Bonobos show they can understand when humans don't know the location of hidden treats.

A new study suggests that bonobos can understand and react to a human's lack of knowledge, pointing to hidden treats when they know humans don't know where they are. This "theory of mind" ability implies that bonobos, like humans, can hold and adjust to different mental states. The findings, involving three male bonobos, support the idea that advanced social cognition may have evolved in our common ancestors millions of years ago.
