'The authors … are well situated to consider and elaborate on cladistic philosophy and applications in biological and evolutionary studies. This volume … will provide a solid background in the general study of classification, the major considerations for determining taxon relationships, a bit of history, and solid discussion on the use and theory of cladistics with various examples and citations for reference.'
