Researchers have made a significant discovery by inserting a human-specific gene, NOVA1, into mice, leading to notable changes in their vocal communication. The modified mice produced higher-pitched sounds and a diverse range of vocal patterns. This suggests that subtle genetic variations, like the one in NOVA1, could have significantly influenced the development of human language and communication abilities during evolution.
