THE FIRST WORD

Linguist and popular-science journalist Kenneally lucidly explains how scientists explore language.

It never hurts to begin with a genius, so the author opens by declaring, “the story of language evolution studies is unavoidably the story of the intellectual reign of Noam Chomsky.” Before Chomsky, linguists searched for new languages, wrote down vocabulary and grammar and compared them to other languages. They never addressed questions about the origin of language because conventional wisdom declared such questions could not be answered. Sixty years ago, Chomsky pointed out that infants learn to talk merely by interacting with those around them for a few years. Since conversation contains too little information to provide rules for this incredibly complex skill, humans must be born with the unique ability to learn to speak. This assertion galvanized a generation of researchers who turned their attention to the roots of language. Since Chomsky asserted that language is a uniquely human phenomenon, he doubted evolution played a role in its origin. So great was his influence that scientists have only recently overcome their inhibitions and turned up fascinating evidence to the contrary. Readers will blink as the author describes studies demonstrating that animals use language and can be taught more. Early, highly publicized experiments with apes gave the field a bad reputation because the animals seemed to be responding to trainers’ cues, but careful studies make it clear that many animals can employ syntax and vocabulary at the level of a three-year-old human. Despite our vastly superior language abilities, researchers have yet to find any speech areas in the human brain that are not present elsewhere in the animal kingdom. Kenneally’s book features a steady stream of brilliant, opinionated people expressing ideas that often contradict those of other brilliant people, but she channels this flood of frequently technical arguments into a comprehensible and stimulating narrative.

Lively portrait of a fascinating new scientific field.
