Paperback. Condition: New. Print on Demand. This book presents a concise history of the theories that have shaped our understanding of animal classification, from the early ideas of protozoan to the complex theories of the present day. The author focuses on three key stages in the development of animal complexity, the diploblastic, triploblastic, and finally the evolution of the mesoderm and coelom. Delving into debates about the origins of the digestive system, and the relationship between the mouth and the anus, and considering evidence for and against invagination and delamination theories of development, the author builds an accessible historical record of animal classification theory.
