Book excerpt: The history of life on Earth is punctuated by half a dozen puzzling mass extinctions that constitute the benchmarks of the geologic time scale. These great breaks in the continuity of the fossil record have invited a wide array of scientific speculation. The most thoroughly studied of the mass extinctions occurred 65 million years ago when most life on Earth, incl. the dinosaurs, perished. Two rival hypotheses have emerged to account for this catastrophic event: the "impactor" hypothesis sees the earth bombarded with deadly meteorites, while the competing "volcanist" hypothesis evokes gigantic volcanic eruptions. This book examines the arguments and behavior of the scientists who have been locked in conflict over the competing hypotheses.

Available in PDF, EPUB and Kindle. Book excerpt: ONE OF THE NEW YORK TIMES BOOK REVIEW'S 10 BEST BOOKS OF THE YEAR A major book about the future of the world, blending intellectual and natural history and field reporting into a powerful account of the mass extinction unfolding before our eyes Over the last half a billion years, there have been five mass extinctions, when the diversity of life on earth suddenly and dramatically contracted. Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In The Sixth Extinction, two-time winner of the National Magazine Award and New Yorker writer Elizabeth Kolbert draws on the work of scores of researchers in half a dozen disciplines, accompanying many of them into the field: geologists who study deep ocean cores, botanists who follow the tree line as it climbs up the Andes, marine biologists who dive off the Great Barrier Reef. She introduces us to a dozen species, some already gone, others facing extinction, including the Panamian golden frog, staghorn coral, the great auk, and the Sumatran rhino. Through these stories, Kolbert provides a moving account of the disappearances occurring all around us and traces the evolution of extinction as concept, from its first articulation by Georges Cuvier in revolutionary Paris up through the present day. The sixth extinction is likely to be mankind's most lasting legacy; as Kolbert observes, it compels us to rethink the fundamental question of what it means to be human.

Download or read book Extinction written by Douglas H. Erwin and published by Princeton University Press. This book was released on 2015-03-22 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.
Book Synopsis The Great Dinosaur Extinction Controversy by : Charles Officer
Download or read book The Great Dinosaur Extinction Controversy written by Charles Officer and published by Addison Wesley Publishing Company. This book was released on 1996-06-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.

Book Synopsis Imagining Extinction by : Ursula K. Heise
Download or read book Imagining Extinction written by Ursula K. Heise and published by University of Chicago Press. This book was released on 2016-08-10 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the extinction of species accelerates and more species become endangered, activists, filmmakers, writers, and artists have responded to bring this global crisis to the attention of the public. Until now, there has been no study of the frameworks that shape these narratives and images, or of the symbolic meanings that the death of species carries in different cultural communities. Ursula Heise makes the case that understanding how and why endangered species come to matter culturally is indispensable for any effective advocacy on their behalf. Heise begins by showing that the tools of conservation science and law need to be viewed as cultural artifacts: biodiversity databases and laws for the protection of threatened species use rhetorical and cultural resources that open up different approaches to the problem of understanding global wildlife. The second half of her book explores ways of envisioning alternative futures for biodiversity. The narrative of nature s decline or even imminent disappearance has been a successful rallying trope for those skeptical of modernization and ideologies of progress. But environmentalists nostalgia for the past and pessimistic outlook on the future have also alienated parts of the public. Heise tells the story of environmental activists, writers, and scientists who are creating new stories to guide the environmental imagination."
Book Synopsis The Great Dinosaur Controversy by : Keith Parsons
Download or read book The Great Dinosaur Controversy written by Keith Parsons and published by Bloomsbury Publishing USA. This book was released on 2003-12-02 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: A historical review of the most important scientific controversies that have shaped our knowledge of dinosaurs since the discovery of important fossils in the 1820s. In The Great Dinosaur Controversy: A Guide to the Debates, the major scientific disputes that have contributed to the understanding of dinosaurs come to light. Each chapter presents a major controversy then ponders the lessons learned and their impact on the scientific field. Colorful characters such as "anti-evolutionist" Robert Owen, "Darwin's bulldog," T.H. Huxley, and "dinosaur heretic" Robert Bakker, enliven the debates, which range from the origin of dinosaurs and their posture to their evolution or retrogression and whether they were warm- or cold-blooded. Two of the most recent debates concern how dinosaurs became extinct and whether or not birds are their descendents.

Book Synopsis Sparing Nature by : Jeffrey Kevin McKee
Download or read book Sparing Nature written by Jeffrey Kevin McKee and published by Rutgers University Press. This book was released on 2003 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text asserts that a stroke should be thought of as a syndrome, or collection of disease processes, rather than a single disease. Strokes are characterized by restriction of blood flow to the brain and are responsible for imposing a very significant burden on healthcare systems, accounting for more than four million deaths per year. They can be directly linked to the majority of adult neurological disability and they contribute to vascular dementia, the second most common cause of dementia after Alzheimer's Disease. Despite its importance on a population basis, research into the genetics of strokes has lagged behind many other disorders; however, the situation is changing and there is now growing evidence that genetic factors are important in the stroke risk, often acting via interactions with conventional risk factors.

Book Synopsis Carboniferous Giants and Mass Extinction by : George R. McGhee Jr.
Download or read book Carboniferous Giants and Mass Extinction written by George R. McGhee Jr. and published by Columbia University Press. This book was released on 2018-08-07 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: Picture a world of dog-sized scorpions and millipedes as long as a car; tropical rainforests with trees towering over 150 feet into the sky and a giant polar continent five times larger than Antarctica. That world was not imaginary; it was the earth more than 300 million years ago in the Carboniferous period of the Paleozoic era. In Carboniferous Giants and Mass Extinction, George R. McGhee Jr. explores that ancient world, explaining its origins; its downfall in the end-Permian mass extinction, the greatest biodiversity crisis to occur since the evolution of animal life on Earth; and how its legacies still affect us today. McGhee investigates the consequences of the Late Paleozoic ice age in this comprehensive portrait of the effects of ancient climate change on global ecology. Carboniferous Giants and Mass Extinction examines the climatic conditions that allowed for the evolution of gigantic animals and the formation of the largest tropical rainforests ever to exist, which in time turned into the coal that made the industrial revolution possible—and fuels the engine of contemporary anthropogenic climate change. Exploring the strange and fascinating flora and fauna of the Late Paleozoic ice age world, McGhee focuses his analysis on the forces that brought this world to an abrupt and violent end. Synthesizing decades of research and new discoveries, this comprehensive book provides a wealth of insights into past and present extinction events and climate change.
