Neanderthals and early humans likely kissed, study suggests

A study from the University of Oxford suggests that Neanderthals and early humans likely kissed, and might even have kissed each other.

Why it matters

  • The study sheds light on the evolutionary origins of kissing.
  • It suggests that kissing behavior might have been present in Neanderthals and early humans.
  • This finding adds a new dimension to our understanding of human-Neanderthal interactions.

By the numbers

  • Kissing is suggested to have evolved between 21.5 million and 16.9 million years ago.
  • The study focused on reports of kissing in primates from Africa and Asia.

The big picture

  • Kissing is not unique to humans and is seen in a variety of species.
  • The behavior could have been used for both sexual and platonic bonding.
  • The study supports the idea that Neanderthals and humans interacted intimately.

What they're saying

  • Experts suggest that kissing behavior's origins lie deep in our evolutionary past.
  • Kissing has a cultural element and is not common to all societies.
  • The behavior could have been important for promoting trust and intimacy for millions of years.

Caveats

  • The study is based on observations and reports, which might not be entirely accurate.
  • The exact nature of human-Neanderthal interactions remains speculative.

What’s next

  • Further research could explore the cultural and evolutionary significance of kissing in more detail.
  • Studies might investigate kissing behaviors in a wider variety of species to push its origins back even earlier.
