, Kanzi was stolen and adopted shortly after birth by a more dominant female, Matata. As an infant, Kanzi accompanied Matata to sessions where she was taught language through keyboard lexigrams, but showed little interest in the lessons.

It was a great surprise to researchers then when one day, while Matata was away, Kanzi began competently using the lexigrams, becoming not only the first observed ape to have learned aspects of language naturalistically rather than through direct training, but also the first observed bonobo to appear to use some elements of language at all. Within a short time, Kanzi had mastered the ten words that researchers had been struggling to teach his adoptive mother, and he has since learned more than two hundred more. When he hears a spoken word (through headphones, to filter out nonverbal clues), he points to the correct lexigram.

 of the resident community of Bonobos. His mother, Matata, is the chief leader (in the matriachal society of bonobos, a male's position is primarily determined by the position of the females he is related to). According to the Smithsonian magazine, Kanzi "has the mien of an aging patriarch - he's balding and paunchy with serious, deep-set eyes." This description is confirmed by a full-page color photograph of Kanzi in the March 2008 National Geographic, and a full-page black-and white photograph in Time magazine.

Examples of Kanzi's behavior

The following are highly suggestive anecdotes, not experimental demonstrations. As with all anecdotal accounts, the strength of conclusions drawn must be limited, as compared with well-controlled experimental evidence.
  • In an outing in the Georgia

    s" and "fire." Susan Savage-Rumbaugh said in an interview that, "Given matches and marshmallows, Kanzi snapped twigs for a fire, lit them with the matches and toasted the marshmallows on a stick."

  • Paul Raffaele, at Savage-Rumbaugh's request, performed a Maori War Dance

     for the Bonobos. This dance includes thigh-slapping, chest-thumping, and hollering. Almost all the bonobos present interpreted this as an aggressive display, and reacted with loud screams, tooth-baring, and pounding the walls and floor. All but Kanzi, who remained perfectly calm; he then communicated with Savage-Rumbaugh using bonobo vocalizations; Savage-Rumbaugh understood these vocalizations, and said to Raffaele, "he'd like you to do it again just for him, in a room out back, so the others won't get upset." Later, a private performance in another room was successfully, peacefully, and happily carried out.

  • Sue Savage-Rumbaugh has observed Kanzi in communication to his sister. In this experiment, Kanzi was kept in a separate room of the Great Ape Project and shown some yogurt. Kanzi made some vocalizations which his sister could hear; his sister, Panbanisha

    , who could not see the yogurt, then pointed to the lexigram for yogurt, suggesting those vocalizations may have meaning.

  • Kanzi's accomplishments also include tool use and tool crafting. Kanzi is an accomplished stone tool maker and can flake Oldowan style cutting knives. He learned this skill from Dr. Nick Toth, who is an anthropologist with the Stone Age Institute

Language

s.

Kanzi cannot speak vocally in a manner that is comprehensible to most humans as Bonobo chimps have different vocal tracts from humans, which makes them incapable of reproducing most of the vocal sounds humans make. At the same time, it was noticed that every time Kanzi communicated with humans with specially designed graphic symbols, he also produced some vocalization. It was later found out that Kanzi was actually producing the articulate equivalent of the symbols he was indicating, or, in other words, he was "saying" (articulating) these words, although in a very high pitch and with distortions.
