Check these out, too...
Breasts are 100-percent biological. Every primate—males and
females—grows breasts, which contain milk-secreting mammary glands. In males,
the mammary glands and breasts remain undeveloped and “flat” because of the
lack of necessary hormones to make them grow. During puberty, however, estrogen
and other hormones promotes the growth of breast buds in females. And there you
have it—that’s why your boobs grow.
As to the purpose, we know the mammary gland provides milk
for infants, but psychologists, biologists and evolutionary scientists have
provided a number of theories for why women grow such prominent breasts. Some
think the size and shape of the human breast helps babies nurse, while others
put it down to sexual attraction.
