The Good Gene Hypothesis suggests that the traits females choose when selecting a breeding mate are true indicators of a male partner’s ability to pass on genes that will increase the survival or reproductive success of their offspring. There are a couple of ways females naturally select mates with a better gene pool, with one being using body symmetry as a selection factor. Symmetry is when dual body parts on a human body are equivalent to each other. For example, if both of your wrists, ankles, and knees are pretty much equal in size to each other, it’s said that they are symmetrical. For a long time there has been a belief that body or facial symmetry can predict human health. There are two types of symmetry: low and high symmetry. Low symmetry is believed to be a predictor of poor genetics, low physical and mental health, as well as poor cognitive skill and IQ. On the other hand, it’s believed that high body symmetry is a good predictor that people will potentially have healthy offspring. It’s obvious that low symmetry is very difficult to detect by looking at a body with the naked eye, so, nature has given us the ability to smell one’s body symmetry. Of course it’s impossible to smell body symmetry off say a person’s wrist for example. However, it turns out that women can smell odors that result as an effect of physiological processes in men that have symmetrical bodies while they are in their fertile phase. A woman will be able to basically smell symmetry in a man. Also, women on their fertile phase rate the odor of more dominant males as sexier than the odors of less dominant males. Also, women in this phase rate the odor of more dominant males as sexier than the odors of less dominant males. A woman who is not currently in her fertile phase does not have these preferences though. So, if you are a male with high body symmetry, you are more likely to have luck finding a romantic partner, especially if she is in her fertile phase when you meet or are with her.

I really enjoyed reading your post! When I initially read about this in the PowerPoint slides I found the topic to be very intriguing. Although I am still skeptical about whether or not body symmetry is a quality indicator of producing a healthy offspring, I still find that the concept itself gets me thinking! Your post was overall great and I appreciate the topic you chose to write about as well!!
