5.0 out of 5 stars
highly readable and informative book on extinction, March 2, 2001
This review is from: Extinction: Bad Genes or Bad Luck? (Paperback)
David M. Raup does an extraordinary job in this fine work on the mysteries of extinction. Addressing not only the infamous K-T extinction event that wiped out the dinosaurs, pterosaurs, prehistoric marine reptiles, ammonites, and many less well known organims of the Mesozoic, he addresses other significant extinction events in earth's history, ranging from the Cambrian period all the way up to extinctions in recent centuries, such as the heath hen in the eastern United States. Raup is able to draw many interesting theories and conclusions by analyzing extinction as an event and process seperate from and beyond the details of the individual organisms. Too many works, at least popular works, dwell overmuch on the extinction of the dinosaurs and related archosaur fauna (and to a lesser extent the mammalian and avian megafauna at the end of the Pleistocene)and fail to draw overall conclusions about what extinction is, how it comes about, and what roles it plays in the history of life on earth. Though the details of particular organims that become extinct are important, Raup seeks to draw broader and more widely applicable conclusions, and in this he succeeds brilliantly.
Raup analyzes and addresses a variety of potential causes of extinction from biological (such as predation, epidemic disease, etc.) to physical (sea level rises and falls, volcanism, etc.) to fairly exotic (cosmic radiation, asteroid impact, etc.), as well of course interactions between various causes. He also discusses the importance of small population sizes playing a role in and of themselves in a species extinction, how small populations (using the heath hen as an example) are uniquely vulnerable to such factors as demographic stochasticity, extrinsic forces, social dysfunction, and so forth, all described in informative but very readable format. The debate over the role of small population size is particularly interesting in discussions of potential modern day extinctions, a probelm faced by modern day conservationists and environmentalists.
Weaving in discussions of probability, statistics, geology, astronomy, climate, and the overall history of life on earth, Raup does an excellent job on the subject of extinction. Any amateur paleontologist or indeed biologist, as well as those involved in conservation efforts, would be well served by this book.

A good question..., May 14, 1999
This review is from: Extinction: Bad Genes or Bad Luck? (Paperback)
Raup does a great job outlining many of the leading ideas regarding extinction theory. Ideas in the book are presented with examples that are easy to follow, and Raup points out possibilities without overburdening the reader with a heavy-handed dose of bias, leaving readers to make up their own minds about things. I particularly appreciated the range of ideas covered by the author regarding current thought about extinction. The book seemed a bit light for a scientific audience, but it is pitched well for the lay naturalist reader. I'm glad I read it.

Extinction, April 24, 2000
This review is from: Extinction: Bad Genes or Bad Luck? (Paperback)
This is a delightfully well written book on the phenomenon of extinction, from the background rates of species death to the massive die-offs of the KT and other major extinction events. The author approaches the subject from a statistical/probabilities standpoint, looking at extinction as a continuum which is characterised, as he notes, by "long periods of boredom interrupted occasionally by panic." He introduces the concept of Gambler's Ruin, which makes his thesis understandable even to the statistically challenged like myself. The sense of humor with which he injects his work makes a complex subject entirely enjoyable.
