kKoko is a female gorilla who understands sign language.
According to her caregiver, Francine “Penny” Patterson, Koko has learnt over 1,000 signs of GSL (Gorilla Sign Language), taught by Penny herself. GSL, as Penny calls it, is a modified version of ASL (American Sign Language).
In addition, Koko can understand about 2,000 English words, despite the fact that her use of language is no better than that of a human child.
Nevertheless, it is outstanding that animals such as Koko can pick up languages to be able to communicate with us.
