Are Darwinian mechanisms of natural selection and sexual selection enough to explain the origins of our verbal abilities? Is it imperative to stick to them in order to develop a true biologistic research program on language? The main theses that run through this book respond negatively to both questions and suggest that Chomskyan minimalism offers adequate bases to face the study of language as an aspect of the natural world. Biology must certainly inspire the scientific understanding of language, but the study of language may also help to broaden our understanding of the principles that govern the organic world.
