This book looks at how the human brain got the capacity for language and how language then evolved. Its four parts are concerned with different views on the emergence of language, with what language is, how it evolved in the human brain, and finally how this process led to the properties of language. Part I considers the main approaches to the subject and how far language evolved culturally or genetically. Part II argues that language is a system of signs and considers how these elements first came together in the brain. Part III examines the evidence for brain mechanisms to allow the formation of signs. Part IV shows how the book's explanation of language origins and evolution is not only consistent with the complex properties of languages but provides the basis for a theory of syntax that offers insights into the learnability of language and to the nature of constructions that have defied decades of linguistic analysis, including including subject-verb inversion in questions, existential constructions, and long-distance dependencies. Denis Bouchard's outstandingly original account will interest linguists of all persuasions as well as cognitive scientists and others interested in the evolution of language.

O. PRELIMINARY REMARKS Initial drafts of the papers in this collection were presented in a con ference entitled 'Views on Phrase Structure', held at the University of Florida, Gainesville, in March, 1989. Eleven of the twenty-three partici pants in the conference were able to contribute to this volume. The purpose of the conference was to explore theories of phrase structure in their relation to other subsystems of grammar and/or systems of nonlinguistic knowledge. Some of the grammatical subsystems which the authors consider are theta-theory, movement, Case, and binding; a number of papers address how the conceptual system and/or aspects of language use may interact. Unifying the various approaches and perspectives is an attempt to furnish hypotheses concerning prin ciples of phrase structure with some sort of independent justification. 1. PHRASE STRUCTURE THEORY: A BRIEF HISTORY A basic outline for a theory of phrase structure theory is accepted by all of the authors here; it is known as 'X-bar theory'. The concepts of X-bar theory are expressed in some form by a number of pre-generative linguists. For example, Bloomfield (1933) contrasted endocentric struc tures such as noun phrases and verb phrases with those he considered exocentric, e. g. prepositional phrases and clauses. Jespersen (1933), while presenting a functional system of description (in terms of 'ranks', where rank one is 'nominal', for example), clarified the relations among the head of a phrase, its modifier, and a phrase which modifies the modifier."

The architecture of the human language faculty has been one of the main foci of the linguistic research of the last half century. This branch of linguistics, broadly known as Generative Grammar, is concerned with the formulation of explanatory formal accounts of linguistic phenomena with the ulterior goal of gaining insight into the properties of the 'language organ'. The series comprises high quality monographs and collected volumes that address such issues. The topics in this series range from phonology to semantics, from syntax to information structure, from mathematical linguistics to studies of the lexicon.
