What is the evolutionary benefit of kissing?

gargygirl02: What is the evolutionary benefit of kissing?
Considering that kissing releases endorphins, there must be some benefit to it (feel free to correct me if that is an incorrect assumption). So what is the benefit of kissing, and why do humans kiss when a species such as chimpanzees don’t?

Answer by Someone
It helps to encourage sexual arousal. It’s because you get eye contact, taste of lips and smell of an opponent.
It’s because of a human discipline. monkeys can watch in each other eyes and smell each other. People are trying to not to look at someone too much if he sees him and won’t try to smell other people although nature wants us to do it, so when we kiss, we make what nature makes us to do after quite long of holding it in yourself so we fell good.
Btw. that’s very good question.

‘Someone’ has given a pretty good answer, but I would add that it’s another social interaction that reinforces the pair bond. In humans, the pair needs to stay together for 10-16 years (depending on race) to rear a child to maturity, and so evolution has developed many more pleasurable things to do to each other than just picking fleas.

Sorry, that’s not very romantic, but it’s true!
