A New History of Life ─ The Radical New Discoveries About the Origins and Evolution of Life on Earth

Charles Darwin's theories, first published more than 150 years ago, still set the paradigm of how we understand the evolution of life--but scientific advances of recent decades have radically altered that. Now two pioneering scientists draw on their years of experience in paleontology, biology, chemistry, and astrobiology to deliver an eye-opening narrative that synthesizes a generation's worth of insights from new research.

Writing with zest, humor, and clarity, Ward and Kirschvink show that many of our long-held beliefs about the history of life are wrong. Three central themes emerge from the narrative. First, catastrophe, argue Ward and Kirschvink, shaped life's history more than all other forces combined--from notorious events like the sudden extinction of dinosaurs to recently discovered ones like "Snowball Earth" and the "Great Oxygenation Event." Second, life consists of carbon, but oxygen, carbon dioxide, and hydrogen sulfide determined how it evolved. Third, ever since Darwin we have thought of evolution in terms of species. Yet it is the evolution of ecosystems--from deep-ocean vents to rainforests--that has formed the living world as we know it. Ward and Kirschvink tell a story of life on Earth that is at once too fabulous to imagine and too familiar to dismiss. And in a provocative coda, they assemble discoveries from the latest cutting-edge research to imagine how the history of life might unfold deep into the future.

Peter Ward is a Professor of Biology and Professor of Earth and Space Sciences at the University of Washington. He has authored seventeen books, among them the prizewinning Rare Earth: Why Complex Life Is Uncommon in the Universe, with Donald Brownlee. He has been a main speaker at TED and has received the Jim Shea Award for popular science writing. He lives in Washington.Joe Kirschvink is the Nico and Marilyn Van Wingen Professor of Geobiology at the California Institute of Technology, as well as a Fellow of the American Society for the Advancement of Science and the American Academy of Arts and Sciences. His pioneering work in earth science includes formulating and naming the "Snowball Earth" hypothesis. He lives in Pasadena, California.
