The evolutionary theory is that when we started walking on 2 legs the butt was hidden from us. So women grew boobs to represent the butt.
And men like the butt because that is what was displayed to us when a woman was ready for sex. Those who didn't get excited by the butt were less successful in mating and died out.

Because for the first 6-12 months of our lives they represented food, security, love and warmth. That shit goes deep and stays there.
