Available in PDF, EPUB and Kindle. Book excerpt: An innovative view of the role of fitness concepts in evolutionary theory. Natural selection is one of the factors responsible for changes in biological populations. Some traits or organisms are fitter than others, and natural selection occurs when there are changes in the distribution of traits in populations because of fitness differences. Many philosophers of biology insist that a trait’s fitness should be defined as an average of the fitnesses of individual members of the population that have the trait. Marshall Abrams argues convincingly against this widespread approach. As he shows, it conflicts with the roles that fitness is supposed to play in evolutionary theory and with the ways that evolutionary biologists use fitness concepts in empirical research. The assumption that a causal kind of fitness is fundamentally a property of actual individuals has resulted in unnecessary philosophical puzzles and years of debate. Abrams came to see that the fitnesses of traits that are the basis of natural selection cannot be defined in terms of the fitnesses of actual members of populations, as philosophers of biology often claim. Rather, it is an overall population-environment system—not actual, particular organisms living in particular environmental conditions—that is the basis of trait fitnesses. Abrams argues that by distinguishing different classes of fitness concepts and the roles they play in the practice of evolutionary biology, we can see that evolutionary biologists’ diverse uses of fitness concepts make sense together and are consistent with the idea that fitness differences cause evolution. Abrams’s insight has broad significance, for it provides a general framework for thinking about the metaphysics of biological evolution and its relations to empirical research. As such, it is a game-changing book for philosophers of biology, biologists who want deeper insight into the nature of evolution, and anyone interested in the applied philosophy of probability.

Download or read book Chance in Evolution written by Grant Ramsey and published by University of Chicago Press. This book was released on 2016-10-25 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book to synthesize scientific and philosophical work on chance, this edited volume brings together leading biologists, philosophers of science, and historians of science, who collectively explore the role that chance plays or doesn t play, as the case may be in evolution. The first part of the volume places chance in historical context and explores how Darwin, along with his contemporaries, understood chance in addition to its related concepts; how these various concepts changed as Darwin s theory of evolution by natural selection developed into the Modern Synthesis; and how the chanciness of Darwinian theory affected theological resistance to it. The second part explores the importance of chance in current evolutionary theory. The third and final part focuses on recent empirical work in microbial experimental evolution and paleobiology, with the goal of determining how much of a role chance and contingency has played and continues to play in the history of life. The volume s final chapter investigates the perennial topic of chance in human evolution, beginning with the pre-Darwinian, theistic view that humans are at the pinnacle of the natural world and ending with the Darwinian view, which leaves no room for biological progress. It ultimately presents a more tempered view of biological progress and suggests that although our arrival on the evolutionary scene might not have been inevitable, it might not have been due to chance alone.

Download or read book The Rise of Chance in Evolutionary Theory written by Charles H. Pence and published by Academic Press. This book was released on 2021-11-25 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rise of Chance in Evolutionary Theory: A Pompous Parade of Arithmetic explores a pivotal conceptual moment in the history of evolutionary theory: the development of its extensive reliance on a wide array of concepts of chance. It tells the history of a methodological and conceptual development that reshaped our approach to natural selection over a century, ranging from Darwin’s earliest notebooks in the 1830s to the early years of the Modern Synthesis in the 1930s. Far from being a “pompous parade of arithmetic, as one early critic argued, evolution transformed during this period to make these conceptual and technical tools indispensable. This book charts the role of chance in evolutionary theory from its beginnings to the earliest days of modern evolutionary theory, making it an ideal resource for evolutionary biologists, historians, philosophers, and researchers in science studies or biological statistics. Analyzes contributions of key historical figures and assesses how and why these “foundational conclusions were reached by original evolutionary biologists, including Darwin, Galton, Pearson, and more Describes the journey of the role of chance in evolutionary theory and illuminates our contemporary understanding Presents the historical narrative in a non-technical way, focusing on the conceptual structure of evolutionary theory
Download or read book The Logic of Chance written by Eugene V. Koonin and published by FT Press. This book was released on 2011-06-23 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Logic of Chance offers a reappraisal and a new synthesis of theories, concepts, and hypotheses on the key aspects of the evolution of life on earth in light of comparative genomics and systems biology. The author presents many specific examples from systems and comparative genomic analysis to begin to build a new, much more detailed, complex, and realistic picture of evolution. The book examines a broad range of topics in evolutionary biology including the inadequacy of natural selection and adaptation as the only or even the main mode of evolution; the key role of horizontal gene transfer in evolution and the consequent overhaul of the Tree of Life concept; the central, underappreciated evolutionary importance of viruses; the origin of eukaryotes as a result of endosymbiosis; the concomitant origin of cells and viruses on the primordial earth; universal dependences between genomic and molecular-phenomic variables; and the evolving landscape of constraints that shape the evolution of genomes and molecular phenomes. "Koonin's account of viral and pre-eukaryotic evolution is undoubtedly up-to-date. His "mega views" of evolution (given what was said above) and his cosmological musings, on the other hand, are interesting reading."

