An interesting meme in this week’s Economist magazine, from a more
general article on human evolution–the idea that, as with a peacock’s
feathers, smarts is a rapidly evolving surogate for excellent genes,
above and beyond its actual ability to increase fitness. Interestingly,
the authors posit, unlike the peacock’s feathers, it’s not sex-linked.
