The change in gene sequences that led to a change in the way the brain processes speech is believed to have occurred between 1 and 6 million years ago. This timeframe aligns with the period during which humans and our closest evolutionary relatives were diverging, suggesting that changes in these genes could have been crucial for the development of speech and language capabilities unique to humans.
