Dalla quarta di copertina
"Douglas Erwin blends careful scholarship and graceful prose in this authoritative elucidation of Earth's greatest mass extinction. Although framed in terms of hypotheses and their tests, Erwin's story unfolds as a gripping who-done-it for the ages."--Andrew H. Knoll, Harvard University, author of Life on a Young Planet
"Douglas Erwin is the world's leading expert on the end-Permian extinction. This book will be the standard reference on this crucial event in the history of life. It is a wonderful example of science in action."--Richard Bambach, Virginia Tech
"This book provides an up-to-date review and critical appraisal of all we know about the end-Permian mass extinction, a subject that has drawn much popular attention. Complementing its solid scholarship, its friendly style enables educated general readers to get to grips with all the current debates."--Paul Wignall, University of Leeds, author of Mass Extinctions and Their Aftermaths
"In conversational prose, Douglas Erwin provides a useful roadmap to a complex scientific subject--an up-to-date treatment of the end-Permian extinction."--Michael J. Foote, University of Chicago
Douglas H. Erwin is senior scientist and curator in the Department of Paleobiology at the Smithsonian's National Museum of Natural History. He began researching the end-Permian mass extinction in the early 1980s and has traveled many times to China, South Africa, and Europe seeking its causes.

That end-Paleozoic transition is named the Permo-Triassic extinction. The name comes from the last period in the Paleozoic (the Permian) and the first period in the Mesozoic (the Triassic). We are talking about an event that happened one quarter of a billion years ago. The task is extremely challenging because the surface of the Earth is remodeled continuously by erosion, mountain building, subduction of ocean sea floor plates, and other geological processes. The author has done a thorough job of providing the reader with an understanding of the tools available to attack the problem. These tools include radioisotope dating techniques, paleontology considerations, the carbon cycle, which can be used to evaluate conditions in the distant past by measuring the relative amounts of C12 and C13. The author liberally gives credit to the many individual scientists each working on a aspect of the bigger problem. He also examines the different hypotheses that have attempted to explain what caused the mass extinction.
Professionals, such as geologists and paleontologists, would be likely to buy this book because they will acquire a powerful reference tool. Moreover, they would make the purchase, knowing in advance, that they can understand the vernicular of the extinction scientist. For others less specialized, the jargon could be an obstacle to understanding the book's contents. Dr. Erwin does attempt to explain the technology to the novice readers and does a good job of it. However, sometimes he forgets that this audience exists and seems to be communicating with his peers alone. The book has photos, charts, graphs and other visual aids which help clarify the textual messages. The extinction was a global event, but there are only a few places on the Earth where evidence still exists. Consequently, the author takes us to China, South Africa, the Rocky Mountains, and other places where he can support his narrative with evidence and examples.
The author presents arguments for the several different hypotheses explaining the great extinction, but does not lock on to any particular one as the best hypothesis. He gives an unbiased voice to each of them, with cautionary comments to the readers about obvious flaws in the reasoning or new evidence which negates previous scientific beliefs. Thus, the book is an unbiased account of what science has been able to learn about the Permo-Triassic extinction. I felt that I learned a lot about mass extinctions in general and this extinction in particular. I know that I should reread it at some future time to better lock in my understanding of the book's contents. Hopefully, you can decide from my review whether or not you would want to learn what this book has to teach you.
Ralph D. Hermansen, November 4, 2013
Erwin names six possible culprits to the extinction:
1) a meteor/comet impact, similar to the one that killed the dinosaurs;
2) climatic changes from massive volcanic flood basalts in Siberia;
3) invasion of invasive species following the creation of the supercontinent Pangea;
4) glaciations causing global cooling and a fall in sea level;
5) disappearance of oxygen from the oceans (anoxia); and
6) a combination of the above.
Because the extinction happened so quickly (estimated less than 160,000 years), he suggests that explanation 3, 4, and 6 are less likely. He also isn't convinced by the evidence of a large meteor impact (1) around this time. Furthermore, explanation 5 does not account for the extinctions on land. Thus, the book tentatively concludes that the volcanic flood basalts seem to have played the largest role in the extinction, perhaps by causing runaway global warming.
This is a science book, not a book about the scientists. Too many popular books about paleontology, especially those written by journalists, seem to focus on the scientists themselves rather than the actual science. Fortunately, Erwin goes deep into the scientific evidence and presents detailed arguments for each explanation.
Perhaps more important than the hard scientific evidence (which may well become outdated by the time you read the book, if it hasn't already), Erwin does a magnificent job showing the process and reasoning that goes into collecting and interpreting the evidence. Rather than state his interpretation of the evidence, Erwin takes the reader through the existing evidence and the questions or concerns he has with it. Most of the book consists of his summary of paleobiologists' toolkit and the research on the Permian extinction. He only brings the evidence together to discuss the potential culprits in the last few chapters. However, by writing the book this way, the reader is able to assess the evidence for himself.
Erwin's style also encourages readers to keep a healthy sense of doubt, especially since more than once he admits his past positions on the extinction were probably wrong. In fact, he does suggest that more evidence regarding a meteor impact has recently emerged and may contradict his "preferred" theory.
Overall this is a very interesting book, but is a long read, especially for those readers who - like me - have no formal training in paleontology or geology. However, the books provides a great science education for those willing to put in the time.
I also appreciate the author's introspective style; he doesn't have all the answers, nor does he pretend to. Credit is given to fellow geologists for their field and lab work, and overall the reader gets a good sense of life (and death) on this planet 250 million years ago.
If I were a paleontologist, no doubt this would be a 5 star read. As is, it's an excellent overview of a very intriguing period of time in our planet's history that anyone can enjoy, regardless of their level of knowledge for the subject at hand.
I am keeping this book nearby as I plan to re-read it in the near future; I found it that engaging.
