Contemporary research in the field of evolutionary developmental biology, or 'evo-devo', has to date been predominantly devoted to interpreting basic features of animal architecture in molecular genetics terms. Considerably less time has been spent on the exploitation of the wealth of facts and concepts available from traditional disciplines, such as comparative morphology, even though these traditional approaches can continue to offer a fresh insight into evolutionary developmental questions. The Development of Animal Form aims to integrate traditional morphological and contemporary molecular genetic approaches and to deal with post-embryonic development as well. This approach leads to unconventional views on the basic features of animal organization, such as body axes, symmetry, segments, body regions, appendages and related concepts. This book will be of particular interest to graduate students and researchers in evolutionary and developmental biology, as well as to those in related areas of cell biology, genetics and zoology.The thorax can produce a second abdomen, and the abdomen can produce a second thorax. ... No structural or functional evidence of the original duplicity has been recorded in the young fish after hatching (Carter and Wourms 1993). ... Starfish with more than five rays are much less familiar than their five-ray counterpart, but are nothing of a rarity, having evolved independently in fourteen living families.
