Evolution


Book Description

This text is about the central role of evolution in shaping the nature and diversity of the living world. It describes the processes of natural selection, how adaptations arise, and how new species form, as well as summarizing the evidence for evolution







Culture and the Evolutionary Process


Book Description

How do biological, psychological, sociological, and cultural factors combine to change societies over the long run? Boyd and Richerson explore how genetic and cultural factors interact, under the influence of evolutionary forces, to produce the diversity we see in human cultures. Using methods developed by population biologists, they propose a theory of cultural evolution that is an original and fair-minded alternative to the sociobiology debate.




Evolutionary processes and theory


Book Description

Evolutionary Processes and Theory contains the proceedings of a workshop held in Israel in March 1985. Contributors explore evolutionary processes and theory and highlight advances in knowledge concerning differentiation, metabolic and immunological mechanisms, and the molecular biology of the genome. Issues that are being debated are also considered, including the origin and evolution of sexual systems, the genetics of altruism, and general forms and levels of social evolution. This volume is organized into six sections encompassing 33 chapters and begins with an overview of the evolutionary problems of molecular biology. Some chapters are devoted to topics such as the role of gene regulation in evolutionary processes; the structural diversity and evolution of intermediate filament proteins; and adaptation and evolution in the immune system. The next section examines the tempo and mode of molecular evolution, including that of hybrid dysgenesis systems, as well as the statistical aspects of the molecular clock. Later chapters focus on DNA and protein sequences; sexual selection and speciation; and the relation between speciation mechanisms and macroevolutionary patterns. The book also methodically explains population genetics, with particular reference to the altruistic behavior in sibling groups with unrelated intruders, the endosperm evolution in higher plants, and the evolutionary aspects of sexual reproduction in predominantly asexual populations. This book will be of interest to geneticists and molecular biologists.




Evolutionary Theory


Book Description

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.




Chance in Evolution


Book Description

This illuminating volume explores the effects of chance on evolution, covering diverse perspectives from scientists, philosophers, and historians. The evolution of species, from single-celled organisms to multicellular animals and plants, is the result of a long and highly chancy history. But how profoundly has chance shaped life on earth? And what, precisely, do we mean by chance? Bringing together biologists, philosophers of science, and historians of science, Chance in Evolution is the first book to untangle the far-reaching effects of chance, contingency, and randomness on the evolution of life. The book begins by placing chance in historical context, starting with the ancients and moving through Darwin to contemporary biology. It documents the shifts in our understanding of chance as Darwin’s theory of evolution developed into the modern synthesis, and how the acceptance of chance in Darwinian theory affected theological resistance to it. Other chapters discuss how chance relates to the concepts of genetic drift, mutation, and parallel evolution—as well as recent work in paleobiology and the experimental evolution of microbes. By engaging in collaboration across biology, history, philosophy, and theology, this book offers a comprehensive overview both of the history of chance in evolution and of our current understanding of the impact of chance on life.




Information and Meaning in Evolutionary Processes


Book Description

This book is intended to help transform epistemology - the traditional study of knowledge - into a rigorous discipline by removing conceptual roadblocks and developing formal tools required for a fully naturalized epistemology. The evolutionary approach which Harms favours begins with the common observation that if our senses and reasoning were not reliable, then natural selection would have eliminated them long ago. The challenge for some time has been how to transform these informal musings about evolutionary epistemology into a rigorous theoretical discipline capable of complementing current scientific studies of the evolution of cognition with a philosophically defensible account of meaning and justification.




Evolutionary Theory


Book Description

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.




Evolutionary Processes and Organizational Adaptation


Book Description

How do firms adapt? Is it through rational choice and intentionality, or rather a process of evolutionary dynamics? Using the ideas of Gregor Mendel as a touchstone, this book aims to construct a middle-ground between these two conceptions and provide a new framework for understanding the adaptive dynamics of organizations.




Technological Innovation as an Evolutionary Process


Book Description

Ground-breaking yet non-technical analysis of the analogy that technological artefacts 'evolve' like biological organisms.
