Koko is perhaps the best known gorilla in the world because of her sign language and artistic abilities, her relationships with kittens, and a considerable amount of worldwide media since she was a baby. However, Koko is not the only gorilla that has mastered sign language (and art) — she has grown up with several equally interesting (and intelligent) friends. In this section, we introduce you to Koko and her extended family at The Gorilla Foundation — Michael and Ndume — and contrast these “enculturated” gorillas with gorillas around the world.
