Vertebrate evolution is studied through comparative anatomy and functional morphology of existing vertebrates as well as fossil records. Since the publication of the previous edition of Colbert's Evolution of the Vertebrates: A History of the Backboned Animals Through Time, there have been significant advances in the knowledge surrounding backboned animals. This latest edition of the classic text is completely revised to offer the most recent discoveries in this continually evolving field of science. Covering the various aspects of vertebrate life, from skeletal system to ecology, behavior, and physiology, the Fifth Edition includes new sections on conodonts, dinosaurs, primates, and the origin of birds, and discusses: Analysis of morphological and molecular data Early diversification of vertebrates The evolution of dinosaurs The origin of mammals Early ruling reptiles Basic adaptation of ungulates Colbert's Evolution of the Vertebrates, Fifth Edition carries on its legacy as an invaluable reference for professionals in evolutionary biology and paleontology, as well as an ideal textbook for students in those fields.
