Unformatted text preview: Using cladistic methods, one can test biogeographic hypotheses by asking whether area cladograms for other, unrelated taxa are congruent . If different taxa all have similar area cladograms (i.e., are "congruent"), then the sequence of vicariance events is supported. If one taxon is represented in a region where none of the other taxa are found, then one might be forced to invoke dispersal to account for the disjunct distribution. The strength of this approach is that hypotheses are testable and one need not resort to ad hoc explanations that should be taken on faith.
