Question about breasts?
Why do humans have them even before we ever give birth? my understanding is that they are primarily in most mammals for feeding infants so why do we have them all the time?

Their primary purpose it to attract a mate. Most mammals do not have huge breasts. Their young can be fed quite adequately with nipples alone.

Because that is what natural selection produced. It is probably far easier for breasts to develop in the foetus than for an adult female to develop them during gestation. Enough energy and nutrients go from the female to the embryo to enable it to develop. She does not really have enough energy and nutrients to also develop an entirely new anatomical structure at the same time.

because human are fertile any part of the year, and they dont disappear in other mammals whenever they dont have babies, their breast tissue is still there, its just they are so obviously placed on humans its easy to forget al mammals have them. also, through selective breeding, (i.e. men liking women with larger breasts, and women liking men with larger penises leads to people with genes promoting larger breasts and penises through generation after generation

ALL mammals have them "all the time" That is one reason they are called mammals.
