Beyond Heterochrony: The Evolution of Development
In looking beyond heterochrony, this book attends to a variety of explanations for evolutionary development. The chapters present theoretical and practical approaches with real data, using examples from both extant and extinct forms of animal and plant life to present refreshing and at times divergent perspectives on the subject.
Each chapter offers a substantive and original contribution to the literature, with case studies that explore the developmental basis of morphological evolution in a unique way. They address a number of issues and provide real data on which their conclusions rest, as well as the phylogenetic context of evolutionary interpretations.
The book includes thorough analysis of the ontogeny and phylogeny of shape-for decades the very heart of studies of heterochrony-and also presents novel approaches with new hypotheses. The hypotheses considered are as diverse as their analytical methodologies: each goes beyond heterochrony in a different way and in so doing, steers the discussion of the evolution of development in fascinating new directions.

"...biologists here consider that for too long [heterochrony] has been thought of as the single significant mechanism..." (SciTech Book News, Vol. 26, No. 2, June 2002)
"...a valuable contribution because of its wide compass and unfamiliar examples..." (British Society for Developmental Biology)
"...provides a valuable set of case studies that attempt to approach the concept of heterochrony rigorously..." (Heredity, 2003)
"The book certainly lives up to its title: it not only provides new data and analyses for classical and novel examples of heterochrony, but also suggests alternative interpretations or ways to describe evolutionary changes. The strongest point of the book is the serious attempt made by most of the authors to incorporate an explicit phylogenetic analysis." David H. A. Fitch, New York University
"Patterns of covariation permeate the study of evolution and development. This book provides a badly needed fresh look at these patterns, and does so in a reasonable and balanced way. It critiques the excessive simplicities of past approaches (such as that all developmental evolution is heterochrony) and provides constructive suggestions for improving them." Michael L. McKinney, Director, Environmental Studies Program and Professor of Geological Sciences and Ecology/Evolutionary Biology, University of Tennessee
