1) Women have nipples for the purpose of breast feeding.
2) Unlike women, men have nipples for no reason.
3) Nipples come from nature.
C) It is not the case that nature is purpose driven.
I don't think that makes sense. It's true that men don't make milk, but a) it could have been that some early mammals' males DID make milk; b) there may be added efficiency in not differentiating body parts. For example, many parts of the penis and vagina are actually shared structures, and they differentiate as the fetus develops; this saves energy during the crucial early development of the fetus.
It's just that evolutionary purpose is one about statistical persistence-- not necessarily the apparent outer "purpose" of an adult organisim.
