The Vertebrates (Revised version)

Considers the classification of vertebrates, including cartilaginous fish, bony fish, amphibians, reptiles, birds, and mammals. Highlights physical characteristics, environmental adaptations, and reproductive behaviors that differentiate the groupings. Notes the transition from cold-blooded to warm-blooded animals and possible evolutionary links, including coelacanth, dipneust, and archeopteryx. Shows mammals particularly suited for land, air, and aquatic life, and conludes with man--a remarkable primate set apart by the refinement of the brain and hand., Considers the classification of vertebrates, including cartilaginous fish, bony fish, amphibians, reptiles, birds, and mammals.
