Discussion Overview

The discussion explores the origins of kissing, considering various theories and cultural perspectives. Participants examine evolutionary, cultural, and biological explanations, as well as personal anecdotes related to the topic.

Discussion Character

  • Debate/contested
  • Exploratory
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that there could be multiple evolutionary reasons for kissing, noting the need for clarification on the type of kissing being discussed.
  • One viewpoint posits that kissing is entirely cultural and was invented by the Romans, while another counters that it is not cultural in its origins.
  • A hypothesis is presented that kissing may have originated from the need to move food around in the mouth, utilizing sensitive nerves in the lips.
  • Another participant speculates that the origins of kissing could date back hundreds of millions of years, possibly even before dinosaurs, and that remnants of this behavior can be seen in some species today.
  • Some argue that kissing is a learned custom rather than an inherent behavior, citing cultural variations in kissing practices.
  • A suggestion is made that kissing might serve a biological function, such as boosting the immune system or checking compatibility through chemical signals.
  • One participant references a National Geographic special that claims the origin of kissing is related to the pre-digestive chewing of food by mothers for their babies, which is still observed in some cultures and among certain animals.
  • There is a discussion about whether the evolution of kissing between mates is a side-effect of its original purpose related to feeding.
  • Some participants express a more lighthearted view, emphasizing the enjoyment of kissing regardless of its origins.
  • A personal anecdote is shared regarding the impact of pheromones on attraction, suggesting a chemical basis for kissing behavior.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the origins of kissing, with multiple competing views and theories presented throughout the discussion.

Contextual Notes

Participants express uncertainty regarding the definitions and cultural contexts of kissing, as well as the evolutionary implications of their claims. Some arguments rely on anecdotal evidence and personal experiences.

I know one answer to this that is claimed as the correct one. But just for fun, I thought I would throw this our as a trivia question. So if anyone else knows, have at it. If not, I thought it might be fun to see if anyone can figure it out.

Oh geez, I guess there could be all kinds of different evolutionary reasons... Aside from which, you haven't said exactly what kind of kissing you are talking about (as in, between mates, or between a parent and her children).
 
There is nothing inherently natural about kissing. Kissing is entirely cultural. I believe kissing was invented by the Romans.

You should read Tom Robbin's Jitterbug Perfume. It's quite an entertaining story, and it covers what people did before there was kissing.

It seems that both forms have the same origin. But it also would seem that one came before the other. Also, Entropy, it is not cultural in its origins; at least not by this example.
 
in order to better move food around in our mouth and feel what it is we are eating, we developed highly sensitive nerves on the lips. it thus seems to follow naturally that humans in a culture would find a way to take advantage of this pleasurable sensation. just as humans also learned that the genitals are highly sensitive and perceptive to touchand, and give pleasurable feelings upon being touched, so they did with the lips.
 
It could go back as far as 100s of millions of years ago possibly even pre dino.

We do see the origins of this in some species today.

Edit: We also still see the origins of this in a handful or less of primitive human cultures. This is how the determination was made.

No kissing is a learned custom. It is not inherent behavior. If it were, then we would expect to find that every single culture would instinctively kiss. Furthermore, they would kiss the same way. We can find counter-examples for these two statements. Therefore, kissing is not as natural as you think it is.

Sex, on the other hand, is a completely different story.

Might kissing be a way to boost your immune system? Check for compatibilty based on some excreted chemicals?

Yes, IIRC you are right Monique, I can't remember where I heard this but I do remember hearin this (or something simlair).

Since this seems to be racing towards debate, I will fess up and yield the floor.

I saw a National Geographic special that addressed this issue. According to the program, this explanation is the one generally accepted. It was actually about the academic journey to answer this question. I saw this about 8 or 10 years ago.

The answer is: Baby food. The origin of kissing is the pre-digestive chewing of food by a mother for her baby. She then feeds the baby by direct exchange...so to speak. This practice can still be found in some primitive cultures; and of course in other animals.

Ah-ha, and so the evolution of kissing between mates is a side-effect then, right?

This is how I understood things. I think this may also be done at times for the sick or injured...eh,I don't quite remember the details here.

Edit: I find it interesting that with this explanation, we must throw out all preconceived romantic notions about kissing, and recognize its true origins - life itself. No wonder it evolved into a romantic concept. :wink:

But you must admit that in the bad old days, you really had to love someone if kissing was involved. ABC don't work for me!

I believe it is chemically created as a response to pheremones. It exists in other animials and probably in ones which are now extinct even possibly fish. A woman I was once around walked by me. As she did she nearly spun my head off it was not her attractiveness in terms of outter beauty athough she was pretty, but something like a smell but almost magnetic not like perfume but a hundrend times stronger. I approched her containing myself and asked what perfume are you wearing, none she said with a smile it's my scent.

I also believe although I have never read it that people who were of an ingiginous blood through evolution have phermones more readily picked up by members of that breeding area. She was of my area of decent.
