Japanese researchers pitted young chimps against human adults in two tests of short-term memory, and overall, the chimps won.

That challenges the belief of many people, including many scientists, that "humans are superior to chimpanzees in all cognitive functions," said researcher Tetsuro Matsuzawa of Kyoto University.

"No one can imagine that chimpanzees — young chimpanzees at the age of 5 — have a better performance in a memory task than humans," he said in a statement.
