_Epigenetic Principles of Evolution, Second Edition,_ fully examines the causal basis of evolution from an epigenetic point-of-view. By revealing the epigenetic uses of the genetic toolkit, this work demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theoretical perspective with examples from varied fields of biology, emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. Users will find a broader view of the epigenetic mechanisms of evolution, moving beyond conventional changes in epigenetic structures, such as DNA methylation, histone modifications, and patterns of miRNA, sRNA, and mRNA expression. This second edition is thoroughly updated to reflect new evidence and developing theories in the field of evolutionary epigenetics. New and revised chapters speak to the epigenetic basis of heredity, epigenetic regulation of animal structure and homeostasis, neural manipulation of gene expression, central control of gametogenesis, epigenetic control of early development, the origin of epigenetic information, evolutionary changes in response to environmental stressors, epigenetics of sympatric evolution, and the epigenetics of the Cambrian explosion, among other topics. * Adopts an integrative approach to examine the causal basis of evolution from an epigenetic point-of-view * Features new and revised chapters which reflect novel experimental and observational evidence in the field of evolutionary epigenetics, as well as alternative theoretical approaches * Offers a broad view of epigenetic mechanisms of evolution, moving beyond conventional changes in epigenetic mechanisms, such as DNA methylation, histone modifications, and patterns of miRNA, sRNA and mRNA expression
