I remember a Darwinian article in Time (Asia) Magazine’s special issue, The New Age of Discovery (January, 1998) because it tried to answer questions like why do we find certain human body figures sexy. It said that most men find a specific waist-to-hip ratio (WHR) of women sexy (now I won’t tell the exact figure to avoid causing unnecessary insecurities) because that ratio signals fertility. Men don’t consciously know this, but evolution somehow programmed it in our instincts to ensure the perpetuation of our genes.
In another article, I read about an experiment on human scent. It involved a certain number of men and an equal number of women. The men were made to shower using only unscented soap (no cologne or deodorant either) and sleep with a white shirt on. They would shower again on the second night but would wear the same shirt to bed. Then the shirts would be sniffed by the women, who would each try to determine which shirt smells the “sexiest”. After their genes were tested, it was found out that the sexiest scents for most of the women belonged to the men whose genes were very much dissimilar from theirs. Parents with diverse genes often bear stronger offspring, and once again evolution has hardwired this into our physiology to help us find a suitable mate – and perpetuate our genes.
But in this overpopulated modern society of ours, procreation is no longer the primarily purpose of sex. In one of our joint articles, a fellow freethinker wrote:
Sex may lead to pro-creation but the two are still two totally distinct acts, no matter how much some belief systems may insist that they’re one and the same. When you start a fire, you aren’t obligated to go cook something. Sometimes, it’s enough just to enjoy the warmth of a blazing fire on a cold night. The same goes for sex. It’s a social activity and a recreational sport as well. From a liberal point of view, it’s not even that different from a couple going dancing (that’s why it’s also called the horizontal tango).
Still, our instincts kick in when a genetically suitable specimen from the opposite gender walks by even if having kids is the last thing on our minds. But as we get to know a person, after a while we get attracted to non-physical traits like kindness and a sense of humor. Perhaps we instinctively know that certain personal attributes are preferable for long-term companionship, especially when it comes to the point when procreation and even sex are no longer possible.
But the beauty of these personal qualities is that they can be enjoyed now as much as in the future. Being the most highly evolved among all creatures, humans interact in ways beyond touching and smelling. A nice conversation connects us more profoundly than two chimps grooming each other. Although touching is nice, it is often meaningless unless coupled with an emotional bond. And so while evolution already dictated what we should find physically attractive, it is our longing for a deeper connection that needs to be satisfied if we are to truly enjoy being human.
