No one knows exactly when kissing first became a part of human interactions.
In some cultures, kissing is common, while in others it is not.
This suggests that kissing may have more to do with culture than instinct.
But kissing is also seen in other primates, such as bonobos and chimpanzees, which has led scientists to new theories about its origins.
According to Adriano Lameira, an evolutionary psychologist at the University of Warwick, kissing may have started in a rather unexpected (and even a little gross!) way.
He suggests that our ancestors, when grooming each other, used their lips to remove parasites or dead skin.
It was like a grooming session, where, if they found something stuck to a partner’s skin, the primate would use their mouth to help remove it.
Over time, even if cleanliness ceased to be so important, the act of touching lips to another to finish “cleaning” could have remained as a form of affection.
Lameira writes that, as humans lost body hair and the need to clean themselves as much, this final touch of the lips may have survived, serving to strengthen social and family bonds.
Other Explanations and Comparisons:
There have been other theories about the origin of kissing, such as the idea that it began with mothers pre-chewing food for their babies.
However, this theory does not explain the gesture of putting the lips together in a loving way.
Another idea suggests that kissing arose from a behavior of sniffing the other, but this also does not include the participation of the mouth in a convincing way.
Why do humans kiss

Capuchin monkeys stick their fingers in their friends eyes and nostrils to show affection. Why have humans evolved to do so by protruding their lips with a slight suction movement when touching others body?

Link with Social Grooming in Primates:
Lameira points out that primates spend a lot of time grooming and cleaning each other, which helps to create bonds and reduce stress.
Humans, on the other hand, spend much less time on this, because we do not have thick hair and have other means of hygiene.
But even so, we may have preserved this habit in the form of kissing.
Although we can never be completely sure how kissing came about, studying the behavior of other primates and comparing it to our own may give us more clues.
After all, it may be that our habits today still carry echoes of the practices of our ancestors.
And now, try not to think about parasites the next time you kiss someone!
