Humans have been kissing since at least 2500 B.C. According to ancient cuneiform tablets found in Iraq , humans have been smooching since 2500 BC .
Primates are the only animals who can "kiss" using puckered lips the way humans do; other species don't have the necessary anatomy.
The full spectrum of human kissing sets us apart from the rest of the animal kingdom.
Food sharing is also a big motivator for mouth-to-mouth contact in bonobos.
Other animals might share behaviors that resemble kissing in form or function, but the full spectrum is still unknown.
