In my experience, this could possibly make sense, in moderation, over 10s of thousands of years.

Seems like it would make more sense on a short-term scale. One good trip for an ape might be enough to give him the idea for symbolic representation, either written or spoken, that had never occurred to him before. While tripping, the idea that the sound "arrrggh" represents a threat, for example, could be the basis for spoken language that is then built on over time. But what do I know, I'm just a cave man who has never taken magic mushrooms.
