Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary origin and early history of the angiosperms (or flowering plants), which are the dominant land plants today, has remained an unsolved problem since the time of Darwin. It has been referred to since those days as an 'abominable mystery', because neither direct ancestor nor an agreed date could be determined. Mr Hughes argues that previous approaches, mostly through botanical theory, have been inadequate and misleading. He suggests that the date is about 110 million years ago (in the Cretaceous period) and there is a good chance of ancestors being found if the correct approach is adopted to the study of other fossil plants of that period. Moreover, the study of plant microfossils in the past twenty years has made feasible a fuller geological study of other fossils. When this book was first published in 1976, several reviewers saw it as a timely book on a controversial subject.

Download or read book The Origins of Angiosperms and their Biological Consequences written by Else Marie Friis and published by Cambridge University Press. This book was released on 1989-05-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published in 1989. The dramatic radiation of the angiosperms towards the end of the Early Cretaceous initiated major changes in terrestrial ecosystems throughout the world. Dramatic changes in the flora and fauna were exemplified by the development of angiosperm-dominated plant communities and the rapid diversification of mammals, birds and insects. Written specifically for use by advanced undergraduate and graduate students, the book presents an overview of works on the origins of angiosperms and the ecological effects upon terrestrial life of their rapid radiation. It will be of particular value to students of palaeobiology and ecology, as well as to those studying evolutionary biology and systematics.

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.
Download or read book The Dawn Angiosperms written by Xin Wang and published by Springer. This book was released on 2011-07-23 with total page 238 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This text discusses whether the origin of radically new kinds of organisms - new higher taxa - are the result of normal Darwinian evolution proceeding, or whether unusual genetic processes and/or special environmental circumstances are necessary.
Download or read book Early Flowers and Angiosperm Evolution written by Else Marie Friis and published by Cambridge University Press. This book was released on 2011-08-18 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.

This book was released on 2013-04-25 with total page 1001 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of the science of the history of life. Paleobiologists bring many analytical tools to bear in interpreting the fossil record and the book introduces the latest techniques, from multivariate investigations of biogeography and biostratigraphy to engineering analysis of dinosaur skulls, and from homeobox genes to cladistics. All the well-known fossil groups are included, including microfossils and invertebrates, but an important feature is the thorough coverage of plants, vertebrates and trace fossils together with discussion of the origins of both life and the metazoans. All key related subjects are introduced, such as systematics, ecology, evolution and development, stratigraphy and their roles in understanding where life came from and how it evolved and diversified. Unique features of the book are the numerous case studies from current research that lead students to the primary literature, analytical and mathematical explanations and tools, together with associated problem sets and practical schedules for instructors and students. “..any serious student of geology who does not pick this book off the shelf will be putting themselves at a huge disadvantage. The material may be complex, but the text is extremely accessible and well organized, and the book ought to be essential reading for palaeontologists at undergraduate, postgraduate and more advanced levels—both in Britain as well as in North America.” Falcon-Lang, H., Proc. Geol. Assoc. 2010 “...this is an excellent introduction to palaeontology in general. It is well structured, accessibly written and pleasantly informative .....I would recommend this as a standard reference text to all my students without hesitation.” David Norman Geol Mag 2010 Companion website This book includes a companion website at: www.blackwellpublishing.com/paleobiology The website includes: · An ongoing database of additional Practical’s prepared by the authors · Figures from the text for downloading · Useful links for each chapter · Updates from the authors

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, T.S. 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. -- from back cover.
