Animal Diversity. Fourth Edition.

A top choice among students and instructors alike, Animal Diversity continues to earn the appreciation of both science majors and non-majors alike. The book uses the theme of evolution to develop a broad-scale view of animal diversity—students focus not only the organisms themselves, but also the processes that produce evolutionary diversity. The book is unique in its comprehensive survey of zoological diversity and its emphasis on evolutionary, systematic and ecological principles, all in one package.
