A gene implicated in human language affects song learning in songbirds

Do special “human” genes provide the biological substrate for uniquely human traits, like language" Genetic aberrations of the human FoxP2 gene impair speech production and comprehension, yet the relative contributions of FoxP2 to brain development and function are unknown. Songbirds are a useful model to address this because, like human youngsters, they learn to vocalize by imitating the sounds of their elders.
