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.

Except that as the article says many animals kiss, not just humans.
