title: The sound of one hand clapping: overdetermination and the pansensory nature of communication.
abstract: Two substantive issues are relevant to discussions of the evolution of acoustic communication and merit further consideration here. The first is the importance of communicative ontogeny and the impact of the proximal social environment on the early development of communication and language. The second is the emerging evidence for a number of non-linguistic roles of FOXP2 and its orthologs.
