It's not like they use them for any thing. I doubt they are going to BREAST feed any time soon.

The nipples start to develop in the skin before the Y chromosome kicks in to stop further development.

I suspect (but don't quote me) that nipples, finger nails, facial features etc. develop before sexual differences. So all developing embryos get the same things (noses, lips, teeth, nipples, fingers) before the sex of a baby develops.

They're vestigial. Early in mammalian development, we all start out as female. Hormonal cues that determine maleness come after the initial formation of mammary organs.

In fact, the mammalian genitals start from the same structures and then are affected by the fetal hormones to develop into either male or female. The origins of the parts are the same (vagina/scrotum, penis/clitoris, testes/ovaries).

All mammals have nipples becuase they are formed inside the female body, and therefore receive female hormones during development.
