Revisiting the 'Origin of Species' focuses on Darwin as theorizing on the origin of variations; showing that Darwin himself was never a pan-selectionist (in contrast to some of his followers) but was concerned with "other means of modification" (which makes him an evolutionary pluralist).

Contemporary interest in Darwin rises from a general ideal of what Darwin’s books ought to contain: a theory of transformation of species by natural selection. However, a reader opening Darwin’s masterpiece, On the Origin of Species, today may be struck by the fact that this "selectionist" view does not deliver the key to many aspects of the book. Without contesting the importance of natural selection to Darwinism, much less supposing that a fully-formed "Darwinism" stepped out of Darwin’s head in 1859, this innovative volume aims to return to the text of the Origin itself. Revisiting the 'Origin of Species' focuses on Darwin as theorising on the origin of variations; showing that Darwin himself was never a pan-selectionist (in contrast to some of his followers) but was concerned with "other means of modification" (which makes him an evolutionary pluralist). Furthermore, in contrast to common textbook presentations of "Darwinism", Hoquet stresses the fact that On the Origin of Species can lend itself to several contradictory interpretations. Thus, this volume identifies where rival interpretations have taken root; to unearth the ambiguities readers of Darwin have latched onto as they have produced a myriad of Darwinian legacies, each more or less faithful enough to the originator’s thought. Emphasising the historical features, complexities and intricacies of Darwin’s argument, Revisiting the 'Origin of Species' can be used by any lay readers opening Darwin’s On the Origin of Species. This volume will also appeal to students and researchers interested in areas such as Evolution, Natural Selection, Scientific Translations and Origins of Life.

Major inconsistencies in Darwin's theory of the origin of species by natural selection remained unresolved for over a century until the results of recent research in various genome projects led to the theory's reinterpretation. Reviewing this new information, Donald Forsdyke, a laboratory scientist involved in genome research, wondered whether similar discoveries could have been made a century earlier, by one of Darwin's contemporaries. The Origin of Species Revisited describes his investigation into the history of evolutionary biology and its startling conclusion. The trail led first to Joseph Hooker and Thomas Huxley, who had been both the theory's strongest supporters and its most penetrating critics, and eventually to the Victorian George Romanes and Darwin's young research associate William Bateson. Although these men were well-known, their resolution of the origin of species paradox has either been ignored (Romanes), or ignored and reviled (Bateson). Four years after Darwin's death, Romanes published a theory of the origin of species by means of "physiological selection" that resolved the inconsistencies in Darwin's theory and introduced the idea of a "peculiarity" of the reproductive system that allowed selective fertility between "physiological complements." Forsdyke argues that the chemical basis of the origin of species by physiological selection is actually the species-dependent component of the base composition of DNA, showing that Romanes thus anticipated modern biochemistry. Using this new perspective Forsdyke considers some of the outstanding problems in biology and medicine, including the question of how "self" is distinguished from "not-self" by members of different species. Finally he examines the political and ideological forces that led to Romanes' contribution to evolutionary biology remaining unappreciated until now.

Evolution: The Basics is an engaging introduction to the history, development and science of the theory of evolution. Beginning pre-Darwin and concluding with the latest research and controversies, readers are introduced to the origins of the idea of evolution, the ways in which it has developed and been adapted over time and the science underpinning it all. Topics addressed include: • early theories of evolution • the impact of Darwin’s On the Origin of Species • the discovery of genetics and Mendel’s experiments • molecular evolution and the discovery of DNA • the expansion of life and the persistence of disease • revisiting evolutionary ethics and the development of empathy. Evolution: The Basics examines the role of evolution in current debates and discusses the possible future developments in the field. This book is invaluable reading for all students and individuals seeking to understand the wide ranging sphere of evolutionary theory.

Animal evolution has always been at the core of Biology, but even today many fundamental questions remain open. The field of animal ‘evo-devo’ is leveraging recent technical and conceptual advances in development, paleontology, genomics and transcriptomics to propose radically different answers to traditional evolutionary controversies. This book is divided into four parts, each of which approaches animal evolution from a different perspective. The first part (chapters 2 and 3) investigates how new sources of evidence have changed conventional views of animal origins, while the second (chapters 4–8) addresses the connection between embryogenesis and evolution, and the genesis of cellular, tissue and morphological diversity. The third part (chapters 9 and 10) investigates how big data in molecular biology is transforming our understanding of the mechanisms governing morphological change in animals. In closing, the fourth part (chapters 11–13) explores new theoretical and conceptual approaches to animal evolution. ‘Old questions and young approaches to animal evolution’ offers a comprehensive and updated view of animal evolutionary biology that will serve both as a first step into this fascinating field for students and university educators, and as a review of complementary approaches for researchers.

Sexual selection, or the struggle for mates, was of considerable strategic importance to Darwin s theory of evolution as he first outlined it in the "Origin of Species," and later, in the "Descent of Man," it took on a much wider role. There, Darwin s exhaustive elaboration of sexual selection throughout the animal kingdom was directed to substantiating his view that human racial and sexual differences, not just physical differences but certain mental and moral differences, had evolved primarily through the action of sexual selection. It was the culmination of a lifetime of intellectual effort and commitment. Yet even though he argued its validity with a great array of critics, sexual selection went into abeyance with Darwin s death, not to be revived until late in the twentieth century, and even today it remains a controversial theory. In unfurling the history of sexual selection, Evelleen Richards brings to vivid life Darwin the man, not the myth, and the social and intellectual roots of his theory building."

Does the inheritance of acquired characteristics play a significant role in evolution? In this book, Eva Jablonka and Marion J. Lamb attempt to answer that question with an original, provocative exploration of the nature and origin of hereditary variations. Starting with a historical account of Lamarck's ideas and the reasons they have fallen in disrepute, the authors go on to challenge the prevailing assumption that all heritable variation is random and the result of variation in DNA base sequences. They also detail recent breakthroughs in our understanding of the molecular mechanisms underlying inheritance--including several pathways not envisioned by classical population genetics--and argue that these advances need to be more fully incorporated into mainstream evolutionary theory. Throughout, the book offers a new look at the evidence for and against the hereditability of environmentally induced changes, and addresses timely questions about the importance of non-Mendelian inheritance. A glossary and extensive list of references round out the book. Urging a reconsideration of the present DNA-centric view prevalent in the field, Epigentic Inheritance and Evolution will make fascinating and important reading for students and researchers in evolution, genetics, ecology, molecular biology, developmental biology, and the history and philosophy of science.
