"Andrew Knoll, one of the world's foremost paleontologists, here presents the origin and early evolution of life the way it should be told: a mystery unfolding as an epic. Resonating with the authority of firsthand stories of discovery, his account will be exceptionally enjoyable for scientists and the educated public alike."--Edward O. Wilson, Harvard University

"Here is a firsthand account of one of the most exciting quests in modern science. Knoll writes with the confidence of a distinguished scientist who has devoted his career to unraveling the mysteries of life's origins and the passion of someone who deeply believes in the importance of recent discoveries about life before the Cambrian explosion. From the wilds of Siberia to the ocean floor, from Earth to Mars and beyond, he takes readers on a fascinating personal adventure that may change the way they think about themselves and their place in the world."--Lawrence M. Krauss, author of The Physics of Star Trek and Atom

"In a highly personal, gripping narrative, Knoll takes us on the most incredible journey of all journeys--the history of life on Earth."--Donald E. Canfield, Odense University

"This is a truly great book. It is a remarkably readable synthesis of many diverse ideas selected from a breathtaking array of disciplines. The narrative is engaging and entertaining--a travelogue through time that incorporates amusing and informative anecdotes from Knoll's travels to many far-off places."--Sean Carroll, University of Wisconsin, author of From DNA to Diversity
