Chimpanzees and human beings are very similar…yet different. Chimpanzees can do things we humans cannot, and we can do things chimpanzees cannot. Finding these differences allows us to explore the wonders of being human and reminds us of what makes us special. Mother and son chimpanzees Ai and Ayumu have learned language and numbers. Ayumu is able to instantly memorize numbers randomly displayed on a touch screen and sequence them in ascending order even after the numbers have been masked. At the Japan Monkey Centre, a zoo next door to the Primate Research Institute, visitors can take their turn at the same test, but they are no match for Ayumu. Are chimpanzees smarter than us?
