Evolutionary Patterns and Processes


Book Description

Evolution is the central theme of all biology. Researcarcch in the many branches of evolutionary study continues to flourish. This book, based on a symposium of the Linnean Society, discusses the diversity in currentevolutionary research. It approaches the subject ambitiously and from several angles, bringing ttogether eminent authors from a variety of disciplines paleontologists traditionally with a macroevolutionary bias, neontologists concentrating on microevolutionary processes, and those studying the very essence ofsses and those studying the very essence of evolution the process of speciation in living organisms. Evolutionary Patterns and Processes will appeal to a broad spectrum of professional biologistsworking in such fields as paleontology, population biology, and evolutionary genetics. Biologists will enjoy chapters by Stephen J. Gould, discovering in the much earlier work of Hugo de Vries parallels with his ideas on punctuational evolution; Guy Bush,considering why there are so many small animals; Peter Sheldon, examining detailed fossil trilobite sequences for evidence of microevolutionary processes and considering models of speciation; as well as others dealing with cytological, ecological, and behavioral processes leading to the evolution of new species.

Evolutionary Patterns


Book Description

With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development. The contributors are Ann F. Budd, Efstathia Bura, Leo W. Buss, Mike Foote, Jörn Geister, Stephen Jay Gould, Eckart Hâkansson, Jean-Georges Harmelin, Lee-Ann C. Hayek, Jeremy B. C. Jackson, Kenneth G. Johnson, Nancy Knowlton, Scott Lidgard, Frank K. McKinney, Daniel W. McShea, Ross H. Nehm, Beth Okamura, John M. Pandolfi, Paul D. Taylor, and Erik Thomsen.




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




Eco-Evolutionary Dynamics


Book Description

The theme of this volume is to discuss Eco-evolutionary Dynamics. Updates and informs the reader on the latest research findings Written by leading experts in the field Highlights areas for future investigation




Patterns and Processes of Vertebrate Evolution


Book Description

The factors that influenced the evolution of the vertebrates are compared with the importance of variation and selection that Darwin emphasised in this broad study of the patterns and forces of evolutionary change.




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.







Microevolution Rate, Pattern, Process


Book Description

From guppies to Galapagos finches and from adaptive landscapes to haldanes, this compilation of contributed works provides reviews, perspectives, theoretical models, statistical developments, and empirical demonstrations exploring the tempo and mode of microevolution on contemporary to geological time scales. New developments, and reviews, of classic and novel empirical systems demonstrate the strength and diversity of evolutionary processes producing biodiversity within species. Perspectives and theoretical insights expand these empirical observations to explore patterns and mechanisms of microevolution, methods for its quantification, and implications for the evolution of biodiversity on other scales. This diverse assemblage of manuscripts is aimed at professionals, graduate students, and advanced undergraduates who desire a timely synthesis of current knowledge, an illustration of exciting new directions, and a springboard for future investigations in the study of microevolution in the wild.
