"[Alvarez] revels in the unlikely reality of life on Earth...enabling readers to experience the power of Big History." -- Science "Fans of Bill Bryson's A Short History of Nearly Everything will appreciate Alvarez's enthusiastic, clearly written tour of contingencies that have shaped our world, starting with the origins of life on Earth." -- Science News "For the past three decades, Walter Alvarez has been at the center of a revolution in how scientists think about the history of life and the Earth. In A Most Improbable Journey he gives us the biggest history of all, going from the Big Bang to our own place on the planet. Lively and profound and flavored with his infectious enthusiasm, Alvarez shows how each of us has won a truly massive lottery just to be a sentient being on this planet." -- Neil Shubin, best-selling author of Your Inner Fish "A wonderful account of Big History by a geologist. And not just any geologist, but the geologist who showed that the dinosaurs were done in by an unlucky asteroid strike! Alvarez writes with precision and great charm. And he reminds us how absurdly improbable is the role we play in this colossal story, and how many things had to go right for you and me to exist." -- David Christian, founder of the field of Big History and author of Maps of Time "Engaging." -- Nature
