We all know about Koko, the gorilla that learned sign language! Dan and Mauro go into what it took to teach Koko sign language, what kind of signs she learned, her pet cats (!!!!), her potential mates, and everything in between! It's actually an extremely heartwarming story that led to a deeper understanding of these misunderstood animals! If you'd like to learn more about the great work Koko's trainer, Penny Patterson continues to do you can visit The Gorilla Foundation's website - Thank you for listening!
