Kanzi (born
October 23,
1980), a
bonobo, is one of the most most famous and accomplished linguistic
apes, in research led by
E. Sue Savage-Rumbaugh.
Born to Lorel and Bosandjo at Yerkes field station at
Georgia State University, Kanzi was stolen and adopted shortly after birth by a more dominant female, Matata. As an infant, Kanzi accompanied his mother to sessions where she was taught language through keyboard
lexigrams, but displayed 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 use language at all. Within little time, Kanzi had mastered the ten that researchers had been struggling to teach his adoptive mother, and has since learned more than two hundred more. Also notable is Kanzi's ability to understand spoken language and associate it with lexigrams, Kanzi's ability to understand simple grammatical sentences, and possibly his invention of novel vocalized words.
Kanzi is also a far more accomplished tool user and inventor than practically all other apes. (See September 1994 issue of Discover article, "Ape at the Brink")
