Meet Koko! Koko is 46-year-old Western Lowland Gorilla. She celebrates her birthday every year in company of her best friend Penny Paterson. Penny knows Koko since she was a little baby. To be more precise, from 1971. This unusual friendship started as a project.
Then 24-year-old graduate student of Stanford University, Penny met Koko at San Francisco Zoo. She knew that chimpanzees can learn ASL (American Sign Language), so, as a PhD project, she chose to teach gorilla sign language. That’s when she met a few months old baby gorilla. That’s when she met Koko. Nobody could’ve imagined that these two would become inseparable.
Incredibly yet Koko mastered even 400 signs as a baby. Each year her vocabulary grew. Today, Koko knows over 1.000 ALS signs and over 2.000 English language words. Apart from this success, even bigger one is relationship that Koko and Penny have.
Those who know Penny claim that Koko is like a child to her. They adore each other. Koko communicates with Penny about everything. About movies, food, presents and emotions.
Koko loves babies very much. Although there were attempts for Koko to become mother, that, sadly never happened. But, Koko doesn’t let that discourage her.
For this birthday Penny prepared a big surprise for Koko. What’s it about, see below:
What a surprise! Ms. Grey and Ms. Black will have very extraordinary new owner.
