ABSTRACT
Between 1967 and 1997, an interesting dialogue about breasts took place among a group of scholars of evolution. They asked the question: "Why do women have permanently enlarged breasts?" The breasts of all other mammals swell only during lactation then shrink away when the milk dries up. Only women go about with full, rounded breasts even when they are not making milk. The theory of natural selection holds that evolution has favored the best adaptations. Therefore, permanently enlarged breasts must have evolved for a reason. What could that reason be?
