On the Origin of Phyla

On the Origin of Phyla PDF Author: James W. Valentine
Publisher: University of Chicago Press
ISBN: 0226845486
Category : Science
Languages : en
Pages : 639

Book Description
Owing its inspiration and title to On the Origin of Species, James W. Valentine's ambitious book synthesizes and applies the vast treasury of theory and research collected in the century and a half since Darwin's time. By investigating the origins of life's diversity, Valentine unlocks the mystery of the origin of phyla. One of the twentieth century's most distinguished paleobiologists, Valentine here integrates data from molecular genetics, evolutionary developmental biology, embryology, comparative morphology, and paleontology into an analysis of interest to scholars from any of these fields. He begins by examining the sorts of evidence that can be gleaned from fossils, molecules, and morphology, then reviews and compares the basic morphology and development of animal phyla, emphasizing the important design elements found in the bodyplans of both living and extinct phyla. Finally, Valentine undertakes the monumental task of developing models to explain the origin and early diversification of animal phyla, as well as their later evolutionary patterns. Truly a magnum opus, On the Origin of Phyla will take its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come. "A magisterial compendium . . . . Valentine offers a judicious evaluation of an astonishing array of evidence."—Richard Fortey, New Scientist "Truly a magnum opus, On the Origin of Phyla has already taken its place as one of the classic scientific texts of the twentieth century, affecting the work of paleontologists, morphologists, and developmental, molecular, and evolutionary biologists for decades to come."—Ethology, Ecology & Evolution "Valentine is one of the Renaissance minds of our time. . . . Darwin wisely called his best-known work On the Origin of the Species; the origin of the phyla is an even stickier problem, and Valentine deserves credit for tackling it at such breadth . . . . A magnificient book."—Stefan Bengtson, Nature

The Origins of Agriculture

The Origins of Agriculture PDF Author: David Rindos
Publisher: Academic Press
ISBN: 148326954X
Category : Technology & Engineering
Languages : en
Pages : 344

Book Description
The Origins of Agriculture: An Evolutionary Perspective presents an alternative approach to understanding cultural variation and change. It aims to demonstrate that domestication and the origin of agricultural systems are best understood by attempting to explicate the evolutionary forces that affected that development of domesticates and agricultural systems. The book begins by discussing cultural change, the domestication of plants, and the origin of agricultural systems in the most general of terms. It considers Darwinism in some depth, concentrating on the relationship between natural selection and cultural change. Subsequent chapters examine the world of domestication and agriculture and present a series of concepts that may permit a more natural explanation for these processes. These include concepts such as incidental domestication, specialized domestication, and agricultural domestication. The final two chapters present models for the origin and spread of agricultural systems based upon Darwinian evolutionary theory.

Insect Development and Evolution

Insect Development and Evolution PDF Author: Bruce S. Heming
Publisher: Cornell University Press
ISBN: 1501720759
Category : Science
Languages : en
Pages : 464

Book Description
Life scientists are increasingly drawn to the study of comparative evolutionary biology. Insect Development and Evolution is the first synthesis of knowledge of insect development within an evolutionary framework and the first to survey the genetic, molecular, and whole organism literature. Bruce S. Heming provides a detailed introduction to the embryonic and postembryonic development of insects. Topics include:* reproductive systems,* male and female gametogenesis,* sperm transfer and use,* fertilization,* sex determination,* parthenogenesis,* embryogenesis,* postembryogenesis,* hormones,* and the role of ontogeny in insect evolution.Summaries for each of these topics cover structural events; comparative aspects (inserted on a phylogeny of the insect orders); and hormonal, genetic, and molecular causal analyses.Insect Development and Evolution treats examples throughout the hexapods with frequent reference to the evolution and development of other invertebrates. It also compares insects to vertebrates and places insect development into context with fossil evidence and earth history. Heming's book will become an essential tool for students and teachers of entomology. It will also interest insect systematists and paleontologists, insect behavioral ecologists, insect pathologists, applied entomologists, developmental and invertebrate biologists, and all scientists who use Drosophila as a model organism.

Causes of Evolution

Causes of Evolution PDF Author: Robert M. Ross
Publisher: University of Chicago Press
ISBN: 0226728242
Category : Science
Languages : en
Pages : 496

Book Description
By studying evolution across geological time, paleontologists gain a perspective that sometimes complements and sometimes conflicts with views based solely on studies of extant species. The contributors to Causes of Evolution consider whether factors exerting major influences on evolution are biotic or abiotic, intrinsic or extrinsic. Causes of Evolution presents a broad sampling of paleontological research programs encompassing vertebrates, invertebrates, and vascular plants; empirical work and theoretical models; organisms ranging in age from Cambrian to Recent; and temporal scales from ecological time to hundreds of millions of years. The diverse array of research styles and opinions presented will acquaint scientists in related fields with the strengths and weaknesses of paleontology as an approach to evolutionary studies and will give evolutionary biologists of every stripe new bases for evaluating the scope and bias of their own work.

Patterns and Processes in the History of Life

Patterns and Processes in the History of Life PDF Author: D.M. Raup
Publisher: Springer Science & Business Media
ISBN: 3642708315
Category : Medical
Languages : en
Pages : 448

Book Description
Hypothesis testing is not a straightforward matter in the fossil record and here, too interactions with biology can be extremely profitable. Quite simply, predictions regarding long-term consequences of processes observed in liv ing organisms can be tested directly using paleontological data if those liv ing organisms have an adequate fossil record, thus avoiding the pitfalls of extrapolative approaches. We hope to see a burgeoning of this interactive effort in the coming years. Framing and testing of hypotheses in paleon tological subjects inevitably raises the problem of inferring process from pattern, and the consideration and elimination of a broad range of rival hy is an essential procedure here. In a historical science such as potheses paleontology, the problem often arises that the events that are of most in terest are unique in the history of life. For example, replication of the metazoan radiation at the beginning of the Cambrian is not feasible. How ever, decomposition of such problems into component hypotheses may at least in part alleviate this difficulty. For example, hypotheses built upon the role of species packing might be tested by comparing evolutionary dy namics (both morphological and taxonomic) during another global diversi fication, such as the biotic rebound from the end-Permian extinction, which removed perhaps 95% of the marine species (see Valentine, this volume). The subject of extinction, and mass extinction in particular, has become important in both paleobiology and biology.
