Publisher's Synopsis
This text presents a complete phylogenetic analysis of all animal phyla. Using modern cladistic techniques, each phylum is analyzed to ascertain that the units in the analysis belong to the same ancestral group, then gradually extended from the identification of sister phyla to the construction of a complete phylogenetic tree of extant metazoa. The systematic cladistic analysis of phylogenetic relationships has been integrated into a text which also describes the main features of the various groups.
