I just picked up The Genetic Book of the Dead: A Darwinian Reverie by Richard Dawkins. The book is filled with fascinating examples of the power of Darwinian natural selection to build exquisite perfection, paradoxically accompanied by what look like gross blunders. Along the way, Dawkins dismantles influential criticisms of the 'gene's-eye-view' of life. And, to end with a provocative sting in the tail, the author asks there is a sense in which all our 'own' genes can be seen as a gigantic colony of cooperating viruses?
