→A man's physical attractiveness predicts how long he waits before a woman will allow sex

To some extent this result can be regarded as evidence for the Sexy Sons hypothesis, proposed by statistician and geneticist Ronald Fisher (1930). His theory—expanding upon Darwin's much overlooked emphasis on the sexual selection for male traits by females—states that [[beauty]] may have evolved by a feedback loop ([[Fisherian runaway]]) to become so attractive that women are readily willing to copulate with a beautiful male irrespective of other considerations (e.g. his ability or willingness to provide for and protect the female), because the males' beauty—which is partly heritable—confer on their offspring a potential reproductive advantage. The same does hold true for the opposite case i.e. men more readily copulate with beautiful women, but men can afford to be much more less selective/more promiscuous in any case because they do not need to pay the cost of carrying and giving birth to the child and do not need to consider women's ability to provide ([[Bateman's Principle]] of differential parental investment). Hence, women's behavior of disregarding the ability to provide merely at the benefit of better looking offspring has much more drastic implications. | To some extent this result can be regarded as evidence for the Sexy Sons hypothesis, proposed by statistician and geneticist Ronald Fisher (1930).

The result is also evidence of female ''coyness'' (i.e. reluctance to mate). It has been proposed that women use this behavior to evaluate the man's suitability as provider (McNamara 2008, Wachtmeister 1999), but also to ensure that there is still an opportunity for a better male to show up in the meanwhile. Evidently women regard such evaluation as less necessary when the man is good looking. | |||
