Why do we humans kiss?

Asked by AstroChuck (37378points) August 7th, 2008 from iPhone

It isn’t something that we have in common with other animals. We share the urge to mate but not kissing. Is kissing evolved behavior? Is there evidence suggesting that kissing predates civilization? When isolated aborigine peoples are discovered do they sometimes find a community that doesn’t kiss? Perhaps these people show affection differently such as Inuits and “Eskimo kissing.”

FEELINGS ARE BORING. KISSING IS AWESOME.

On a more serious note, I copied the following from wikipedia:

“Anthropologists have not reached a consensus as to whether kissing is a learned or an instinctive behavior. Kissing may lead to sexual behaviors. It may be related to grooming behavior also seen between other animals, or arising as a result of mothers premasticating food for their children. When mammalian mothers kiss infants, their bodies automatically recognize biological dangers to their offspring, and their bodies add resistant proteins to their milk. Kissing allows prospective mates to smell and taste each other’s pheromones for biological compatibility. Women are subconsciously more attracted to men whose major histocompatibility complex portion of their genome is different from their own, leading to offspring with resistance to a greater number of diseases due to heterosis, and thus having a better chance of survival. This explains why couples are more likely to bond if they have the right “chemistry.”

Non-human primates also exhibit kissing behavior. Other than primates there are also animals, particularly many species of birds that exhibit beak-to-beak and mouth-to-mouth behavior which is typically interpreted by observers as kissing. Dogs, cats, and other animals display licking and grooming behavior among themselves, but also towards humans or other species. This is sometimes interpreted by observers as a type of kissing, but some may see this as anthropomorphising the actions of animals.”

I’m not sure kissing exists in all cultures. And I have met people who say they do not like to kiss. To me kissing is the one sure way to know if I am hot for someone. Have you ever kissed someone and felt nothing? I guess this adds to melted’s post, except, I’m not too sure the compatible mate theory works for us homos. That’s right, I said it. :)

I vaguely remember a quote along the lines of “Kissing is a lovely trick designed by nature when words get in the way.”

hmm I am not really an expert of any kind, but my intuition tells me its just something natural people do, as opposed to a learned behavior, even like eskimo kissing, it is natural to bring the faces together. I just thought they didn’t kiss cause their faces freeze together or something lol.

yeah, it’s sort of weird. kissing doesn’t really do a whole lot for me. i don’t see what the big deal is, my friends think i’m absolutely crazy.

Perhaps-

Face-to-face mating, combined with a more omnivorous jawline/tooth shape (smaller canines, less teeth clicking together). Also, a sense of trust and intimacy developed by sharing the oral cavity (the place nutrition goes) with a mate. A mate that a pre-paleolithic human would not have to worry about stealing their food. I don’t think I’m explaining myself well…

Maybe just because it’s so much fun.

@Knot; Part A is a great synopsis for your thesis.

@knot: I think that turned me on?!!

There are few parts that are as sensitive as the lips and tongue. Depending on the type of kiss, it’s stimulation or tenderness.

Kissing makes you feel good!

@knot: way too technical! @loser: I worry about you…
