The Science of Sex Appeal
Call me a closet-nerd all you want, but nine times out of ten if my TV is on I’m watching the Discovery Channel (that or one of VH1’s CelebReality shows). Along with the nature documentaries, and wilderness and science series, they tend to have really good specials. Last weekend I happened to catch one called “The Science of Sex Appeal” that broke down the evolution of human sexuality and courtship behavior. To call it interesting would be an understatement, as the two-hour special covered a wide array of topics.
In one segment they broke down why women have such a keen sense of smell. If I had a penny got laid every time I’ve heard women say she had a sensitive nose I wouldn’t be able to walk straight. According to the documentary, women’s sense of smell helps with choosing mates because we’re all wired to have chemical attraction to certain people’s scents. Smell also helps us avoid taboos like incest. During one of the experiments, a group of women were asked to sniff several men’s sweaty T-shirts and they all were repelled by the scent of blood relatives. Since smell plays such a big role in attraction, I guess that explains why I like sniffing some girl’s armpits (so what). I always thought it was a fetish, but the documentary showed that a lot of people do the same thing.
The special also talked about monogamy and promiscuity. Some species of animals mate for life and they found that those animals tended to have an abundance of a particular chemical in their brains, which could be dubbed a “love hormone” of sorts. They found the same chemical in human brains as well. People who were monogamous tend to have more, while the promiscuous folks have less. So is it possible that certain people have a chemical disposition towards cheating? Hmmm.
Did you know that proportionally speaking human males have larger penises than other primates like gorillas? The reason being is that we have sex face-to-face as opposed to doggy style like the rest of the animal kingdom. Walking upright caused the human female’s genitalia to shift positions, requiring a longer penis to reach her G-spot from the front. I guess that’s why backshots feel deeper (and better).
While walking on two legs allowed human females to carry their young, it also limited their ability to gather food and defend their young during formative years. Researchers believe that this led to humans building monogamous family structures because females need the assistance of males for added protection and child rearing. As an added bonus, there’s a theory that women—one of the only species that can have intercourse year round—evolved that way as a means to keep men around.
There’s a host of other interesting tidbits, like how women’s voices become sexier to men when they’re ovulating; how symmetry plays a role in what we view as attractive; why women are pickier at selecting mates than men; how men and women walk differently when they’re in heat, and why we’re drawn to certain body types. Maybe it’s just me, but I found the show extremely interesting and informative. CLICK HERE for the Discovery Channel’s breakdown of all the segments but I included links to a few key ones below. They’re only about two-three minutes each, so check them out when you get a minute.
Do you think we have a genetic predisposition to being attracted to certain people? Have you found yourself attracted to a particular lover’s scent? Do you think genetics and evolution play a role in monogamous relationships? Do women find that they feel sexier when they’re ovulating? Do you think that there could be a “love hormone?”
