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.  You can listen to our weekly series, A Show About Animals, in all the places you get your podcasts.  A Show About Animals is hosted and reported by Arielle Duhaime-Ross and produced by Julia Nutter and Pete Lang-Stanton.
