Vertebrate Zoology is the study of animals with backbones. The evolution from Hemichordata and Protochordata to modern vertebrates will be discussed. Characteristics and evolutionary success of various vertebrate class such as Agnatha, Placoderma, Ostracoderm, Chondrichthyes, Osteichthyes, Amphibian, Reptilian, Aves and Mammal will be discussed with special references and comparison with vertebrate palaeontology and current status in vertebrate studies. The topic will be focused on several vertebrate issues such as anatomy, structure, adaptation, life cycles, diversity and conservation for each major class of vertebrate. In addition to the published facts about vertebrates, students will be introduced to important ideas in the areas of evolutionary biology, systematics, morphology, and ecology that form the basis of the conceptual understanding of a selected group of animals.
