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.

Terrestrial Ecosystems Through Time


Book Description

Breathtaking in scope, this is the first survey of the entire ecological history of life on land—from the earliest traces of terrestrial organisms over 400 million years ago to the beginning of human agriculture. By providing myriad insights into the unique ecological information contained in the fossil record, it establishes a new and ambitious basis for the study of evolutionary paleoecology of land ecosystems. A joint undertaking of the Evolution of Terrestrial Ecosystems Consortium at the National Museum of Natural History, Smithsonian Institution, and twenty-six additional researchers, this book begins with four chapters that lay out the theoretical background and methodology of the science of evolutionary paleoecology. Included are a comprehensive review of the taphonomy and paleoenvironmental settings of fossil deposits as well as guidelines for developing ecological characterizations of extinct organisms and the communities in which they lived. The remaining three chapters treat the history of terrestrial ecosystems through geological time, emphasizing how ecological interactions have changed, the rate and tempo of ecosystem change, the role of exogenous "forcing factors" in generating ecological change, and the effect of ecological factors on the evolution of biological diversity. The six principal authors of this volume are all associated with the Evolution of Terrestrial Ecosystems program at the National Museum of Natural History, Smithsonian Institution.

Bryozoan Evolution


Book Description

The authors argue that the growth pattern and form of the colony in many bryozoans is an adaptive strategy rather than a stable genetic character. "Bryozoan Evolution is profusely illustrated and has a bibliography of over 400 titles. It will find an appreciative audience of paleontologists, invertebrate zoologists, and ecologists thanks to its innovative and detailed evaluations of the roles of ecology, adaptive and functional morphology, life histories, biomechanics, developmental constraints, and chance on the evolution of the marine taxa of this speciose group."—Russel L. Zimmer, Science "This book is an excellent source of information on the functional morphology and variety of colonial architecture in bryozoans, very well illustrated, and worth reading at least twice."-Robert L. Anstey, Paleobiology "Even as one of the converted, I found the book a stimulating combination of paleobiology and ecology. In many ways it is a 'teaser'-the authors suggest a number of interesting hypotheses, and can test only some of them. Perhaps most important, McKinney and Jackson provide a plethora of fascinating ideas and examples that demonstrate the potential of this group of animals, and that should stimulate more work."-Michael S. Keough, TREE "This stimulating book is sure to promote further interest in bryozoans. It will appeal to biologists and paleontologists alike."-Paul Taylor, Times Higher Education Supplement







An Inquiry Into the Ethnic Resolution of Mesolithic Regional Groups


Book Description

Recent Western European Mesolithic research has greatly augmented our understanding of the time and space parameters of material derived from settlements. Perusals of those regularities have led to a renewed scrutiny of the ethnographic literature in an attempt to perceive the resulting temporal and spatial units as anthropologically relevant regional groups. The proposition that the breeding population was identical to the ethnic identity of the participants is untenable. After a review of the physical anthropological composition of that population and its forms of social and spatial organization, the emic relevance of decorative ornamentation and costume is established in terms of society-specific styles. Proceeding from a series of tenets of processual ethnographic analogy, the ornaments extant in the post- glacial hunter-fisher-gatherer cultures of Western Europe are examined for their formal properties and time and space parameters. By means of an explicit set of postulates they are tested for the identification, definition and territorial placement of mesolithic social, ethnic and linguistic groups.







The Geology of Central Europe: Mesozoic and Cenozoic


Book Description

Volume 2 provides an overview of the Mesozoic and Cenozoic evolution of Central Europe. This period commenced with the destruction of Pangaea and ended with the formation of the Alps and Carpathians and the subsequent Ice Ages. Separate summary chapters on the Permian to Cretaceous tectonics and the Alpine evolution are also included. The final chapter provides an overview of the fossils fuels, ore and industrial minerals in the region.
