I misread this as AI initially ...

The only art-centric monkey I knew was Koko, the female gorilla.

Here she draws some things:

Smartest monkey I ever saw was Kanzi though:

I think it is only a question and matter of time before the prison systems for monkeys may have to be reconsidered completely. Of course even smarter monkeys than Kanzi won't reach human brain functions, but they are also very convincingly extremely clever and can adapt. Numerous videos where monkeys handle (!) smartphones show this already and this is just the beginning. Like, in the movie Planet of the Apes. Just long-term in smaller steps.
