Just 12,000 years ago - at the height of the last Ice Age - saber-toothed tigers, giant ground sloths, camels, hippos and the great herds of proboscideans: giant mastodons and mammoths, extinct relatives of the elephant, roamed the land where skyscrapers now stand. Why are these splendid creatures no longer with us? This compelling book explores the reasons for these extinctions and provides a tour of mass extinctions throughout earth's history, including the great comet crash that killed off the dinosaurs. Brilliantly written, is an engaging exploration of the history of life and the importance of humanity as an evolutionary force.weiterlesen
