First kiss dates back 21 million years, say scientists Open in Bbc.com
Highlights
  • Kissing is ubiquitous among many animals, especially primates, suggesting deep evolutionary roots of the behavior.
  • The team ultimately defined kissing as a non-agonistic interaction involving directed, intraspecific, oral-oral contact with some movement of the lips\/mouthparts and no food transfer.
  • Neanderthals and our own species, Homo sapiens, are known to have interbred —plus they also shared oral microbes—the team speculates that Neanderthals and our own human ancestors might have kissed as well.
