Further issues in neurolinguistic preconditions

Abstract
This response to continuing commentary addresses brain-hand relationships inCebus apella(as introduced in West-ergaard's commentary), the evolutionary and acquisition parallels between music and language (suggested by Lynch), and the potential behavioral linguistic consequences of the evolutionary neurobiology inAustralopithecus africanusandHomo habilis(discussed by Tobias). Finally, we reiterate the importance of well informed, multidisciplinary approaches to the study of the emergence of human species-specific cognition, especially linguistic capacity.
