What is cladistics?</h3>
Cladistics is a method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.
A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.
