From a renowned biologist and best-selling author, a whole new way of looking at living organisms: reading them as documents describing ancient worlds An exquisitely camouflaged lizard has a desiccated landscape of sand and stones "painted" on its back. Its skin can be read as a description of an ancient desert, a world in which its ancestors survived. Such descriptions are more than skin deep, however. They penetrate the very warp and woof of the entire animal. In this groundbreaking exploration of the power of DNA and what it can reveal about evolution, Richard Dawkins shows how the body, behavior, and genes of every living creature can be read as a book--an archive of the worlds of its ancestors. In the future, a zoologist presented with a hitherto unknown animal will be able to decode its ancestral history, to read its unique "book of the dead." Such readings are already uncovering the remarkable ways in which animals overcome obstacles, adapt to their environments, and, again and again, develop remarkably similar ways of solving life's problems. From the author of The Selfish Gene comes a revolutionary, richly illustrated book that unlocks the door to a past more vivid, nuanced, and fascinating than anything we have seen.
