Using GPS, two primatologists followed 15 chimpanzees for 217 days, and determined that the apes were 'using a mental map built around geometric coordinates.' They're not just identifying landmarks in their surroundings, and in fact, even when swinging through trees, the chimps planned out their route several trees in advance. Here's the paper in the journal Animal Behavior."
The most difficult thing in the world is to know how to do a thing and to
watch someone else doing it wrong, without commenting.
