A journey through the great mass extinction events that have shaped our Earth.This timely and original book lays out the latest scientific understanding of mass extinction on our planet. Cutting-edge techniques across biology, chemistry, physics, and geology have transformed our understanding 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.
