Book Synopsis Palaeobiology of Angiosperm Origins by : Norman F. Hughes
Download or read book Palaeobiology of Angiosperm Origins written by Norman F. Hughes and published by CUP Archive. This book was released on 1976-01-29 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mr Hughes argues that approaches (previous to 1976) to the evolutionary origin and early history of or flowering plants have been inadequate and misleading. He suggests that the date is in the Cretaceous period and there is a good chance of ancestors being found if other fossil plants of that period are studied.

Available in PDF, EPUB and Kindle. Book excerpt: Angiosperms are the most diversi ed plant group in the world, being represented by ca 300,000 species in about 400 families. Like all of Life, including ourselves, they have had their own history and gone through many evolutionary stages before they arrived at their current forms. The origin of Angiospermae ( owering plants) has been the subject of much dispute because this is a key event in the history of life, and has a far-reaching in uence on our understanding of relationships among seed plants as a whole as well as within the angiosperms. Until recently most of palae- otanists recognized angiosperms only from the Cretaceous and younger strata. This contradicts the results of molecular analyses. I have been working on Mesozoic fossil plants for the past two decades, during which time I have studied a number of fossil plants. Some of these fossil plants have been published as Jurassic angiosperms, and, unsurprisingly, many questions and doubts have been raised about them. These questions need to be addressed se- ously and journal papers do not provide suf cient space to compare and relate these early angiosperms. In this book these pioneer angiosperms are documented in detail, sometimes with new specimens not studied before. Also, I propose a de nition of angiosperms that could be adopted in palaeobotany. My aim is to improve clarity and objectivity of judgment about what constitutes a fossil angiosperm.

Download or read book The Origin of Higher Taxa written by T.S. Kemp and published by University of Chicago Press. This book was released on 2015-12-16 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the grand sweep of evolution, the origin of radically new kinds of organisms in the fossil record is the result of a relatively simple process: natural selection marching through the ages. Or is it? Does Darwinian evolution acting over a sufficiently long period of time really offer a complete explanation, or are unusual genetic events and particular environmental and ecological circumstances also involved? With The Origin of Higher Taxa, Tom Kemp sifts through the layers of paleobiological, genetic, and ecological evidence on a quest to answer this essential, game-changing question of biology. Looking beyond the microevolutionary force of Darwinian natural selection, Kemp enters the realm of macroevolution, or evolution above the species level. From the origin of mammals to the radiation of flowering plants, these large-scale patterns—such as the rise of novel organismal design, adaptive radiations, and lineage extinctions—encompass the most significant trends and transformations in evolution. As macroevolution cannot be studied by direct observation and experiment, scientists have to rely on the outcome of evolution as evidence for the processes at work, in the form of patterns of species appearances and extinctions in a spotty fossil record, and through the nature of species extant today. Marshalling a wealth of new fossil and molecular evidence and increasingly sophisticated techniques for their study, Kemp here offers a timely and original reinterpretation of how higher taxa such as arthropods, mollusks, mammals, birds, and whales evolved—a bold new take on the history of life.

Book Synopsis Antarctic Paleobiology by : Thomas N. Taylor
Download or read book Antarctic Paleobiology written by Thomas N. Taylor and published by Springer. This book was released on 1990 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.
Book Synopsis Palaeobiology II by : Derek E. G. Briggs
Download or read book Palaeobiology II written by Derek E. G. Briggs and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palaeobiology: A Synthesis was widely acclaimed both for its content and production quality. Ten years on, Derek Briggs and Peter Crowther have once again brought together over 150 leading authorities from around the world to produce Palaeobiology II. Using the same successful formula, the content is arranged as a series of concise articles, taking a thematic approach to the subject, rather than treating the various fossil groups systematically. This entirely new book, with its diversity of new topics and over 100 new contributors, reflects the exciting developments in the field, including accounts of spectacular newly discovered fossils, and embraces data from other disciplines such as astrobiology, geochemistry and genetics. Palaeobiology II will be an invaluable resource, not only for palaeontologists, but also for students and researchers in other branches of the earth and life sciences. Written by an international team of recognised authorities in the field. Content is concise but informative. Demonstrates how palaeobiological studies are at the heart of a range of scientific themes.
