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.

Hardback. Etat : Good. A fascinating history of species extinctions, their causes and the looming sixth extinction. It is the central issue for this generation. Respected journals and popular publications worldwide pose the question, call the warning: Are we in the middle of a sixth mass extinction? (Science), Multitude of species face climate threat (The New York Times), The sixth great extinction: a silent extermination (National Geographic). Of the 1-3 billion species estimated to have appeared during Earth's history, only 12.5 million exist today. Geologists know that species extinction is as natural a process as species evolution. They also know that the rate of extinction in the geological past has not been constant. On at least five occasions in Earth's history, extinction intensities have spiked well above the normal level. For over a century, geologists have tried to conclusively identify and understand the processes responsible for the complex, fluctuating history of species extinction through the millennia. This has become even more important over the last decade as human populations and technology may now rival sea-level change, volcanic eruptions and asteroid impacts as an extinction mechanism. Will there be a sixth Extinction? When? What will cause it? The Great Extinctions explores the history of this search, its subjects, its controversies, its current conclusions, and their implications for our efforts to preserve Earth's biodiversity. It explains what extinction is, what causes it and whether it is preventable, and by comparing past geological extinction events, it aims to predict what will happen in the future. Author Norman MacLeod covers this compelling topic in a concise, easy-to-read style with illustrations and diagrams throughout. He examines a controversial subject with universal implications, which will fascinate a wide readership with interests in geology, prehistory, the environment, endangered species, conservation, wildlife, biodiversity, climate change, zoology, botany, invasive species and more. The Great Extinctions is an essential choice for an informed contemporary readership. N° de réf. du vendeur 00105255976
