Then 16 bonobos, who weren’t conversant in one another, have been launched one by one into the room with the apple.

Tests confirmed that bonobos have been 4 instances extra prone to climb the fence to launch the piece of apple – with none expectation for payback – when a bonobo was within the adjoining room to obtain it than when the room was empty.
