Is language somehow innate in the structure of the human brain, or is it completely learned? This debate is still at the heart of linguistics, especially as it intersects with psychology and cognitive science. In collecting papers which discuss the evidence and arguments regarding this difficult question, The Inheritance and Innateness of Grammars considers cases ranging from infants who are just beginning to learn the properties of a native language to language-impaired adults who will never learn one. These studies show (...) that, while precursors of language exist in other creatures, the abilities necessary for constructing full-fledged grammars are part of the biological endowment of human beings. The essays that comprise this volume test the range and specificity of that endowment, while also contributing to our understanding of the intricate and complex relationship between language and biology.

Müller argues that general cognitive skills and linguistic skills are not necessarily independent. However, cross-linguistic evidence from an inherited specific language disorder affecting productive rules suggests significant degrees of modularity, innateness, and universality of language. Confident claims about the overall nature of such a complex system still await more interdisciplinary research.
