If another chimp doesn't know something, the lower ranking member that knows (e.g. where the banana is) will mislead and trick the higher ranker.
If theyre performing a task, both get grape, everyones happy, but when 1 gets a banana and the other gets grape (banana = better = gold = happy = yay!) then they will BOTH throw a temper tantrum till they get equal rewards!
Susposedly now, elephants and dolphins are equal intellect to us, and chimps are a superior race!
YEP, NATURE IS AWESOME.
BTW: dogs are stupid now as well. legit.
