Monkey experiments offer clues on origin of language

14 Sept 17:01 Key points summarised by AI
  • Green and vervet monkeys, despite 3.5 million years of evolutionary divergence, share a hard-wired vocabulary for danger, highlighting an innate basis for communication.
  • Vervet monkeys use distinct calls for specific predators like leopards, snakes, and eagles, prompting precise, adaptive responses from their group.
  • Green monkeys, when exposed to a drone (a novel aerial threat), produced an alarm call strikingly similar to the vervet eagle call, suggesting a conserved, innate response to general aerial dangers.
  • This research indicates that a foundational, innate vocal repertoire, akin to pre-verbal human infant sounds, exists in primates, offering insights into the evolutionary building blocks of language.
