If you RTWT -- nothing much. It's a very straightforward process of individual and family contact, and the changing of generations (rather faster in monkeys than humans; they are mature by about 4-5 yrs old.) Communication and interaction and opinion-change and so on is mightily facilitated among humans by language, and now by digital memory and sharing.Or the 100th monkey. Google that, interesting what happens when the 100th monkey copies a behavior.

No monkeys required. Or "morphogenic fields".
