From Scientific American
Kanzi, a male bonobo (an ape sometimes called a pygmy chimpanzee), has been under the care of language researcher Savage-Rumbaugh since infancy. Over a period of 18 years, he has learned to communicate his wants and to respond to spoken English by means of pictorial symbols called lexigrams. His communicative capability is about equal to that of a two-and-a-half-year-old human child. The first third of the book presents Savage-Rumbaugh's clear and entertaining account of Kanzi's upbringing. The remainder, largely written by the other two authors, is an argument in academic prose addressed primarily to critics who "insist that no ape has ever developed truly linguistic skills." The authors declare their "shared belief that the Kanzi research presents a serious and effective challenge not only to scientific thinking about the cognitive and communicational capacities of nonhuman primates, but also to received knowledge concerning the possession of those capacities by humans."
...enormously entertaining... -- The San Francisco Chronicle, Theodore Roszak
This book is worthwhile reading. It is provacative and entertaining. The issues it raises are fundamental. Are we different and above all other species? The authors scream 'NO'. You be the judge. -- Roger L. Mellgren, Applied Cognitive Psychology
