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 using a generation's worth of insights culled 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. First, Ward and Kirschvink argue that catastrophe
shaped life's history more than all other forces combined--from
notorious events like the sudden extinction of dinosaurs to the recently
discovered 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 fabulous and familiar. 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.
