In the present chapter we review a set of studies conducted in our laboratory that provide evidence on the continuity between prelinguistic and linguistic development, and on the interplay between the gestural and the vocal modalities in both typically developing children and in children with Down and Williams syndromes, whose development proceeds in atypical conditions. Corballis (2002) evolutionary views on a slow transition from gesture to vocal language appear to be supported by our developmental data, as this transition, and the interdependency between gesture and speech, seem still evident in childrens communicative and linguistic development. As observed by Deacon, it is of course unlikely that language development recapitulates language evolution in most respects (because neither immature brains nor children's partial mapping of adult modern languages are comparable to mature brains and adult languages of any ancestor) (Deacon, 1997 p. 354), but we can gain useful insights into the organization and evolution of both language and gesture by investigating the interplay between these modalities in the communication and language systems of children with typical and atypical development.
