The most commonly cited theory about kissing goes to an observation by ethologist Irenäus Eibl-Eibesfeldt, who noticed that in certain human cultures, mothers will chew food up, then kiss the baby, transferring the food into its mouth. This motherly kiss could have carried over to adult relations, producing the other forms of kissing.
