Difference between cladistics and phylogeny. Cladistics is now accepted as the best method available for phylogenetic analysis, for it provides an explicit and testable hypothesis of organismal relationships. If other theoretical ancestors of other groups have the same physical characteristics, the two groups, or clades, can be said to be related somehow. Groups of species are called clades.
