Without it, we'd all be lobsters Simon Ings, a science writer and novelist, wrote The Eye to order, so to speak - his agent had been looking for someone to write a popular book on the subject. If that sounds an unpromising start, the end product belies its conception. Ings has succeeded in writing an elegant, entertaining and up-to-date overview of cutting-edge research. He tells the story "episodically", in a "mix of history, science and anecdote" that is utterly compelling. What links the exquisite diversity of ways of seeing throughout the living world is a shared drive to harness light, he argues. "Animals did perfectly well without eyes" for 200 million years. "They ate algae. They slumped. They pulsed. But then there were eyes - and the fun began." Wasps won't sting if you stay still. Ings tells you why; their coarse-grained vision enables them to map food sources on the wing - but move and they panic. "To say this puts the wasp at a disadvantage is putting it mildly: why else do you think it evolved a sting?" The insect's compound eye, with its rough, pixellated view of the world, is a disastrous design. Some 20 million years ago, spiders and scorpions managed to abandon complex eyes in favour of single-chamber ones more like our own, with much better results. Today's true spiders have eight eyes - with the best, high-resolution ones as powerful as those of small rodents. The arrival of eyed vertebrates introduced a profound optical innovation - flexible, transparent lenses built out of stable proteins. The breakthrough meant that animals could become much bigger, because they were able to spot smaller prey, and larger predators, a long way away. "Had it not been for the vertebrate eye, living things would probably have remained lobster-sized for ever." Humans, equipped with a fovea in the centre of the retina, enjoy a visual acuity that rivals birds of prey. Why are we virtually eagle-eyed? All the better to watch each other, is one answer Ings entertainingly explores. Humans, exceptionally, have bright "whites" to their eyes - "precisely so that an individual can tell where its fellows are looking". Ings tackles colour vision, robotic vision, weapons that blind or daze, and a dazzling array of visual illusions. Humans see only two degrees of the world with any clarity, and are simply blind to most of what is going on. The planet's dominant species is "an animal who sees only what it wants to see".
