language bioprogram theory

The language bioprogram theory or language bioprogram hypothesis (LBH) is a theory arguing that the structural similarities between different creole languages cannot be solely attributed to their superstrate and substrate languages. As articulated mostly by Derek Bickerton, creolization occurs when the linguistic exposure of children in a community consists solely of a highly unstructured pidgin; these children use their innate language capacity to transform the pidgin, which characteristically has high syntactic variability, into a language with a highly structured grammar. As this capacity is universal, the grammars of these new languages have many similarities.
