Obviously if somebody is too large, that means they might die of a heart attack or something and reduces their appeal, and if they’re too twig-like, that means they’ll die of anorexia, but taking a look at the people within two standard deviations of the normal distribution, by most part different men will be attracted to different parts of the curve.

If preferences were significantly narrow, we would probably be producing offspring within those narrow parameters.

This seems a little sweeping, or trivially true. It almost sounds like something you would hear on Oprah – “don’t worry, different guys like different faces, body shapes, and so on – and Mr. Right will cherish you for whatever you are.” Yes, different guys like different things, but that ignores probabilities.
