Bird Brains Follow the Beat

ScienceDaily (Feb. 24, 2012) — By training birds to 'get rhythm', scientists uncover evidence that our capacity to move in time with music may be connected with our ability to learn speech.

Even though typical dance-floor activity might suggest otherwise, humans generally demonstrate a remarkable capacity to synchronize their body movements in response to auditory stimuli. But is this ability to move in time to musical rhythm a uniquely human trait?
Some animals are capable of vocal learning, changing the sounds they make in response to those they hear from other members of their species. Scientists have hypothesized that such behavior may be associated with the capacity for so-called 'rhythmic synchronization'. "Motor control of vocal organs is naturally important in vocal learning," says Yoshimasa Seki of the RIKEN Brain Science Institute in Wako. "Once auditory-motor coordination in the vocal control system has been established, a similar auditory-motor transformation system for other body parts might be derived from that."
