Actually, the reason men have nipples is because both males and females must carry enough DNA to reproduce humans of both genders. So both males and females have the stem cells needed for growing breasts. But since only females have ovaries, generally only maturing and adult females produce enough estrogen to cause their breasts to grow. Males can on occasion develop fully-mature breasts, and that's usually due to a hormone imbalance or due to medication.
The term "supernumerary nipple" applies to individuals (as many as 1 in 50) who have an extra nipple, with or without an extra teat. Men are as likely as women to possess one, but it is often unnoticeably small.
So you can lick them and get yourself "excited"
According to Desmond Morris (The Naked Ape), mammals have twice the teets of the average litter. Typically humans only have one baby at a time.
Believe it or not, yes.
so they can suck on them
Because of a common ancester
Human body has two kidneys
Somebody told me that if you have small nipples when you are younger the chances are that you will have larger breasts when you are older and your nipples will too enlarge
No, nipples are not considered a mucous membrane.

They're humans... Humans have nipples..
Humans are still evolving, and because of that, some people have traits that have mostly disappeared by now, such as thick hair all over their bodies. Many species of mammals have more than two nipples, and it is possible that at some earlier time, proto humans had more than two nipples. Because humans very rarely have multiple births, more that two nipples are not necessary, so we are evolving away from that trait. That is my personal opinion, and I can not back it up with any factual evidence, so don't take it as a fact.
All healthy humans are born with nipples.
Yea they can.
In the development of humans, the default is female. That is the reason that all humans have nipples.
depends, do you mean they are REALY flat or you actually have no nipple??
Pig digestive tracts and nutritional needs are very similar to humans. Pigs also have hearts that are similar in size and makeup to the human heart. Pig heart valves are used to replace defective human heart valves.
Humans are mammals; we have hair all over.
All humans, both male and female, have nipples. The only way a person will not have nipples is if they have been surgically removed. If someone should be born without nipples (either male or female) this is an abormality. Related link: http://en.wikipedia.org/wiki/Nipples
In humans, yes. ("Inferior" in this sense means "below", and if your nipples are above your shoulders, that's a pretty serious birth defect.)
no. he has 2 with two birthmarks that resemble nipples.
No. Have to look around the genital area. Ask a vet or another adult. The only way you could tell the sex of a cat by looking at the nipples would be if it is a nursing mother cat, in which case the breasts of the cat would be hanging lower and filled with milk. Otherwise a male cat's and a female cat's nipples look pretty much the same.
