humans have a lot of them.. both males and females have "swollen" lips, compared to most other primates.. and our upright posture, it has been suggested, it what lead to the development of "secondary sexual signals" on our chest. (men get hair, women get enlarged breasts)

there are very few animals that are as fertile as humans.. the average women has 12 to 13 cycles per year..

and like a peacocks tail, some of these might have been a case of selective breeding.. in classic fairy tales, spinsters are not known for their beauty!
