I know that chimpanzees(and other apes) can learn sign language. But the cool thing is that they can make simple sentances and even teach other chimps sign language after they learn it.
So my question is, if we teach alot of chimps sign language, and other skills, like how to make simple tools, and then if we released them back into the wild, could they teach more chimps and then evenutally a whole area of a chimp population these skills. And then they could pass it down from generation to generation. Is his Theoretically possible?
