Kissing is not universal among human beings. Even today, there are some cultures from which it is completely absent. This suggests that it is not innate or intuitive, as it so often seems to us.
One possibility is that it is a learned behavior that evolved from "kiss feeding," the process by which mothers in some cultures feed their babies by passing masticated food from mouth-to-mouth. However, there are some contemporary indigenous cultures which still practice kiss feeding, but not social or erotic kissing. Another possibility is that kissing is a culturally-determined form of grooming behavior, or, at least in the case of erotic or deep kissing, a representation, substitute for, and complement to, penetrative intercourse.
