This volume contains reviews from the world’s leading researchers who are using echinoderms to address these questions. Chapters focus on gene regulatory networks that drive the differentiation and morphogenesis of major embryonic tissues such as the skeleton, muscle, nervous system, immune system, pigment cells, and germ line, and on evolutionary insights from comparative studies of these networks across echinoderms and other taxa. Other chapters comprehensively review the architecture and evolution of the cell signaling pathways that establish the early embryonic axes and on recent evolutionary changes in gene networks that have led to dramatic changes in the life history modes of echinoderms. This volume provides a comprehensive, current picture of exciting research at the interface between developmental genomics and evolution from one of the research communities leading this work.
