Symmetry is elements that are symmetrical to each other, whether it be shape, size, position, etc. It is said that symmetry is an important part of attractiveness and even scent tracking. Low symmetry is predictive of worse genetic, physical, mental health, cognitive skills, etc. It has been known that even in animals that low body symmetry causes problems. For example, in the text, See What I'm Saying: The Extraordinary Powers of Our Five Senses, it states, “It’s long been known that low body symmetry in animals can be a result of genetic abnormalities caused by in-breeding, mutations, and other factors. Low body symmetry in animals is predictive of slower growth rates, reduced longevity, and reduced fertility”(Rosenblum, n.d.).
However, high symmetry equals size of body parts and are generally more attractive. For example, research has shown that men typically have more relationships. In the text, it said, “men with high symmetry (more equal wrists and ankles) typically have more sexual partners, quicker access to romantic partners, and induce more copulatory orgasms in their mates. So, it turns out that size does matter after all: bilateral equivalence of appendage size, that is”(Rosenblum, n.d.). It is interesting and true that humans are more attractive to symmetrical faces that asymmetrical.
