Why do men have nipples since they cannot nurse children?

Question

Why do men have nipples since they cannot nurse children?

Answer 1

Actually I saw something on the discovery channel about that. They used this example: Back when there were caveman and the mother dies, the baby had to be feed somehow and the men would actually start to produce milk for the baby so it can survive. I believe they said that it's  physiological. Here is a website you can look at for more info.

Answer 2

by default our bodies are female- so all fetuses whether male or female have nipples. there are also rare cases where there is male lactation to feed children.

Answer 3

From conception until sexual differentiation, all mammalian fetuses within the same species look the same, regardless of s*x. In humans this lasts for around 14 weeks after which, genetically-male fetuses begin producing male hormones such as testosterone but at that point they already have nipples.
