Last week I watched "Rise of the Planet of the Apes," a new film about superintelligent chimps that bust out of captivity and rampage across San Francisco in a bid for freedom.

After that — of which more in a moment — I came across a new paper by Kyoto University's famed primatologist, Tetsuro Matsuzawa.

Matsuzawa's work is always fascinating. He has been working on the Ai project at Kyoto since 1978, a study on the memory and language ability of a female chimp named Ai. The project is one of the world's longest-running lab-based inquiries into chimpanzee intelligence.
