I'm talking about guys like this:
That's more than "differing amounts of body hair." Why did the designer give us a gene that could do that if he didn't expect us to ever have to use it?
I asked why evolution would produce something so unnecessary [male nipples] and didn't get an answer.
Cecil Adams says: "To tell you the truth, nobody really knows. The best explanation I've been able to find (and frankly it doesn't explain very much) is that nipples aren't a sex-linked characteristic. In other words, nipples are just one of those sexually neutral pieces of equipment, like arms or brains, that humans get regardless of sex."
I don't know if anybody has a better answer than that. You will ask, Why hasn't evolution gotten rid of them? And I will reply, There's no requirement that evolution get rid of something that's essentially harmless.
Okay, your turn. Why did the designer give men nipples?
To give an angry woman something to twist.
I don’t suppose either side has a good answer for nipples, but why don’t people have more eyes, or more arms?
I think the information can be present in a gene, but yet not necessarily be meant for application in the way manifested in that picture of the boy with the excessive facial hair.
Here's the evolutionary answer, from The Evolution of Man by Wilhelm Boelsche...
"For we find the instructive law on the resemblances of the youthful forms to their ancestors gives us a very satisfactory clue to our original ancestor: the body of the human being in the mother's womb is also, in its first stages, covered with thick woolly hair. Even the face is covered just as we see it to-day in the case of the adult gibbon, and only the inner surfaces of the hands and feet are left free. Evidently these free places were uncovered, even in the ancestor which this human embryo copies for a short time. This Esau-like covering of the human being does not disappear until immediately before birth, and in a few exceptional cases, this covering has even been retained during life. This is the origin of the renowned men with dog faces."
