The evolution of human language is a complex process that likely began over 100,000 years ago. Early humans used basic **gestures** and **vocal sounds** to communicate, evolving alongside brain development. As social groups grew, the need for more complex communication led to the development of structured **syntax** and **grammar**. Over time, language diversified into distinct families, such as **Indo-European** and **Sino-Tibetan**, due to migration and isolation of populations. Language evolution is driven by cognitive, cultural, and environmental factors, allowing humans to share ideas, pass down knowledge, and form complex societies. Today, there are over 7,000 spoken languages worldwide.
