Book Synopsis Evolutionary Patterns by : Alan H. Cheetham

Download or read book Evolutionary Patterns written by Alan H. Cheetham. This book was released on 2001-08. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Evolutionary Phonology by : Juliette Blevins

Download or read book Evolutionary Phonology written by Juliette Blevins. This book was released on 2004-07-22. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary Phonology is a theory of sound patterns which synthesizes results in historical linguistics, phonetics and phonological theory. In this book, Juliette Blevins explores the nature of sounds patterns and sound change in human language over the past 7000–8000 years, the time depth for which the comparative method is reasonably reliable. This book presents an approach to the problem of how genetically unrelated languages, from families as far apart as Native American, Australian Aboriginal, Austronesian and Indo-European, can often show similar sound patterns, and also tackles the converse problem of why there are notable exceptions to most of the patterns that are often regarded as universal tendencies or constraints. It argues that in both cases, a formal model of sound change that integrates phonetic variation and patterns of misperception can account for attested sound systems without reference to markedness or naturalness within the synchronic grammar.

Book Synopsis Evolutionary Patterns and Processes by : D. R. Lees

Download or read book Evolutionary Patterns and Processes written by D. R. Lees. This book was released on 1993. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Emergence of Whales written by J.G.M. Thewissen. This book was released on 2013-11-11. Available in PDF, EPUB and Kindle. Book excerpt: Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Download or read book Systematics and the Fossil Record written by Andrew B. Smith. This book was released on 2009-07-15. Available in PDF, EPUB and Kindle. Book excerpt: This new text sets out to establish the key role played by systematics in deciphering patterns of evolution from the fossil record. It begins by considering the nature of the species in the fossil record and then outlines recent advances in the methodology used to establish phylogenetics relationships, stressing why fossil evidence can be crucial. The way species are grouped into higher taxa, and how this affects their utility in evolutionary studies is also discussed. Because the fossil record abounds with sampling and preservational biases, the book emphasizes that observed patterns can rarely be taken at face value. It is argued that evolutionary trees, constructed from combining phylogenetic and biostratigraphic data, provide the best approach for investigating patterns of evolution through geologic time. The only integrated text covering the study of evolutionary patterns from a phylogenetic stance.
