About the Authors
  • While neo-Darwinism has considerable explanatory power, it is widely recognized as lacking a component dealing with individual development, or ontogeny. This lack is particularly conspicuous when attempting to explain the evolutionary origin of the thirty-five or so animal body plans, and of the developmental trajectories that generate them. This significant work examines both the origin of body plans in particular and the evolution of animal development in general. Wallace Arthur ranges widely in his treatment, covering topics as diverse as comparative developmental genetics, selection theory, and Vendian/Cambrian fossils. He places particular emphasis on gene duplication, changes in spatio-temporal gene-expression patterns, internal selection, coevolution of interacting genes, and coadaptation. The book will be of particular interest to students and researchers in evolutionary biology, genetics, paleontology, and developmental biology.

    • There is currently no other book devoted to exploring possible evolutionary mechanisms underlying the origin of animal body plans
    • The book covers all biological levels of organization - from molecules and cells through organisms and populations to lineages and clades
    • The book takes a novel view of how natural selection modifies the genetic architecture of development: there is a particular emphasis on the concept of internal selection

    Reviews & endorsements

    "...excellent new book on evolution and development. He steers a pragmatic middle course between two complementary approaches to 'evo-devo'." Heredity

    "Arthur's book is an outstanding contribution to unifying developmental and evolutionary biology. The integration of popular genetics and ecology is particularly strong, and begins to fill a big gap in literature. Arthur does not shy away from making predictions, and rarely misses an opportunity to point out fruitful areas for future work. His writing is clear, concise, and insightful, making the book a delight to read. This book is required reading for anyone interested in the evolution of development." Gregory Wray, State University of New York, Stony Brook

    "The Origin of Animal Body Plans is an attractive, well-articulated and highly readable argument for expanding our current awareness of evolutionary processes. It helps to usher in a fully-fledged discipline of Evolutionary Developmental Biology which, among other things, emphasizes the importance of 'internal selection.'" Alessandro Minelli, University of Padua

    " takes a brave soul to tackle the subject. Authors venturing into this area must have a sound command of the breadth of several disciplines, combined with the depth that a historical perspective offers. They must be able to use language flawlessly...Wallace Arthur, though, scoops the pool...He sets out what he is going to say, says it with precision, and moves on. Concepts are summarized in handy tables and diagrams. No metaphysics, no sliding panels, Arthur just tells it like it is. For those who have found this subject daunting, this is the book for you." Biological Journal of the Linnean Society

    "Neo-Darwinism, to Arthur, is not 'wrong' but it is incomplete and 'horribly lopsided'. This book helps to remedy that situation." Reports
