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.

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.

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.

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.

In the past years, much work has been carried out on either life-history evolu tion or structure and function of food webs. However, most studies dealt with only one of these areas and often touched upon the other only marginally. In this volume, we try to synthesize aspects of both disciplines and will concen trate on how the interactions between organisms depend on their life-history strategies. Since this is a very comprehensive topic, this volume will focus on vertical interactions to remain within a clearly arranged field. We present some scenaria based on life-history variation of resource and consumer, and show how particular patterns of life-history combinations will lead to particular patterns in trophic relationships. We want to deal with the selective forces underlying these patterns: the degree of specificity of the consumers deter mines the dependence on its resource, and its adaptation to the spatial and temporal availability of the resource. In this respect, the spatial structure of the resource and its "quality" may play an important role. The impact of natural enemies is another important selective force which may influence the evolu tion of interactions between species and the structure of communities. Here, the acquirement of an enemy-free space may provide selective adavantages. The importance of the impact of enemies is also expressed by the development of numerous and sometimes very subtle defense strategies. This will be dem onstrated especially for various aspects of chemical ecology.

The prerequisite to investigating the underlying causes behind mass extinction is a profound understanding of the evolutionary history of both living and dead species. It is especially important to appreciate the significance of such studies in extinct organisms; especially in organisms that were abundant in a certain geologic era, but have subsequently dwindled or become extinct. Such studies should help to accurately evaluate patterns of evolution in extinct species lineages and help predict the same in its modern analogs. The book includes cutting edge research in evolutionary biology that should serve as a starting point for conservation.

Ever since the pioneering work of Darwin and Wallace, evolutionary biologists have attempted to understand the evolutionary dynamics of genetic systems. A range of theories on evolutionary ratesfrom static to gradual to punctuated to quantumhave been developed, primarily by comparing morphological changes over geological timescales as described in the fossil record. Recent studies, however, are beginning to change the way that we view evolutionary patterns and processes. New paleontological, experimental, molecular, and genomic investigations are providing a tremendous amount of novel data and fresh perspectives, offering valuable insights on the rates of evolutionary change, particularly in fast-evolving genetic systems. Rapidly Evolving Genes and Genetic Systems captures these recent exciting developments across a broad range of morphological, molecular, cellular, developmental, and genetic investigations in both natural and experimental populations over a diversity of life forms. The book provides a fascinating series of case studies that exemplify rapid evolution, and showcases the diversity of rapidly evolving genes and genetic systems, emphasizing the extremely important roles that they play in adaptation, speciation, and the generation and maintenance of a diversity of biological traits and properties. This exciting collection showcases the latest research of more than 50 eminent evolutionary biologists. It will be suitable for senior undergraduate students, graduate students, researchers, and for all those interested in the study of evolution.