Download or read book Evolutionary Theory written by Niles Eldredge and published by University of Chicago Press. This book was released on 2016-09-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The natural world is infinitely complex and hierarchically structured, with smaller units forming the components of progressively larger systems: molecules make up cells, cells comprise tissues and organs that are, in turn, parts of individual organisms, which are united into populations and integrated into yet more encompassing ecosystems. In the face of such awe-inspiring complexity, there is a need for a comprehensive, non-reductionist evolutionary theory. Having emerged at the crossroads of paleobiology, genetics, and developmental biology, the hierarchical approach to evolution provides a unifying perspective on the natural world and offers an operational framework for scientists seeking to understand the way complex biological systems work and evolve. Coedited by one of the founders of hierarchy theory and featuring a diverse and renowned group of contributors, this volume provides an integrated, comprehensive, cutting-edge introduction to the hierarchy theory of evolution. From sweeping historical reviews to philosophical pieces, theoretical essays, and strictly empirical chapters, it reveals hierarchy theory as a vibrant field of scientific enterprise that holds promise for unification across the life sciences and offers new venues of empirical and theoretical research. Stretching from molecules to the biosphere, hierarchy theory aims to provide an all-encompassing understanding of evolution and—with this first collection devoted entirely to the concept—will help make transparent the fundamental patterns that propel living systems.
Download or read book Adaptation and Natural Selection written by George Christopher Williams and published by Princeton University Press. This book was released on 2018-10-30 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.

Download or read book Improbable Destinies written by Jonathan B. Losos and published by Penguin. This book was released on 2018-08-07 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

Download or read book The Nature of Selection written by Elliott Sober and published by University of Chicago Press. This book was released on 2014-12-10 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nature of Selection is a straightforward, self-contained introduction to philosophical and biological problems in evolutionary theory. It presents a powerful analysis of the evolutionary concepts of natural selection, fitness, and adaptation and clarifies controversial issues concerning altruism, group selection, and the idea that organisms are survival machines built for the good of the genes that inhabit them. "Sober's is the answering philosophical voice, the voice of a first-rate philosopher and a knowledgeable student of contemporary evolutionary theory. His book merits broad attention among both communities. It should also inspire others to continue the conversation."-Philip Kitcher, Nature "Elliott Sober has made extraordinarily important contributions to our understanding of biological problems in evolutionary biology and causality. The Nature of Selection is a major contribution to understanding epistemological problems in evolutionary theory. I predict that it will have a long lasting place in the literature."-Richard C. Lewontin
Download or read book Natural Selection written by George C. Williams and published by Oxford University Press. This book was released on 1992-10-01 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, George C. Williams--one of evolutionary biology's most distinguished scholars--examines the mechanisms and meaning of natural selection in evolution. Williams offers his own perspective on modern evolutionary theory, including discussions of the gene as the unit of selection, clade selection and macroevolution, diversity within and among populations, stasis, and other timely and provocative topics. In dealing with the levels-of-selection controversy, he urges a pervasive form of the replicator-vehicle distinction. Natural selection, he argues, takes place in the separate domains of information and matter. Levels-of-selection questions, consequently, require different theoretical devices depending on the domains being discussed. In addressing these topics, Williams presents a synthesis of his three decades of research and creative thought which have contributed greatly to evolutionary biology in this century.

Download or read book Evolutionary Theory written by Sean H. Rice and published by Sinauer Associates Incorporated. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary Theory is for graduate students, researchers, and advanced undergraduates who want an understanding of the mathematical and biological reasoning that underlies evolutionary theory. The book covers all of the major theoretical approaches used to study the mechanics of evolution, including classical one- and two-locus models, diffusion theory, coalescent theory, quantitative genetics, and game theory. There are also chapters on theoretical approaches to the evolution of development and on multilevel selection theory. Each subject is illustrated by focusing on those results that have the greatest power to influence the way that we think about how evolution works. These major results are developed in detail, with many accompanying illustrations, showing exactly how they are derived and how the mathematics relates to the biological insights that they yield. In this way, the reader learns something of the actual machinery of different branches of theory while gaining a deeper understanding of the evolutionary process. Roughly half of the book focuses on gene-based models, the other half being concerned with general phenotype-based theory. Throughout, emphasis is placed on the fundamental relationships between the different branches of theory, illustrating how all of these branches are united by a few basic, universal, principles. The only mathematical background assumed is basic calculus. More advanced mathematical methods are explained, with the help of an extensive appendix, when they are needed.
Download or read book Chance and Necessity written by Jacques Monod and published by . This book was released on 1971 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A philosophical statement whose explicit intention is to sweep away as both false and dangerous the 'animist' conception of man that has dominated virtually all Western world views from those of primitive cultures to those of dialectical materialists. Monod bases his argument on the evidence of modern biology, which shows, indisputably, that man is the product of chance genetic mutation. He draws upon what we now know about genetic structure (and on what we can theorize) to suggest an entirely new way of looking at ourselves. He argues that objective scientific knowledge, the only knowledge we can rely on, denies the concepts of destiny or evolutionary purpose that underlie traditional philosophies; and he contends that the persistence of those concepts is responsible for the intensifying schizophrenia of a world that accepts, and lives by, the fruits of science while refusing to face its momentous moral implications"--From publisher description.
