Monkey speak: Macaques have the anatomy, not the brain, for human speech

(Princeton University) Researchers have found that monkeys known as macaques possess the vocal anatomy but not the brain circuitry to produce human speech. The findings suggest that human speech stems mainly from the unique evolution and construction of our brains, and is not linked to vocalization-related anatomical differences between humans and primates. Scientists have long debated if -- and to what extent -- differences between the human and primate vocal anatomy allow people to speak but not monkeys and apes.
