So easy a monkey could do it.

Most of us humans have never piloted spacecraft or learned sign language. Most of us probably suck at Memory too. Not these chimps. Our evolutionary cousins at The Primate Research Institute of Kyoto have learned to outperform humans in tasks of numerical sequence and memory. The study suggests that chimpanzees may have much higher cognitive abilities than previously estimated, even by many modern biologists. The study also suggests that placing treat dispensers in arcade games is good for science.
