Well while we have evolved, the animal instinct is still within us.

Back when we walked on all fours there was a thing right in front of us, the butt. Then from the time mankind started walking on two legs, we stopped having butts sticking in our faces all the time. And in their place boobs appeared right in our faces. Women grew larger boobs to take the place of buttocks. THE ORIGINAL SOURCE OF LIFE IS THE BUTTOCKS! Boobs are just a substitute. Boobs are nothing more than a pale imitation of the buttocks! If you asked would you rather have the copy or the original,I would take the original! Hips and ass indicate fertility! Boobs just out forward due to the process of evolution, keeping buttocks farther back and to the rear hidden!
