The texts gathered in this volume reflect some of the breadth of the rapidly developing research area of the evolution of language.  The articles reflect many of the focal threads of this research field and, taken in toto, can be treated as a record of some the current controversies in language evolution studies. There is a growing interest among linguists to incorporate evolutionary concerns in their modes of language analysis - in the volume, the linguistic or linguistically oriented contributions focus on such areas of language description as articulatory phonetics (Bart de Boer), syntax and the origins of grammar (Eugenia Casielles and Ljiljana Progovac, Ljiljana Progovac, Junichi Toyota), and broadly understood pragmatics (Przemysław Żywiczyński). These are followed by papers primarily centring on evolutionary concerns, related to research in cognitive psychology and paleoanthropology (Rodrigo de Sá-Saraiva and Ana Isabel de Sá-Saraiva), sound symbolism (Juan Carlos Moreno Cabrera) and memetics (Luke McCrohon). The volume is complemented by more theoretical works, employing the methods of analytical philosophy to clarify fundamental conceptual issues in the evolution of language research (Szymon Wróbel, Sławomir Wacewicz). Together with Lluís Barceló-Coblijn's comprehensive study on the evolution of recursion, those three texts reflect on the problems posed by Hauser, Chomsky and Fitch (2002) in their seminal article "The faculty of language: What is it, who has it, and how did it evolve?".
