The chimps that never forget: ‘It is impressive that they remember where the ants are’
A study by the Jane Goodall Institute Spain and the University of Barcelona shows that chimpanzees remember the exact location of concealed ant hills
The secret camera is activated, a sign that a wild animal has passed in front of it. It is dry season and Hiila, a savannah chimpanzee, walks determinedly towards her target. She stops, pushes aside a layer of dry leaves with her hand, puts her nose to the ground and inserts a finger into a small hole. Bad luck, no ants this time. So how did she know there was an ant hill there?
