If we"re so smart, why are we still at the mercy of treacherous microorganisms? The Genius Within: Discovering the Intelligence of Every Living Thing asks readers to let go of brain worship and look at the incredible problem-solving skills of viruses, ants, and other lowly creatures. Neurosurgeon Frank T. Vertosick Jr. seems an unlikely candidate to write a book celebrating noncerebral intelligence, but his knowledge helps him draw comparisons that others might miss. The fast-moving genetic intelligence of bacteria and immune systems might not match the precision of digital computers, but they have devised arms races much more complex--and deadly--than our comparatively paltry efforts. Vertosick"s grasp of what it means to behave intelligently comes through clearly, even if he is as stumped as anyone trying to define the I word. Exploring parallels between neural networks, insect colonies, and our own brains, he finds common ground and shows that, as far as evolution is concerned, we"re not so bright. It"s not all bad, though: we"re very good at what we do, and Vertosick hopes that we can learn to use our intelligence more wisely. --Rob Lightner
