Available in PDF, EPUB and Kindle. Book excerpt: The evolutionist Ernst Mayr considered August Weismann “one of the great biologists of all time.” Yet the man who formulated the germ plasm theory—that inheritance is transmitted solely through the nuclei of the egg and sperm cells—has not received an in-depth historical examination. August Weismann reintroduces readers to a towering figure in the life sciences. In this first full-length biography, Frederick Churchill situates Weismann in the swirling intellectual currents of his era and demonstrates how his work paved the way for the modern synthesis of genetics and evolution in the twentieth century. In 1859 Darwin’s tantalizing new idea stirred up a great deal of activity and turmoil in the scientific world, to a large extent because the underlying biological mechanisms of evolution through natural selection had not yet been worked out. Weismann’s achievement was to unite natural history, embryology, and cell biology under the capacious dome of evolutionary theory. In his major work on the germ plasm (1892), which established the material basis of heredity in the “germ cells,” Weismann delivered a crushing blow to Lamarck’s concept of the inheritance of acquired traits. In this deeply researched biography, Churchill explains the development of Weismann’s pioneering work based on cytology and embryology and opens up an expanded history of biology from 1859 to 1914. August Weismann is sure to become the definitive account of an extraordinary life and career.

Available in PDF, EPUB and Kindle. Book excerpt: In this lecture, the author points out that Nägeli's perspective on the evolution of the organic world has always struck him as surprising. He assumed that it had arisen from inherent internal forces and that external influences had only played a secondary and unimportant role, improving and modifying but not determining. This astute thinker stated unequivocally that, in his opinion, the course of development would have resulted in roughly the same outcome even if life conditions had remained unchanged since the beginning.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first of a pair of volumes by Jonathan Hodge, collecting all his most innovative, revisionist and influential papers on Charles Darwin and on the longer run of theories about origins and species from ancient times to the present. The focus in this volume is on the diversity of theories among such pre-Darwinian authors as Lamarck and Whewell, and on developments in the theory of natural selection since Darwin. Plato's Timaeus, the Biblical Genesis and any current textbook of evolutionary biology are all, it may well seem, on this same enduring topic: origins and species. However, even among classical authors, there were fundamental disagreements: the ontology and cosmogony of the Greek atomists were deeply opposed to Plato's; and, in the millennia since, the ontological and cosmogonical contexts for theories about origins and species have never settled into any unifying consensus. While the structure of Darwinian theory may be today broadly what it was in Darwin's own argumentation, controversy continues over the old issues about order, chance, necessity and purpose in the living world and the wider universe as a whole. The historical and philosophical papers collected in this volume, and in the companion volume devoted to Darwin's theorising, seek to clarify the major continuities and discontinuities in the long run of thinking about origins and species.

Download or read book Evolutionary Biology: Contemporary and Historical Reflections Upon Core Theory written by Thomas E. Dickins and published by Springer Nature. This book was released on 2023-04-09 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is reflecting upon core theories in evolutionary biology – in a historical as well as contemporary context. It exposes the main areas of interest for discussion, but more importantly draws together hypotheses and future research directions. The Modern Synthesis (MS), sometimes referred to as Standard Evolutionary Theory (SET), in evolutionary biology has been well documented and discussed, but was also critically scrutinized over the last decade. Researchers from diverse disciplinary backgrounds have claimed that there is a need for an extension to that theory, and have called for an Extended Evolutionary Synthesis (EES). The book starts with an introductory chapter that summarizes the main points of the EES claim and indicates where those points receive treatment later in the book. This introduction to the subjects can either serve as an initiation for readers new to the debate, or as a guide for those looking to pursue particular lines of enquiry. The following chapters are organized around historical perspectives, theoretical and philosophical approaches and the use of specific biological models to inspect core ideas. Both empirical and theoretical contributions have been included. The majority of chapters are addressing various aspects of the EES position, and reflecting upon the MS. Some of the chapters take historical perspectives, analyzing various details of the MS and EES claims. Others offer theoretical and philosophical analyses of the debate, or take contemporary findings in biology and discuss those findings and their possible theoretical interpretations. All of the chapters draw upon actual biology to make their points. This book is written by practicing biologists and behavioral biologists, historians and philosophers - many of them working in interdisciplinary fields. It is a valuable resource for historians and philosophers of biology as well as for biologists.
