This second edition of Comparative Anatomy of Vertebrates has been thoroughly revised. It is based around two fundamental themes. Part A, comprising the first eight chapters, is devoted to the discussion of chordates' evolution and classification. A detailed taxonomic synopsis for each class is included in the chapter dealing with that class. In addition a combination of phylogenetic trees (cladograms) and narrative discussions to unveil facts about animal evolution are included. Cladograms are used where appropriate. The book also discusses molecular-based hypotheses that have received widespread attention. Part B deals with comparative anatomy and provides an introduction to the structure-function concept at the level of organs and the organ system, which is fundamental to the understanding of synthesis of comparative anatomy. Key features: Treats the subject in a sequential manner Brief and lucid discussion of the subject matter Outline diagrams, taken from authentic sources, that can be easily reproduced
