Geertz says:
"That any (living or extinct) infra-hominid primate can be said to possess true culture - in the narrowed sense of "an ordered system of meaning and symbols...in terms of which individuals define their worlds, express their feelings and make their judgments" - is of course extremely doubtful. But monkeys and apes are through-and-through social creatures as to be able to be unable to achieve emotional maturity in isolation, to acquire a great many of their most important perfomance capacities through imitative learning (monkey see; monkey do -CB) and to develop distinctive intraspecifically variable collective social traditions which are transmitted as non-biological heritage from generation to generation is now well established."
