Comments on: Women's sense of smell evolved to sniff out bad mates http://boingboing.net/2009/04/07/womens-sense-of-smel.html Brain candy for Happy Mutants Mon, 20 May 2013 09:01:00 +0000 hourly 1 http://wordpress.org/?v=3.4.1 By: Noctis http://boingboing.net/2009/04/07/womens-sense-of-smel.html#comment-459272 Noctis Wed, 30 Nov -0001 00:00:00 +0000 #comment-459272 Meh, so much of this is cultural. Studies using American college students show that women can distinguish more colors than men, but the results *don't hold when testing subjects from nonwestern cultures*. Turns out that distinguishing colors is a trait one can learn, and female-reared people in the U.S. are expected to be able to tell the difference between turquoise and teal, while male-reared people are not. That said, progesterone heightens the sense of smell, which makes sense, since it is high in pregnant women, who should avoid eating tainted foods. But other than that, a sex difference does not make sense unless you assume that human men really don't have much involvement in mate-partnering, which is empirically false. Men are involved in childrearing, and like women have a genetic interest in doing so with a good partner. Meh, so much of this is cultural.

I love neat little theories like this, but wonder whether it's been out there widely, and confirmed or debunked.

Use lexis nexis. Then instead of bleeting randomly on the internet, you could be informed. Oh, person who said that men and women have the same number of offspring -- "in a balanced population" -- you are denying fundamental evolutionary facts about our nearest animal cousins, and us.

If women truly have a more sensitive sense of smell, isn't it more likely related to progesterone, which serves an immediate purpose during pregnancy? This sniffing out of potential mates seems a lot less evolutionarily likely than the ability to avoid foods that would hurt a fetus. What Noctis said.

It's pretty difficult thing to say we evolved a trait for a certain specific reason, given all the unknown factors that have been going on for hundreds of thousands of years.

I was a big sniffer of my babies, particularly the back of the neck. I do know there was one experiment of women choosing their own babies by smell alone. All mammals smell their young,I know i did and 50 years later can recall the smell.

They got these women to spend a week wearing their shirts and doing lots of exercise. Then they got some men to rate the smell of the sweat based on how much they liked it, then they compared each persons genetics in the test with other. Turned out the men very accurately rated the sweat by how genetically close they were to each other, where the nicer the smell was, the more distant genetically the person was.

His intriguing test was similar, only he was meant to rate the shirts on how attracted he was to the smell. Some he hated, some he loved. The nicer the smell, the more he was attracted - i.e. inbuilt genetic mechanism to prevent us shagging our sisters. Good, eh? Ol' Mother Nature knew what she was doing.
