This is a thought-provoking study. Thank you, Arjun, for sharing.
What men/women find attractive in potential mates in both physical characteristics and in behavior correlates subconsciously with their reproducibility and potential capabilities as a partner. It's simply how we've been wired through millennia of reproduction as a surviving species and it's not really a new concept at all. Often times, these attractive traits are a combination of genetics and acquired and learned behaviors/characteristics that are not passed down genetically. For example, dancing.
The concept of the dancing in the scope of evolution and natural selection has always fascinated me. The ability to dance has been universally accepted as an attractive ability by both men and female, but what it exactly conveys to potential mates doesn't seem so obvious. To me, being able to dance conveys the ability to control your body with precision and having a sense of music and beat that isn't necessarily limited to auditory senses (aka deaf dancers). According to the study, dancers exhibit "a heightened sense of communication, often of a symbolic and ceremonial nature, and a strong spiritual personality trait". Not sure if I completely agree but it's definitely something to think about and ponder upon.
