Some of you guys are confusing evolution with Lamarckism. Quote: "[Lamarckism is the belief that] individual efforts during the lifetime of the organisms were the main mechanism driving species to adaptation, as they supposedly would acquire adaptive changes and pass them on to offspring." One alpha male's (or a whole tribe's, for that matter) predilection for shaved babes does not lead to a process of natural selection whereby we shed our hair in an effort to appear more fuckable to the socio-cultural flavour of the month. There is no exo-human (pardon my neologism) benefit to the species as a whole. A commonly used example to illustrate this fallacy is that the Jews, who have been circumcising their males for thousands of years, are not born with penises any different to other Homo sapien males, and they never will. Don't get me wrong; I'm all for the quirky and unorthodox corners of science, way outside the mainstream, but Lamarckism is pretty silly and banal stuff. I like a little imagination behind my pseudo-science... Sheldrake's theory of Morphogenetic fields, anybody? Furthermore, I have a second-hand bookstore and I come across a lot of old erotica. And I mean a lot! Lots of books from the 19th century, but also contemporary collections exhibiting the history of erotica throughout the world (it's a gigantic area of art publishing). Outside of a few examples during the Renaissance, and in pre-Meiji restoration Japan, and in the work of some of the Dutch Masters, it really isn't until the mid 20th century, in the Anglophone world specifically, that hairless women are considered in any way attractive.
