Question

what do you mean by cladistic taxonomy

Answer 1

a system of biological taxonomy that defines taxa uniquely by shared characteristics not found in ancestral groups and uses inferred evolutionary relationships to arrange taxa in a branching hierarchy such that all members of a given taxon have the same ancestors

Answer 2

A system of classification based on the presumed phylogenetic relationships and evolutionary history of groups of organisms, rather than purely on shared features. Many taxonomists prefer cladistics to the traditional hierarchies of Linnean classification systems.
