Epigenetic Mechanisms of the Cambrian Explosion provides readers with a basic biological knowledge and epigenetic explanation of the biological puzzle of the Cambrian explosion, the unprecedented rapid diversification of animals that began 542 million years ago. During an evolutionarily instant of ~10 million years, which represents only 0.3% of the time of existence of life on Earth, or less than 2% of the time of existence of metazoans, all of the 30 extant body plans, major animal groups (phyla) and several extinct groups appeared. The work helps address this phenomena and tries to answer remaining questions for evolutionary biology, epigenetics, and scientific researchers. The book recognizes and presents objective representations of alternative theories for epigenetic evolution in this period, with the author drawing on his epigenetic theory of evolution to explain the causal basis of the Cambrian explosion. Both empirical evidence and theoretical arguments are presented in support of this thought-provoking epigenetic theory. Explains the Cambrian explosion from an entirely epigenetic view Takes a causal rather than descriptive approach to the phenomenon Allows for a broad readership, including those with only a basic biological knowledge, while maintaining scientific rigor

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

Cabej (biology, U. of Tirana, Albania) explains the epigenetic principles of evolution (as opposed to the theory of evolution as determined by changes in genes) and reconstructs the developmental mechanisms of evolutionary changes in metazoans, based on empirical evidence. He focuses on the mechanisms of the generation of the evolutionary innovations from the influence of environment on heredity rather than the role of natural selection. He discusses control systems and determination of phenotypic traits in metazoans, neural manipulation of gene expression, epigenetic control of reproduction and early development, neural control of postphylotypic development, and the epigenetic system of inheritance. He follows with description of neural-developmental premises of evolutionary adaptation, including evolution and stress responses and behavioral adaptation to changes in environment, ontogeny, and intragenerational developmental plasticity; epigenetics of circumevolutionary phenomena and the mechanism of evolutionary change, including transgenerational developmental plasticity and the evolution of metazoans and their control system; and the origins of evolutionary novelty, evolution by loss or by reverting to ancestral characters, neural crest-determined evolutionary novelties, evolutionary convergences, species and allopatric speciation, and sympatric speciation. He presents the available evidence for his theory, rather than illustrating an established theory, and includes a comparative presentation of the neo-Darwinian view to his epigenetic explanation.

Building the Most Complex Structure on Earth provides readers with a basic biological education an easy and understandable introduction into a new epigenetic theory of development and evolution. This is a novel theory that describes the epigenetic mechanisms of the development and evolution of animals and explains the colossal evolution and diversification of animals from a new post-genetic perspective. Modern biology has demonstrated the existence of a common genetic toolkit in the animal kingdom, but neither the number of genes nor the evolution of new genes is responsible for the development and evolution of animals. The failure to understand how the same genetic toolkit is used to produce millions of widely different animal forms remains a perplexing conundrum in modern biology. The novel theory shows that the development and evolution of the animal kingdom are functions of epigenetic mechanisms, which are the competent users of the genetic toolkit. Provides a comprehensive view of the epigenetic aspects of reproduction, development, and evolution. Highly rigorous, but simple enough for readers with only a basic knowledge of biology.

A riveting explanation of epigenetics, offering startling insights into our inheritable traits. In the 1700s, Jean-Baptiste Lamarck first described epigenetics to explain the inheritance of acquired characteristics; however, his theory was supplanted in the 1800s by Darwin's theory of evolution by natural selection through heritable genetic mutations. But natural selection could not adequately explain how rapidly species re-diversified and repopulated after mass extinctions. Now advances in the study of DNA and RNA have resurrected epigenetics, which can create radical physical and physiological changes in subsequent generations by the simple addition of a single small molecule, thus passing along a propensity for molecules to attach in the same places in the next generation. Epigenetics is a complex process, but paleontologist and astrobiologist Peter Ward breaks it down for general readers, using the epigenetic paradigm to reexamine how the history of our species-from deep time to the outbreak of the Black Plague and into the present-has left its mark on our physiology, behavior, and intelligence. Most alarming are chapters about epigenetic changes we are undergoing now triggered by toxins, environmental pollutants, famine, poor nutrition, and overexposure to violence. Lamarck's Revenge is an eye-opening and provocative exploration of how traits are inherited, and how outside influences drive what we pass along to our progeny.

Nongenetic Information and Evolution investigates the origin and nature of nongenetic information and its role in the mechanisms of evolutionary change. The book opens with an introduction to the theoretical background and forms of nongenetic information, alongside its relationship with genetic information. It then explores nongenetic information across the biological kingdoms, including animals, non-neural organisms, plants, and unicellulars. It also covers epigenetics as a form of nongenetic information, exploring DNA methylation, histone modifications, chromatin remodeling and miRNA expression in this context. The book closes with a discussion of nongenetic information in evolution, considering evidence demonstrating its inheritance and hereditary impact. This book provides a detailed overview of the origin and evolutionary impact of nongenetic inheritance, delivering a basis for further understanding the occurrence of hereditary phenomena and transgenerational phenotypic changes that do not involve genes. This is a useful reference for researchers in the field of epigenetics, evolutionary biology, developmental biology, and cellular and molecular biology.
