Did this study actually look at the DNA of men to see if they had superior DNA? Are looks and income/accomplishment the only measurements of superior DNA?
The study makes sense to a point. But the statement of the conclusion is rather weird.
Let's first look some of the primary things that attacks men to women: looks are apparently #1. Then comes what he things/feels about her.
Does this mean that a man's orgasm is a trick used by the bodies of men to select which women he passes on his genes to?
Note that a woman does not have to orgasm to get pregnant. Or to say that female orgasms are a trick by the bodies of women to weed out the genes of less desirable men makes little sense.
Now if one wanted to say that women would be more likely to orgasm during sex with a man that she considers more desirable (good looking, accomplished, etc.), yea that makes sense. It's because just like with men, women prefer sex with partners that they find highly desirable.
orgasms may help women get pregnant though. some species the female has to orgasm to ovulate, but in humans there is signs that show sperm get sucked up into the fertile ovary's tube by the orgasm. So it is possible that it is a selective process.
However, men have only one concern when spreading their seed biologically; it takes about 40 mins to regenerate a batch, concerns over std, territorial dispute with other male. Women have to balance good provider with good genetics. Men can find a horrible provider, if genetics are good, it's not much resource expenditure. Women can get good genetics, but they are gambling a lot more resources on it than a man is.
I think women and men have a lot in common with selectivity of genetics, i think men idealistically want the best they can find, but will settle more easily than a woman will on looks. Women however will trade looks for a good provider.
Also what defines good genetics for men and women are both similar, symmetry, healthy looking features etc.. A man might be a capable provider but not a willing provider, that is why women have to be deeper with the personality where as men can be less selective about personality. Men are looking for a young fertile healthy baby maker, women on the other hand don't care about youthfulness as much as they are more deeper thinking on the issue. An older man might be a better and more willing provider while still carrying good genetics. That is why more women can find older men attractive still where as a 25 year old man seldom find a 60 year old woman as an acceptable mate.
