General Interest Extinction: How Life on Earth Nearly Ended 250 Million Years Ago (Princeton Science Library): How Life on Earth Nearly Ended 250 Million Years Ago - Updated Edition: 37 Product DescriptionSome 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.ReviewExtinction is a very enjoyable read. . . . It provides a thoroughly up-to-date account of the causes of the end-Permian event and the developments in the field since 1993 as seen through the eyes of one of the key players. . . .Extinction leaves the reader with the (accurate) picture that here is a scientist whose work has significantly advanced our understanding of the greatest extinction event known to science. . . . A readable and scholarly account.---Richard J. Twitchett, American ScientistDouglas Erwin's geological mystery story is engrossing. It contains a tribute to the scientific method--and also the collaborations of research. The book ends with Erwin warning that the Earth is arguably entering another mass extinction period, this time unnatural and man-made. And this time the destruction may well be total.---Lucy Sussex, The AgeErwin offers a thorough overview of one of the most interesting problems in earth history. . . . Erwin takes the readers on an insider's journey that includes adventures in the field, tedious hours in the laboratory, and stimulating but sometimes contentious exchanges among colleagues at scientific meetings. He gives rigorous consideration to every reasonable hypothesis. . . . Erwin's short course is a professional service for geologists (like me) who have read only some of the primary literature on the end-Permian extinction.---Stephen O. Moshier, Books & CultureFor scientists as well as general educated readers, this book enlightens its readers to the complexity of the largest biological crisis the earth has yet seen.---H.J.M. Meijer, PalArch's Journal of Vertebrate PaleontologyI recommendExtinction: How Life on Earth Nearly Ended 250 Million Years Ago to scientists and nonscientists alike. It provides a clear, comprehensive, and compelling introduction to the greatest catastrophe in the history of animal life and proposes a reasonable hypothesis for the cause of the extinction that will undoubtedly be tested vigorously with new data in the coming decade.---Jonathan L. Payne, ComplexityOne of Choice's Outstanding Academic Titles for 2006Douglas Erwin describes how life on Earth was nearly destroyed at the end of the Permian period, 250 million years ago. . . . The author . . . explains what this paleontological, as well as geological, evidence can tel Shipping Shipping is free for all customers in Australia.
