Chimpanzees have an extraordinary photographic memory that is far superior to ours, research suggests.
Young chimps outperformed university students in memory tests devised by Japanese scientists. The tasks involved remembering the location of numbers on a screen, and correctly recalling the sequence.
"There are still many people, including many biologists, who believe that humans are superior to chimpanzees in all cognitive functions," said lead researcher Tetsuro Matsuzawa of Kyoto University.
"Here we show for the first time that young chimpanzees have an extraordinary working memory capability for numerical recollection - better than that of human adults tested in the same apparatus, following the same procedure."
