Penny and Koko: Reflections on Motherhood (2018)

Penny has been like a mother to Koko, from the time she began caring for her as a baby gorilla, through years of communication-based research and relationship building, to the present, where Koko now exhibits many of the same maternal qualities to her kittens, great ape dolls and human caregivers. There is so much to learn from Koko and other gorillas, as we begin to make basic (sign-language) communication skills accessible to all captive gorillas, and Koko extends her (motherly) love to the next generation.
