Were we created aesthetically or did we develop our attractions subjectively? For example, it seems as though every little detail of the human body has a utilitarian function to it. Eyebrows as sweatbands for your eyes, fingernails for breaking things apart, bellybuttons as grape-holders, etc. So, is there any part of the human body that is not utilitarian, but purely for the aesthetic purposes of attracting the opposite sex? Or, do we develop our attractions simply based on comparing our options?
