Scientists at UCLA have identified around 2,000 genes in zebrafinches linked to singing - more than 1,500 than were previously known about. All 2,000 show changes in activity levels when birds sing, and a number of them are also found in humans, making the researchers think they may also play a role in human speech and speech disorders such as autism.
