在無止盡的演化過程當中，大自然扮演著主持人的角色。自從有生命以來將近99.9%的生物都已滅絕。為了生存下去，包含人類在內的所有生物都得精通自己與生俱來的武器並在生命這個戰場上奮力求生。這些驚人的武器包括了像是暴龍13英寸的犬齒、壁虎有如魔術貼般的腳蹼、禿鷹那有如望遠鏡般的視力能發現一英里外的野兔。這些演化到底由何而來？它們並不是憑空出現，一切的一切都是為了讓這些動物們能擁有在這場戰爭中獨樹一格的武器，唯有進化才能繼續生存。
Throughout eons of evolution, the natural world has played host to this never-ending competition. Since the dawn of time roughly ninety-nine percent of all species have become extinct. In order to survive, all creatures, including man, must treat life as a battlefield and master the natural weapons and defenses that have evolved: Tyrannosaurus Rex's 13-inch canines; the gecko's Velcro-like toe pads; the bald eagle's telescopic vision that is capable of spotting a hare a mile away. What is the history of these evolutions and how did they come about? They didn't just appear arbitrarily, they evolved for a common reason - to give these animals a critical edge in interspecies warfare. To evolve is to conquer!
