I fully expect Captain Disillusion to completely deconstruct this video in the coming days. There's no way it isn't VFX. The chimp naturally swipes through instagram, ending on a video of when it first met the owner? Please. It's a viral stunt, nothing more.
Chimps can recognize their own image in a mirror. To me, that makes it seem at least plausible that they could understand the level of abstraction necessary to scroll through a list of pictures with a touch screen.
If the chimp was taught how to publish content (as opposed to just consuming), I wonder if it would do so of its own accord.
Great, now we're getting Chips addicted to social media!
Chimpanzee is capable of learning by imitation and cultural learning. So technically if you show a few of them how to use Instagram, it will spread quickly.
What is more spectacular about this video is the fact that the Chimpanzee is not doing it for a reward!
