Book: Functional Dimensions of Ape-Human Discourse
Chapter: The evolutionary dimension: the thin edge of the wedge – grammar and discourse in the evolution of language
Blurb:
This chapter examines three snapshots taken from comprehensive studies with large amounts of data: evidence for proto-metafunctional differentiation in monkeys, evidence in a human child for the transition from indexical call systems to ideationally and interpersonally differentiated symbolic lexicogrammar and evidence in a bonobo-human interaction for the interpretation of ideationally and interpersonally differentiated human lexicogrammar.
