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. New research allows us to link long-ago upheavals to crises in our current age, the Anthropocene, with important consequences for us all.
