Didn't Kubrick prophesy this? I'm thinking of the first act of the movie 2001: A Space Odyssey where one advanced primate learns how to use the femur of a tapir as a tool, then teaches the other primates in his tribe how to use bones as a weapon and how to walk upright (though we are not shown the teaching or knowledge transmission process).

No, since those are supposed to be the ancestors of humans.

But they're still primates, and therefore presumably more similar to chimpanzees than humans in terms of the ability to model and learn behaviour.

Humans are primates, but we don't presume we're more similar to chimpanzees than to humans.

Humans share 96 - 99% of our genome with chimpanzees. Presumably the difference between human sub-species would be even less.
