The field of evolutionary biology arose from the desire to understand the origin and diversity of biological forms. In recent years, however, evolutionary genetics, with its focus on the modification and inheritance of presumed genetic programs, has all but overwhelmed other aspects of evolutionary biology. This has led to the neglect of the study of the generative origins of biological form.
Drawing on work from developmental biology, paleontology, developmental and population genetics, cancer research, physics, and theoretical biology, Origination of Organismal Form explores the multiple factors responsible for the origination of biological form. It examines the essential problems of morphological evolution – why, for example, the basic body plans of nearly all metazoans arose within a relatively short time span, why similar morphological design motifs appear in phylogenetically independent lineages, and how new structural elements are added to the body plan of a given phylogenetic lineage. It also examines discordances between genetic and phenotypic change, the physical determinants of morphogenesis, and the role of epigenetic processes in evolution. Origination of Organismal Form discusses these and other topics within the framework of evolutionary developmental biology, a new research agenda that concerns the interaction of development and evolution in the generation of biological form. By placing epigenetic processes, rather than gene sequence and gene expression changes, at the center of morphological origination, Origination of Organismal Form points the way to a more comprehensive theory of evolution.

"This volume challenges the primacy of both neo-Darwinian evolutionary theory and developmental genetics as complete explanations for the phenomena of evolutionary developmental biology. The contributors take a refreshing variety of approaches to classic problems such as homology, developmental constraints, modules, and roles for environmental factors in development. This original and well-argued contribution is essential reading for anyone interested in the evolution-development synthesis."
– Rudolf A. Raff, Distinguished Professor of Biology, Indiana University
