Not a scientific observation, but the zoo I used to work at often planted medicinal plants in primate enclosures because they use them. I think this has been common in zoos for a long while.

The difference might be in primates in captivity learning from humans using tools around them all day every day. Primate see primate do trial and error.

One seen doing it spontaneously in nature might be more significant.

Nah, I've never been in the monkey house chewing ginger roots, they know this stuff, or work it out, not sure which really.
