Roc Morin writes: One of the first words that Koko used to describe herself was Queen. The gorilla was only a few years old when she first made the gesture — sweeping a paw diagonally across her chest as if tracing a royal sash.
“It was a sign we almost never used!” Koko’s head-caretaker Francine Patterson laughed. “Koko understands that she’s special because of all the attention she’s had from professors, and caregivers, and the media.”
The cause of the primate’s celebrity is her extraordinary aptitude for language. Over the past 43 years, since Patterson began teaching Koko at the age of 1, the gorilla has learned more than 1,000 words of modified American Sign Language—a vocabulary comparable to that of a 3-year-old human child. While there have been many attempts to teach human languages to animals, none have been more successful than Patterson’s achievement with Koko.
If Koko is a queen, then her kingdom is a sprawling research facility in the mountains outside Santa Cruz, California. It was there, under a canopy of stately redwoods, that I met research-assistant Lisa Holliday.
“You came on a good day,” Holliday smiled. “Koko’s in a good mood. She was playing the spoon game all morning! That’s when she takes the spoon and runs off with it so you can’t give her another bite. She’s an active girl. She’s always got her dolls, and in the afternoon, her kittens — or as we call them, her kids.”
It was a winding stroll up a sun-spangled trail toward the cabin where Patterson was busy preparing a lunch of diced apples and nuts for Koko. The gorilla’s two kitten playmates romped in a crate by her feet. We would go deliver the meal together shortly, but first I had some questions for the 68-year-old researcher. I wanted to understand more about her famous charge and the rest of our closest living relatives. [Continue reading…]
