Hanabiko, nicknamed "Koko" (July 4, 1971 – June 19, 2018) was a female western lowland gorilla born in the San Francisco Zoo[2] and cross-fostered by Francine Patterson for use in ape language experiments. Koko gained public attention as the subject of two National Geographic cover stories and, in 1980, the best-selling children's picture book, Koko's Kitten. Koko became the world's most famous representative of her critically endangered species.
Koko's communication skills were hotly debated.[3][4][5] Koko used many signs adapted from American Sign Language, but the scientific consensus to date remains that she did not demonstrate the syntax or grammar required of true language. Patterson was widely criticized for misrepresenting Koko's skills, and, in the 1990s, for her care of Koko and Gorilla Foundation staff.
Despite such controversies, Koko's story changed the public image of gorillas, previously assumed to be brainless and violent.[6] As Science noted in its obituary, Koko "helped transform how the human world viewed animal emotion—and intelligence."[7]
Born July 4, 1971, Koko was born Hanabi-ko, Japanese for "fireworks child," at the San Francisco Zoo.
