Scientists studying chimpanzees and bonobos discovered that physical contact helps these animals avoid conflict during feeding. The research took place at two sanctuaries in the Democratic Republic of Congo and Zambia.
Researchers observed the apes for five minutes before food arrived. During this time, the animals knew peanuts were coming. The team recorded touching, embracing, and kissing among the apes. Those that engaged in reassuring physical contact were more likely to share food peacefully.
Interestingly, even chimpanzees, known for aggression, showed close contact including hand-to-mouth touching. Scientists believe this behavior builds cooperation and trust before potential competition. They suggest this social use of touch may have evolved at least seven million years ago, before humans and great apes split from their common ancestor. The findings provide insight into the evolutionary roots of social behavior.
