IN THE IMMORTAL WORDS of T.S. Eliot: "Oh, do not ask, 'What is it?' / Let us go and make our visit." Do not ask, for On the Origin of Tepees is not your usual sort of book. Jonnie Hughes, a British TV and radio science guy, is like a carnival barker on serious weed. He is like Carl Sagan without segues, Jacques Cousteau without the hat, Mutual of Omaha's Wild Kingdom without the kingdom ... Wait, wait, I've got it: On the Origin of Tepees reminds me of a mind-blowing book I was given in first grade. It was called Animals Do the Strangest Things, and it called into question pretty much everything I'd been told so far (at 6) vis-à-vis evolution; namely that people were in charge of animals, people were smarter than animals, people were more inventive than animals and, of course, people were funnier and nicer than animals (none of which turned out to be true). Hughes wants us to understand the world differently; to understand the evolution of ideas and how those ideas shape the choices we make (individually and as a species) and our cultural evolution. He has chosen to do this in what he considers a surreal landscape - America. Now don't get huffy: This is not Baudrillard exclaiming over the American materialist wasteland, or even de Tocqueville marveling in his paternal way over our fabulous optimism; this guy is totally comfortable (maybe too comfortable) with the idea that, grand theories aside, we are not in control of our evolution, any more than the hammerheaded fruit bat, the oarfish, or the naked mole rat. We need new goggles with which to see ourselves and through which to fully appreciate Darwin's work. Hughes has got some.
