Download or read book Origin by Design written by Harold G. Coffin and published by Review and Herald Pub Assoc. This book was released on 2005 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: In search of evidence for design, the authors leave no stone unturned. After surveying the Genesis creation and flood narratives, they examine coal beds, fossil tracks, mass extinctions, glaciation, volcanism, carbon 14 dating, rates of mutation, and Neanderthal man, looking for clues to the age and origin of life on earth. With copius illustrations this updated revision incorporates new advances in plate tectonics, turbidity currents, and recent geological catastrophes. A wonderful science-based textbook and reference for the question of our beginnings.
Download or read book Phylogeny and Evolution of the Angiosperms written by Douglas Soltis and published by University of Chicago Press. This book was released on 2018-01-24 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Download or read book From Greenhouse to Icehouse written by Donald R. Prothero and published by Columbia University Press. This book was released on 2003 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marine Eocene-Oligocene transition of 34 million years ago was a critical turning point in Earth's climatic history, when the warm, high-diversity "greenhouse" world of the early Eocene ceded to the glacial, "icehouse" conditions of the early Oligocene. This book surveys the advances in stratigraphic and paleontological research and isotopic analysis made since 1989 in regard to marine deposits around the world. In particular, it summarizes the high-resolution details of the so-called doubthouse interval (roughly 45 to 34 million years ago), which is critical to testing climatic and evolutionary hypotheses about the Eocene deterioration. The authors' goals are to discuss the latest information concerning climatic and oceanographic change associated with this transition and to examine geographic and taxonomic patterns in biotic turnover that provide clues about where, when, and how fast these environmental changes happened. They address a range of topics, including the tectonic and paleogeographic setting of the Paleogene; specific issues related to the stratigraphy of shelf deposits; advances in recognizing and correlating boundary sections; trends in the expression of climate change; and patterns of faunal and floral turnover. In the process, they produce a valuable synthesis of patterns of change by latitude and environment.

Download or read book Soil Grown Tall written by Gregory J. Retallack and published by Springer Nature. This book was released on 2022-02-16 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed as an easy night's read and introduction to fossil soils and the relatively new disciplines of Paleopedology and Astropedology. It includes line art and color illustrations to visualize the topic for the informed layperson or interested colleagues. It provides comprehensive information on paleosols, which are soils of the past providing a variety of clues to the evolution of life and climate on Earth and deals with topics such as the evolution of grassland ecosystems, mass extinction of the Late Permian and origin of life, all viewed from the perspective of the fossil record of soils. This turns out to be a refreshing new perspective of wide interest.
Download or read book Volcanoes to Vineyards written by Jim E. O'Connor and published by Geological Society of America. This book was released on 2009 with total page 886 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume contains guides for 34 geological field trips offered in conjunction with the October 2009 GSA Annual Meeting in Portland, Oregon. Showcasing the region's geological diversity, the peer-reviewed papers included here span topics ranging from accreted terrains and mantle plumes to volcanoes, floods, and vineyard terroir. Locations visited throughout Oregon, Washington, and Idaho encompass Astoria to Zillah. More than just a series of maps, the accompanying descriptions, observations, and conclusions offer new insights to the geologic processes and history of the Pacific Northwest - insights that will inspire readers to put their boots on the evidence as they develop their own understanding of this remarkable and dynamic corner of the world."--Publisher's description.
