Today we are sharing an episode from one of our newest series -- A Show About Animals. This season, we tell the strange and wonderful story of the wildly famous Koko the “talking” Gorilla. 

In the early 1970s, a grad student named Penny Patterson set out to investigate a big question: is language unique to humans? So she begins an ambitious experiment -- with the help of a young gorilla named Koko. Pretty soon, Penny says Koko is learning sign language. But, of course, that’s not the whole story.
