Traditionally, the main approach to understand the evolution of vocal communication has been to describe the differences in the adult brain using a comparative approach. In our view, a more complete picture emerges when we view the nervous system as a part of the ever-changing system of brain, body, and environment. Using marmoset monkeys, who naturally exhibit vocal behaviors similar to our own, we're investigating how their communication emerges through the dynamic interactions between neural systems, the body, post-natal experience and social context. I will present postnatal data which will (1) show the role of body and environmental constraints on vocal development and (2) suggest that marmoset infants, like their human counterparts, use parental feedback from to facilitate the maturation of their vocalizations. Overall, these data offer an alternative view regarding the origins of human vocal communication.
