Review

"One of Choice's Outstanding Academic Titles for 2006""Theories and mysteries can be dispelled with good data from the geologic record, and Erwin (a paleobiologist at the Smithsonian Institution's National Museum of Natural History) offers an authoritative account of the search for these data and for the cause of the extinction. . . . Extinction provides a great reference for researchers and the interested lay reader alike."---Andrew M. Bush, Science"Extinction 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 Scientist"Douglas 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 Age"Douglas H. Erwin, a Smithsonian paleobiologist and one of the leading experts on the Permian extinction has meticulously sifted through the evidence. . . . His accessible new book, Extinction--written, it seems, both to persuade his colleagues and to educate a lay audience--is told from the perspective of a forensic scientist trying to piece together a quarter-billion-year-old crime scene."---Joshua Foer, Washington Post Book World"Douglas Erwin describes how life on Earth was nearly destroyed at the end of the Permian period, 250 million years ago. . . . The author . . . explain[s] what this paleontological, as well as geological, evidence can tell scientists about the dramatic and deadly shift in the Earth's environment." (Science News)"No one can tell this story better than Douglas Erwin. His book is a superbly written account of what we know about the Permian extinctions. . . . More than a geological story, this book is an excellent model of how science addresses complicated questions." (Choice)"This book does not justify a single, accepted causal sequence of events . . . to account for the end-Permian extinction. Instead, Erwin dissects the evidence for and against each hypothesis, impartially weighing their strengths and weaknesses. Although this book may frustrate readers expecting to learn how life nearly ended 250 million years ago, it will reward them with a fascinating case study in scientific inference, a case that remains very much open."---John P. Hunter, Quarterly Review of Biology"Erwin's book is science writing for the general public at its best and most lucid. Entertaining, informative, and thought provoking." (Northeastern Naturalist)"Erwin 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 & Culture

The title of the book is "Extinction: How Life on Earth Nearly Ended 250 Million Years Ago" and the author is Douglas H. Erwin. Our planet has a sometimes very violent history, which is recorded in its rock strata. How do we decipher it? Geology is one major discipline with the tools, whereas paleontology is another. Strata record a chronology of the Earth based on the premise that older strata lie beneath younger strata. Scientists have compared strata from around the world and matched up similar time periods (i.e.; identical strata). Multi-cell plants and animals have left their fossils in the last half billion years of the Earth's history. Three major divisions (eras) became evident to scientists: the Paleozoic Era, the Mesozoic Era, and the Cenozoic Era. The first era contains the story of primitive multi-cell animals, first fishes, first amphibians, and first reptiles. Then the mother of all global extinctions occurred and wiped out 95% of all species. The next era (Mesozoic) was the age of the dinosaurs and it lasted well over 120 million years. Again, a global extinction wiped out the dinosaurs and several other species. Since that mass extinction event 65 million years ago, new kinds of animals have repopulated the Earth, namely mammals and birds. This book focuses on that major extinction at the end of the Paleozoic and teaches what science can deduce about it.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

This book reads like a murder mystery, with the victim being 95% of all marine life and 70% of terrestrial vertebrates species. This crime, the Permian Extinction, occurred over 250 million years ago but still has not been solved. The author Douglas Erwin, a paleobiologist who has been working on the extinction for the past few decades, identifies identifies possible culprits and the known evidence, but ultimately comes to no conclusion. This makes the book both exciting and fresh (even three years after its initial publication).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); and6) 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.

The author does a fine job explaining the possible causation of the Permo-Triassic extinction. He keeps the necessary technical babble to a minimum, making this book (mostly) accessible to any lay person. Some of the charts were confusing to me, but I got the gist of things. The chapters are well organized, and his method of making the book a "geological mystery" is very well executed.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.
