Bonobos Demonstrate Theory of Mind by Recognizing Human Ignorance

A new study reveals that bonobos can identify when humans lack information and communicate to help them, showcasing advanced cognitive abilities.

Researchers from Johns Hopkins University studied three male bonobos at the Ape Initiative in Iowa to explore their cognitive abilities.
The study found that bonobos could recognize when a human partner did not know the location of a hidden treat and would point to guide them.
This behavior demonstrates 'theory of mind,' the ability to understand and act on another's perspective, previously thought to be unique to humans.
The findings suggest that this cognitive trait may have been present in the last common ancestor of humans and great apes millions of years ago.
While the study was conducted in a controlled environment with captive bonobos, it provides significant insights into the social and cognitive complexity of these endangered primates.
