Zusammenfassung:The evolution of segmentation is one of the central questions in evolutionary developmental biology. Indeed, it is one of the best case studies for the role of changes in development in the evolution of body plans. Segmented body plans are believed to have appeared several times in animal evolution, and to have contributed significantly to the evolutionary success of the taxa in which they are present. Because of the centrality of the subject, and the continuing interest in understanding segmentation, this book offers an often overlooked focus on the cellular aspects of the process of segmentation, providing an invaluable reference for students of evolutionary developmental biology at all levels. Key Features Explores the role that segmentation has played in the diversity of animals Documents the diverse cellular mechanisms by which segmentation develops Reviews the independent evolutionary origins of segmentation Provides insight into the general patterns of serial homology at the cellular level Related Titles Lynne Bianchi.
