Extinctions Av Michael J. Benton

A journey through the great mass-extinction events that have shaped our Earth. In this vast sweep of our Earth¿s history, Michael Benton brings the deep past to life as never before. Deploying the cutting-edge tools in biology, chemistry, physics and geology that are transforming our understanding of previous environmental cataclysms ¿ including the incredible new discovery of a hitherto unknown extinction event ¿ he uncovers not only their lethal effects but also the processes that brought about such large-scale destruction. Beginning with the oldest extinction, Benton investigates the Late Ordovician, which set the evolution of the first animals on an entirely new course; the late Devonian, brought on by global warming; the cataclysmic End-Permian, which wiped out over 90 per cent of all life on Earth; and, book-ending the age of the dinosaurs, the newly discovered Carnian Pluvial Event and the End-Cretaceous asteroid. He examines how global warming, acid rain, ocean acidification, e

A journey through the great mass-extinction events that have shaped our Earth. Drawing on the latest research, this timely and original book lays out the current scientific understanding of mass extinction on our planet. Cutting-edge techniques across biology, chemistry, physics and geology have transformed our knowledge of the deep past, including the discovery of a previously unknown mass extinction.This compelling evidence, revealing a series of environmental crises resulting in the near-collapse of life on Earth, illuminates our current dilemmas in exquisite detail. Beginning with the oldest, Professor Michael J. Benton takes us through the 'big five' die-outs: the Late Ordovician, which set the evolution of the first animals on an entirely new course; the late Devonian, apparently brought on by global warming; the cataclysmic End-Permian, also known as the Great Dying, which wiped out over 90% of all life on Earth; and, book-ending the age of the dinosaurs, the newly discovered Carnian Pluvial Event and the End-Cretaceous asteroid.He examines how global warming, acid rain, ocean acidification, erupting volcanoes and meteorite impact have affected conditions on Earth, the drastic consequences for global ecology, and how life in turn survived, adapted and evolved. Benton's expert retelling of the scientific breakthroughs are illustrated throughout with photographs of fossils and fieldwork, scenes from the laboratory and artistic reconstructions of ancient environments that bring us face to face with long-lost life forms. We learn how scientists have developed revolutionary new tools to uncover ancient extinction events and processes in forensic detail, how they model evolving systems, and how they are honing their methods to improve our understanding of the deep past.New research allows us to link long-ago upheavals to crises in our current age, the Anthropocene, with important consequences for us all.
