A prospect for evolutionary adequacy: merge and the evolution and development of human language

Biolinguistic minimalism seeks a deeper explanation of the design, develop-ment and evolution of human language by reducing its core domain to the bare minimum including the set-formation operation Merge. In an attempt to open an avenue of research that may lead to an evolutionarily adequate theory of language, this article makes the following proposals: (i) Merge is the elementary combinatorial device that requires no more decomposition; (ii) the precursor to Merge may be found in the uniquely human capacity for hierarchical object manipulation; (iii) the uniqueness of the human lexicon may also be captured in terms of Merge. Empirical validations of these pro-posals should constitute one major topic for the biolinguistic program
