Scientists Identify Gene Linked to Human Speech Evolution in Mice

Recent genetic research has unveiled significant insights into the evolution of human speech, centering on a gene called NOVA1, which underwent critical changes between 250,000 and 500,000 years ago in our ancestors. Scientists from Rockefeller University found that introducing the human variant of NOVA1 into mice resulted in more complex vocalizations, highlighting the gene's potential role in speech development. However, researchers caution that language evolution is likely influenced by many genes over millions of years, with NOVA1 being just one piece of the puzzle. The study not only sheds light on human linguistic capabilities but also offers potential avenues for addressing speech disorders. NOVA1 is unique to humans among mammals and has been linked to the brain's function in vocalization. This groundbreaking work suggests a genetic foundation for the linguistic abilities that distinguish humans from other species.
