The Yellow-Lighted Bookshop

Richard Dawkins shows how the body, behaviour, and genes of every living creature can be read as a book – an archive of the worlds of its ancestors. A perfectly camouflaged desert lizard has a desiccated landscape of sand and stones ‘painted’ on its back. Its skin can be read as a description of ancient deserts in which its ancestors survived – and, before that, of the worlds of its more remote ancestors: a genetic book of the dead. But such descriptions are more than skin-deep. The fine chisels of Darwinian natural selection carve their way through the very warp and woof of the body, into every biochemical nook and corner, into every cell of every living creature. A zoologist of the future, presented with a hitherto-unknown animal, will be able to reconstruct the worlds that shaped its ancestors, to read its unique ‘book of the dead’.
