Also interesting to consider how in some cultures where women routinely go topless, seeing female breasts is no big deal. While in others a nude ankle might drive someone crazy. So clearly there is a cultural component to it, and this video pretends there is none. Why would they do that unless they are going for simple answers to complex questions?
Also interesting how in many species it's the males who invest in peacock feather approaches with visual stimuli to get the females. Then there's the difference in investment of offspring to consider and so much more.
Another good anylsis especially with regard to animal kingdom where my dog , hyenas , Lion et al mark their territtory with Urine and even use it to lure the opposite sex
Moreover, after seeing @surfermarly pic in this post, many men will like what they see...including me , (even if I were to be a catholic priest ) however I will pray for self control....
