Caveman give woman food. Woman hungry. Woman let caveman smash. Cavewoman live long and healthy. Cavewoman make babies. Babies survive because caveman give food. Good genes tell caveboys: give food to hot woman and smash. Good genes tell cavegirls: caveman who give food=daddy. Everyone have healthy grandbabies. Grandbabies survive. Good genes spread. -Charles Darwin; On the Origin of Species’. Vol 4, Ch 3; Descent of Man
