The Context

Neanderthals were close human relatives who lived tens of thousands of years ago. Modern humans and Neanderthals interbred in the past.

Previous studies found shared mouth microbes between the groups. This suggests saliva exchange over extended periods.

Kissing serves social and intimate functions in many contexts. Evolutionary roots trace back through human ancestors.

Cultural views celebrate kissing as a universal expression of affection. Biological perspectives examine its health and bonding benefits.

Some find interspecies possibilities intriguing for understanding ancestry. Others focus on how behaviors evolved uniquely in humans.

Researchers build on genetic and behavioral evidence over time. Findings add to knowledge of prehistoric interactions.
