Chimpanzees and other great apes were found to have a behaviour that was previously thought to be exclusive to humans, says expert.
Scientists using homemade videos featuring a person in a King Kong costume have documented a remarkable cognitive skill shared by chimpanzees, bonobos and orangutans: the human-like ability to recognise when someone else's beliefs are wrong.
The research demonstrated that these great apes, humankind's closest living evolutionary cousins, possess a capability thought until now to have been the exclusive domain of people, the scientists said recently.
