Study Notes
Development of Human Speech
- Human brain size increased rapidly around 1.5 million years ago, leading to changes in brain structure and the development of the frontal lobe, responsible for language production.
- The vocal tract also evolved during this period, enabling humans to produce speech sounds.
Impact of Language on Human Evolution
- Language allowed humans to spread globally and engage in three crucial activities: thinking and planning for the future and passing on knowledge.
- Language "changed the human story profoundly", according to Dr. Mithen.
Timeline of Language Development
- Dr. Mithen suggests that basic language emerged around 1.6 million years ago, eight times earlier than previously thought (200,000 years ago).
- The first human language likely developed in eastern or southern Africa.
Significance of Language
- The ability to speak was a key factor in human physical and cultural evolution, according to Dr. Mithen.
Explore Dr. Mithen's theory on human speech development as explained in his book, 'The Language Puzzle'. Learn how the increase in brain size over 1.5 million years ago led to the development of the frontal lobe, crucial for producing language, and the evolution of the vocal tract for speech production.
