apes have a very much larger short memory than humans and can use these informations also very much faster. also everything in orientation in a 3d room is much better and faster. they can move about 50 meters in a wood and can remember everything to go there blindfolded.
Do you have some research that points to apes having a 'larger' short term memory than humans?
they ate monkey brains in "Indiana Jones and the Temple of Doom"
perhaps eating monkey brains wills make you smarter
They did so in the film series Faces Of Death too. Except it was REAL monkey brains straight from the skulls.
