Few topics of scientific enquiry have attracted more attention in the last decade than the origin and evolution of language. Few have offered an equivalent intellectual challenge for interdisciplinary collaborations between linguistics, cognitive science, prehistoric archaeology, palaeoanthropology, genetics, neurophysiology, computer science and robotics. The contributions presented in this volume reflect the multiplicity of interests and research strategy used to tackle this complex issue, summarize new relevant data and emerging theories, provide an updated view of this interdisciplinary venture, and, when possible, seek a future in this broad field of study.
