Theories of language evolution

Theories of language evolution explore how humans developed the ability to communicate using complex sounds and symbols. Some suggest language evolved gradually from gestures or calls used for survival, while others propose it emerged suddenly through genetic changes enabling symbolic thought. Others believe cultural and social interactions played key roles in shaping language over time. Overall, these theories aim to understand how spoken language, with grammar and vocabulary, became a fundamental part of human life from simpler pre-linguistic communication.
