This quote by our dear GingerCoffee had inspired me to make this thread. Can a gorilla like Koko know as many signs as claimed? I've always heard that the smartest ape is as intelligent as our human toddlers, so with that in mind, Koko is as smart as a deaf toddler. To me, it's not unfeasible that Koko herself would know that many signs. Thoughts? I'll post mine later, but I'm looking forward to what Ginger has to say, and what you all have to say as well.
