For decades, linguists debated whether human language originated primarily from manual gestures or vocal calls. Proponents of the gestural theory pointed to the mirror neuron system in primates, which coordinates motor actions and imitation, suggesting language developed as gestures before transitioning to speech. Conversely, vocal theorists argued that early hominids relied on auditory signals for long-distance coordination in open environments. Recently, however, researchers have proposed a multimodal framework, suggesting that gestural and vocal communication evolved in tandem rather than sequentially. This integrated perspective reconciles the two traditional viewpoints, demonstrating that early communicative behaviors were likely composite systems of sound and movement.
Which choice best describes the overall structure of the text?
- AIt describes a widely accepted scientific theory, details a primary objection to that theory, and advocates for a complete replacement of the theory with a new hypothesis.
- BIt explains the functioning of primate mirror neurons, argues that gestures preceded speech in human history, and contrasts hominid coordination with modern communication.
- It presents a long-standing academic debate, outlines the respective arguments of two opposing viewpoints, and introduces a modern framework that integrates elements of both perspectives.Answer
- DIt traces the chronological evolution of human language, shows how vocal calls replaced manual gestures over time, and predicts how future human communication will change.
