Young chimps top adult humans in numerical memory
... Chimpanzee memory has been extensively studied, the researchers said. The general assumption is that, as with many other cognitive functions, it is inferior
to that of humans. However, some data have suggested that, in some circumstances, chimpanzee memory may indeed be superior to human memory.
