 Systematic Zool. 14 78/2 The cladists..are forced to reconstruct the branching points by relying entirely on the differences found among existing taxa and on various deductive principles.

1968 Nature 9 Mar. 548/1 What the cladists forget is that the term ‘relationship’ has two different biological meanings, genetic relationship and genealogical relationship.

1969 E. Mayr Princ. Systematic Zool. x. 230 The cladists..base categorical rank on the geological time at which the ancestor of a given taxon branched off from the parental stem (or from a sister branch).

1979 Nature 18 Jan. 176/1 Cladists..infer that lungfish and cows shared a more recent common ancestor..from the fact that lungfish and cows share derived characters..not found in salmon.

1982 London Rev. Bks. 4 xxiv. 13/1 The taxonomists classify themselves as cladists or evolutionary systematists.

1966 Systematic Zool. 15 91/2 I believe Mayr is wrong in regarding cladism almost as a crime against science.

1968 Nature 9 Nov. 547/2 The basic fallacy of cladism is to overlook the fact that ‘relationship’ in the evolutionary sense is determined not merely by branching but also by the subsequent divergence.

1982 Zool. Jrnl. Linn. Soc. 74 323 Cladism..passed, or is passing, through a phase of arrogant and repellent dogmatism which likewise unleashed a storm of often ill-informed criticism.
