The term "clade" was introduced in 1958 by Julian Huxley, "cladistic" by Cain and Harrison in 1960, and "cladist" (for an adherent of Hennig's school) by Mayr in 1965. Hennig referred to his own approach as "phylogenetic systematics". From the time of his original formulation until the end of the 1980s cladistics remained a minority approach to classification.
