For over a century scientists have tried to identify and understand the processes responsible for the complex history of species extinction. This search has become even more important over the last decade as human populations and human technology may now rival sea-level change, volcanic eruptions, and asteroid impacts as extinction mechanisms. The Great Extinctions explores the history of that search, its subjects, its controversies, its current conclusions, and the meaning of those conclusions for our efforts to preserve the Earth's current biodiversity. Life's rich tapestry has escalated over time, despite several major setbacks. In total some 1,000-3,000 million species are estimated to have appeared during Earth's history, yet only 12.5 million currently exist today. This means that the overwhelming majority of species that have ever lived are now extinct. In The Great Extinctions leading palaeontologist Norman MacLeod reveals how, contrary to popular conception, species extinction is as natural a process as species evolution. Examining extinction over geological time, he compares ancient extinction events and uses them to predict what might happen in the future. Featuring the latest evidence on the subject and informative illustrations and diagrams throughout, The Great Extinctions is a comprehensive guide to extinctions, their causes and their effects on evolutionary processes.
Professor Norman MacLeod is Dean of Postgraduate Studies and Training at the Natural History Museum, London. His research involves studies of extinction, the origin and evolution of form in fossils and modern organisms, and the distribution of ancient and modern species in time. He is the author of numerous books, technical reports and review articles on the subject of extinction.

For more than a century scientists have tried to identify and understand the precise processes responsible for species extinction. Solving the species extinction puzzle has become even more important, even urgent, as human populations and technologies rival sea-level change, volcanic eruptions and asteroid impacts as an extinction mechanism. The Great Extinctions explores the search for an understanding of Earth's five great extinction events and whether the sixth is upon us already. Leading paleontologist Norman MacLeod examines the controversies and conclusions and what they mean to the efforts to preserve Earth's biodiversity. He also reveals how, contrary to popular conception, species extinction is as natural a process as species evolution. Examining extinction over geological time, he compares ancient extinction events and uses them to predict future extinctions. Featuring the latest scientific evidence on the subject and informative illustrations and diagrams, The Great Extinctions is an easy-to-understand presentation of a complex and controversial subject.
