The Bonobo Ape

Paper Summary:

This paper is in two parts. The first part reviews and summarizes past work in ape language research, including the Gardners' work with the chimp Washoe, Francine Patterson's work with Koko the gorilla, Lyn Miles's work with Chantek the orangutan and Sue Savage-Rumbaugh's work with bonobos and chimps. The second part is a proposal for an experiment to teach American Sign Language to a group of bonobos and then use these communicative abilities to test their memory and planning abilities. It includes descriptions of bonobo behavior in the wild and captivity, an argument for gestural language as the first human language and a description of the means of teaching and testing the bonobos in the proposed experiment. The paper includes a table and illustrations.

From the Paper:

"During the Oligocene epoch of the Tertiary period, a small monkey-like creature lived in the rainforest trees in central Africa. About thirty million years ago, this primate ancestor diverged into two distinct species; one would father the line of Old World monkeys, including baboons and macaques. The other would become the predecessor of modern apes and humans. Around twenty-two million years ago gibbons split away from that line and formed a branch known as the lesser apes. Six or seven million years later, orangutans too diverged from the ape lineage and migrated to the Asian islands of Sumatra and Borneo, where they remained highly arboreal. Another eight or nine million years passed, during which this ape line began to spend more time on the ground, and gorillas split off to become their own species. Two million years more went by, bringing us to the Pliocene epoch, which began about five million years ago. It was at this crucial point in evolutionary history that our ancestors and the ancestors of modern chimpanzees and bonobos took different paths, the former leading to bipedality, ground-based life, and hominization, the latter eventually splitting into two more distinct species about three million years ago, both of whom would remain remarkably similar to us physically, behaviorally, emotionally, and intellectually (Goodall, Hook, Leakey, Linden 1992)."
