Zoology, Fifth Edition

Principles-oriented introductory zoology text for non-majors or combined majors/non-majors (freshman-sophomore level). An introductory general zoology text that is manageable in size and adaptable to a variety of course formats.

Zoology is organized into three parts. Part One covers the common life processes, including cell and tissue structure and function, the genetic basis of evolution, and the evolutionary and ecological principles that unify all life. Part Two is the survey of animals, emphasizing evolutionary and ecological relationships, aspects of animal organization that unite major animal phyla, and animal adaptations. All of the chapters in Part Two have been carefully updated, including new examples and photographs. The coverage of animal classification and organization in Chapter 7 has been expanded from previous editions to include more background on cladistics and enhanced coverage of protostome/deuterostome relationships. As in previous editions, the remaining survey chapters (8–22) include cladograms to depict evolutionary relationships, full-color artwork and photographs, and lists of phylum characteristics. Part Three covers animal form and function using a comparative approach. This approach includes descriptions and fullcolor artwork that depict the evolutionary changes in the structure and function of selected organ systems. Part Three includes an appropriate balance between invertebrate and vertebrate descriptions.
