Learn about the FOXP2 gene, which is related to speech and language, in this video from NOVA Wonders: What Are Animals Saying? Genetic analysis on a family with multiple generations of members who had trouble speaking led to the discovery of the FOXP2 gene. Neuroscientist Erich Jarvis describes how songbirds that have been genetically modified with a FOXP2 mutation cannot imitate sounds properly. Similarly, a male mouse with the FOXP2 mutation produces simpler songs compared to a normal mouse; this indicates that the gene appears to affect the ability to make complex sounds even in animals that are not vocal learners like songbirds and humans.
