Kissing goes back 21 million years, to the common ancestor of humans and other large apes, study finds
  • Recent research indicates that kissing can be traced back to a primate ancestor from around 21 million years ago, suggesting a deep evolutionary connection between this behavior and the lineage of large apes and humans.
  • Understanding the origins of kissing provides insights into social behaviors that may have evolved in response to environmental and social pressures faced by early primates.
  • This discovery aligns with ongoing discussions in the scientific community regarding human evolution, particularly in relation to how social behaviors have developed and adapted over millions of years.
