Description
Book SynopsisNeither cellular/molecular nor ecosystem processes can be fully understood without a detailed understanding of the biology of the whole organism. Despite this, much of modern biology teaching tends to be focused on the cellular and molecular level, with the organism often neglected. This is particularly noticeable in many undergraduate biology programs, where introductory courses in animal biology are either given with limited evolutionary context or else use an outdated view of animal phylogeny. This accessible textbook provides a general conceptual framework for understanding the organismic level. It provides a broad overview of the diversity of animal life while focusing on general organizational principles with a few, carefully chosen examples rather than providing exhaustive specific details. The book adopts two parallel tracks, with most chapters focusing on one or the other. The first follows the general principles of organismic biology and animal organization, starting with the
