The FOXP2 gene is present in homo sapiens today and allows us to make the fine lip and tongue movements needed for intelligible speech. The speech-friendly variation of the gene took hold in human beings around 150,000 years ago. Our primate relatives have a different variation of the gene, and this is thought to be one of the reasons humans are the only primates capable of developing fully-formed complex language. What adaptive benefits has language provided for homo sapiens?
