Is the fatty tissue that comprises most of a breast necessary? Could women 
breast feed without having enlarged/noticible breasts? Have breasts 
developed some other purpose, such as a sex signal? - I believe that I saw 
a program on the Discovery Channel, and they proposed that the enlarged 
breasts of women developed as a sex signal.
