First kiss dates back 21M years

I assume kissing comes from a parent chewing up food and then transferring it to the baby.

This is innate “caring” behavior.

Similarly, mammary glands are for providing milk/nutrition.

These get associated with primal needs and therefore the amygdala, and so is associated with strong emotion.

Kissing is so weird. You can make up a thousand just-so stories. You can imagine it meant totally different things through time and across cultures.

For me it just seems like yet another culturally-defined signal of intimacy. Like showing ankles or chests or saying this or that. Seems to me trying to make everything some hard wired evolutionary thing is a dead end.

Many people kiss animals but can't kiss another human from a country X, culture Y or who has opinion Z.

I'd rather kiss my dog, whom I love, over a random person that I have little in common with. Is that somehow weird to you?
