The sexy son hypothesis in evolutionary biology and sexual selection—proposed by Ronald Fisher in 1930—states that a female's ideal mate choice among potential mates is one whose genes will produce male offspring with the best chance of [[reproductive success]]. The type of men whom achieve the most reproductive success depends on the social system. For example, a sexy son in a strict patriarchy will look extraordinarily different than a sexy son in a strict matriarchy. | The sexy son hypothesis in evolutionary biology and sexual selection—proposed by Ronald Fisher in 1930—states that a female's ideal mate choice among potential mates is one whose genes will produce male offspring with the best chance of [[reproductive success]].{{#ev:youtube|https://www.youtube.com/watch?v=lq0b0npXSrM|frame|}} | ||
The man above is a prime example of fisherian runaway in a human male. Comically long ramus, jaw completely parallel to the floor, and a hilariously short philtrum. Indian women have an extreme preference for birthing sons. <ref>https://www.reuters.com/article/us-india-women-rights/india-has-21-million-unwanted-girls-due-to-preference-for-sons-idUSKBN1FJ1PN</ref> | |||

Since having sexy sons stems from women choosing the mate they are most physically attracted too, the male equivalent is doing the same thing (resulting in sexy daughters). Males choosing women they were most physically attracted too has been the norm for most groups of people thru out human history. | Since having sexy sons stems from women choosing the mate they are most physically attracted too, the male equivalent is doing the same thing (resulting in sexy daughters).
