Koko

Koko is arguably the most significant animal to date in recent years. She was “the gorilla that understands 2,000 words and can sign 1,000 of them.” She made an everlasting impact on the scientific community and humanity. Her life led to new revelations about animal empathy and communication.

Hanabi-Ko “Koko”

Koko’s full name was Hanabi-ko which is Japanese for “fireworks child.” Her name comes from her birthdate which is actually on American independence day: July 4. She was born in 1971 and since a young age she was called “Koko.”

Koko Meets Penny Patterson

Koko was born on July 4th at the San Fransisco Zoo. When she was 1 she was loaned to a doctoral candidate in developmental psychology at Stanford University named Francine “Penny” Patterson. Penny Patterson was developing an interesting argument that animals were a little more like humans than everyone else thought.

Animals Are Like Humans?

Over the course of human history, both scientists and philosophers have argued about the linguistic abilities and emotional intelligence of animals. Some believe animals have emotions, inner thoughts, and communication abilities similar to humans. Others believe there is no comparison, and humans are unique because they are able to use a working language to communicate and express themselves.

Sign Language

Penny Patterson wanted to examine this and see if animals could express themselves using language. She first began working with Koko in 1972. Her first idea was to try to teach Koko American Sign Language or ASL.

Learning American Sign Language

Koko was only on loan at first to Penny Patterson for a short study on interspecies communication. After successfully teaching Koko some American Sign Language, she consulted fellow researcher, Ronald Cohn. The two decided to start a non-profit organization which aimed to officially adopt Koko. They co-founded The Gorilla Foundation to officially support the adoption and research efforts about the amazing gorilla.

The team of Patterson and Cohn were successful! Together they raised $12,000 to officially adopt Koko. After the adoption, they decided to move Koko to the Santa Cruz Mountains in 1979 for further research.

A Great Leap Forward

Let’s not get ahead of ourselves. The fact Penny Patterson was able to even teach Koko some American Sign Language is remarkable and unprecedented! Just by achieving this, Patterson helped prove apes can have linguistic abilities similar to young children. A researcher at York University named Anne Russon stated that teaching Koko sign language, as opposed to solely verbal communication, was a “great leap forward.”

Linguistically Gifted

Koko was already very clearly on her way to becoming the most intelligent ape in history! With the help of Patterson, she learned more than 1,000 words in sign language and came to understand over 2,000 words spoken to her in English! Amazing!

Verbal And Communication Abilities

Koko’s language acquisition was a process. To start, Koko learned simple nouns like toy, tree, apple, and cookie. She then learned hundreds of simple nouns impressing everyone. She progressed to learning and using verbs. Researchers believe she developed mood and emotional communication abilities similar to humans!

Koko Understood Meaning Behind Words

Koko was displaying evidence that she had the ability to communicate. She began to build short sentences. One example is she said to Patterson, “You key there me cookie.” She was requesting Patterson to open the cabinet and bring her a snack. She was not only communicating, but she was proving that she understood the meaning behind her communication!

In a recent interview, Penny Patterson stated, “She taught me more than I taught her, for sure.” She continued, “She had opportunities to show her brilliance and that’s what we saw. We saw a person, really. She had all the attributes of a person and then some.”

Super Smart Gorilla

Moreover, Barbara King, a professor of anthropology at the College of William and Mary stated, “Because she was smart enough to comprehend and use aspects of our language, Koko could show us what all great apes are capable of: reasoning about their world, and loving and grieving the other beings to whom they become attached.”

Penny Patterson stated in a recent interview Koko looked “peaceful” when she died, but researchers were still understanding the cause of death. In an interview with ABC news, Patterson said, “We’re still trying to understand what the cause was.” She went on to say, “Many gorillas have a heart condition, cardiomyopathy, and she had it, but it was apparently a mild case and was being treated for that. That’s one possibility.”
