It is curious how there seems to be an instinctive disgust in Man for his nearest ancestors and relations. If only Darwin could conscientiously have traced man back to the Elephant or the Lion or the Antelope, how much ridicule and prejudice would have been spared to the doctrine of Evolution.
Havelock EllisThe sexual regions constitute a particularly vulnerable spot, and remain so even in man, and the need for their protection which thus exists conflicts with the prominent display required for sexual allurement. This end is far more effectively attained, with greater advantage and less disadvantage, by concentrating the chief ensigns of sexual attractiveness on the upper and more conspicuous parts of the body. This method is well-nigh universal among animals as well as in man.
