KANZI THE BONOBO has fascinated humans after learning to understand English and to communicate his thoughts and feelings through pointing to a choice of hundreds upon hundreds of symbols.

Born in 1980, Kanzi has spend his life learning language with primatologist Sue Savage-Rumbaugh, a lead scientist at the Great Ape Trust of Iowa. Kanzi can understand Rumbagh when she speaks but – because it is physically impossible for a primate – he cannot speak back.

Instead, Kanzi can communicate by pointing to various symbols on lexigram keyboards.

Savage-Rumbaugh believes that all it takes for an ape to acquire an understanding of language is spoken language,  repetition, non-verbal cues and attention-directing manuevuers – the same way that we speak to human children.

Watch Kanzi interact with Savage-Rumbaugh as she speaks novel sentences to him – note Kanzi would not able to lip read, as Savage-Rumbaugh’s face is covered, and so must rely only on hearing the language.

In the video below, watch Kanzi communicate through his lexigram keyboards.
