Some 250 million years ago, the Earth suffered the greatest biological crisis in its history. Extinction is a paleontological mystery story that 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 - and set the stage for the development of life as we know it today.

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.
