   The term "cladistic" was created by Rensch (1960, Evolution above the species level)
and distributed after works Cain, Harrison, 1960 , Phyletic weighting
Proc. Zool. Soc. London, v. 135, pt.1 and Mayr, 1965, Classification and phylogeny,
Amer.  Zool, v. 5, n. 1. (Based on review of Yu.A.Pesenko,1989, Methodological analysis of
systematics 1. Classification of the problem, The main taxonomic schools,
Proc. Zool. Inst., Leningrad, v. 206., in Russian).
   Hennigian "phylogenetic systematic" probably seemed unclear and wide
for above mentioned authors, who changed this term to more definite "cladistic".
For me the "phylogenetic systematic" exactly reflect essence of Hennigian method,
because Hennig convinced most taxonomists that taxonomy and phylogeny is same things.
