Paleo may look like a food fad, and yet you could argue that it’s really just the reverse. Anatomically modern humans have, after all, been around for about two hundred thousand years. The genus Homo goes back another two million years or so. On the timescale of evolutionary history, it’s agriculture that’s the fad.
