The Times Online
reports on a recent study by University of Helsinki researcher Markus Jokela, who found that women are getting more beautiful:
Scientists have found that evolution is driving women to become ever more beautiful, while men remain as aesthetically unappealing as their caveman ancestors.
The article doesn't mention where Jokela published his study, so I'll have to go by the article's description of his work. But on the basis of that, his claim is absurd. Beauty isn't something like height that can be objectively tracked and measured over time. Standards of beauty change over time and across cultures. Which makes it meaningless to say that women are getting more beautiful.
The Gene Expression
blog also criticizes Jokela's claim, pointing out that "males and females inherit half their genes from an opposite sex parent." Which means that if gorgeous women are mating with ugly cavemen, their children will be half ugly caveman, which contradicts Jokela's thesis.
