Many scientists believe that the human brain’s capacity for language is innate, that the brain is actually “hard-wired” for this higher-level functionality. But theoretical neurobiologist Changizi (director of human cognition, 2AI Labs; The Vision Revolution) brilliantly challenges this view, claiming that language (and music) are neither innate nor instinctual to the brain but evolved culturally to take advantage of what the most ancient aspect of our brain does best: process the sounds of nature. By “sounds of nature,” Changizi does not mean birds chirping or rain falling. His provocative theory is based on the identification of striking similarities between the phoneme level of language and the elemental auditory properties of solid objects and, in the case of music, similarities between the sounds of human movement and the basic elements of music.
Verdict: Although the book is written in a witty, informal style, the science underpinning this theoretical argument (acoustics, phonology, physics) could be somewhat intimidating to the nonspecialist. Still, it will certainly intrigue evolutionary biologists, linguists, and cultural anthropologists and is strongly recommended for libraries that have Changizi’s previous book.
