Stretching from the distant past into the remote future, from primordial Earth to the stars, Evolution is a soaring symphony of struggle, extinction, and survival; a dazzling epic that combines a dozen scientific disciplines and a cast of unforgettable characters to convey the grand drama of evolution in all its awesome majesty and rigorous beauty. Sixty-five million years ago, when dinosaurs ruled the Earth, there lived a small mammal, a proto-primate of the species Purgatorius . From this humble beginning, Baxter traces the human lineage forward through time. The adventure that unfolds is a gripping odyssey governed by chance and competition, a perilous journey to an uncertain destination along a route beset by sudden and catastrophic upheavals. It is a route that ends, for most species, in stagnation or extinction. Why should humanity escape this fate?
