basically like. why do women just have breasts all the time when to my knowledge the only purpose of them is to feed children. why don’t they go away like other mammals’ when you haven’t had a child.
In: Biology
The short answer is because men like them. Other apes don’t have breasts like humans do, and the reason why is because they attract mates in a different way. Female chimps signal sexual receptivity with a genital swelling, which is very easy to see. Chimps are knuckle walkers and don’t need the large gluteal muscles that humans have for upright walking. As humans evolved to walk upright, the sexual signals our ancestors used became less effective, so they were lost and new ones evolved in their place. Permanently swollen breasts are a sign that a woman is sexually mature and serve as an advertisement to men
