After a long period where it has been conceived as iconoclastic and almost forbidden, the question of language origins is now at the centre of a rich debate, confronting acute proposals and original theories. Most importantly, the debate is nourished by a large set of experimental data from disciplines surrounding language. The editors of the present book have gathered researchers from various fields, with the common objective of taking as seriously as possible the search for continuities from non-human primate vocal and gestural communication systems to human speech and language, in a multidisciplinary perspective combining ethology, neuroscience, developmental psychology and linguistics, as well as computer science and robotics. New data and theoretical elaborations on the emergence of referential communication and language are debated here by some of the most creative scientists in the world.

The Gestural Communication of Apes and Monkeys is an intriguing compilation of naturalistic and experimental research conducted over the course of 20 years on gestural communication in primates, as well as a comparison to what is known about the vocal communication of nonhuman primates. The editors also make systematic comparisons to the gestural communication of prelinguistic and just-linguistic human children. An enlightening exploration unfolds into what may represent the starting point for the evolution of human communication and language. This especially significant read is organized into nine chapters that discuss: *the gestural repertoire of chimpanzees; *gestures in orangutans, subadult gorillas, and siamangs; *gestural communication in Barbary macaques; and *a comparison of the gestures of apes and monkeys. This book will appeal to psychologists, anthropologists, and linguists interested in the evolutionary origins of language and/or gestures, as well as to all primatologists. A CD insert offers video of gestures for each of the species.

The aim of this volume is to bring together the research in gestural communication in both nonhuman and human primates and to explore the potential of a comparative approach and its contribution to the question of an evolutionary scenario in which gestures play a signuificant role.

This volume comprises refereed papers and abstracts from the 7th International Conference on the Evolution of Language (EVOLANG7), held in Barcelona in March 2008. As the leading international conference in the field, the biennial EVOLANG meeting is characterized by an invigorating, multidisciplinary approach to the origins and evolution of human language, and brings together researchers from many fields including anthropology, archeology, artificial life, biology, cognitive science, computer science, ethology, genetics, linguistics, neuroscience, paleontology, primatology, psychology and statistical physics.The latest theoretical, experimental and modeling research on language evolution is presented in this collection. It includes contributions from leading scientists such as Derek Bickerton, Rudolf Botha, Camilo Cela Conde, Francesco d'Erico, Susan Goldin-Meadow, Simon Kirby, Gary Marcus, Friedemann Pulvermller and Juan Uriagereka.

This book proposes a detailed picture of the continuities and ruptures between communication in primates and language in humans. It explores a diversity of perspectives on the origins of language, including a fine description of vocal communication in animals, mainly in monkeys and apes, but also in birds, the study of vocal tract anatomy and cortical control of the vocal productions in monkeys and apes, the description of combinatory structures and their social and communicative value, and the exploration of the cognitive environment in which language may have emerged from nonhuman primate vocal or gestural communication.

Multimodal approach to primate communication with focus on its cognitive foundations and how this relates to theories of language evolution.

Researchers have studied non-human primate cognition along different paths, including social cognition, planning and causal knowledge, spatial cognition and memory, and gestural communication, as well as comparative studies with humans. This volume describes how primate cognition is studied in labs, zoos, sanctuaries, and in the field, bringing together researchers examining similar issues in all of these settings and showing how each benefits from the others. Readers will discover how lab-based concepts play out in the real world of free primates. This book tackles pressing issues such as replicability, research ethics, and open science. With contributors from a broad range of comparative, cognitive, neuroscience, developmental, ecological, and ethological perspectives, the volume provides a state-of-the-art review pointing to new avenues for integrative research.

Unlike any other species, humans can learn and use language. This book explains how the brain evolved to make language possible, through what Michael Arbib calls the Mirror System Hypothesis. Because of mirror neurons, monkeys, chimps, and humans can learn by imitation, but only "complex imitation," which humans exhibit, is powerful enough to support the breakthrough to language. This theory provides a path from the openness of manual gesture, which we share with nonhuman primates, through the complex imitation of manual skills, pantomime, protosign (communication based on conventionalized manual gestures), and finally to protospeech. The theory explains why we humans are as capable of learning sign languages as we are of learning to speak. This fascinating book shows how cultural evolution took over from biological evolution for the transition from protolanguage to fully fledged languages. The author explains how the brain mechanisms that made the original emergence of languages possible, perhaps 100,000 years ago, are still operative today in the way children acquire language, in the way that new sign languages have emerged in recent decades, and in the historical processes of language change on a time scale from decades to centuries. Though the subject is complex, this book is highly readable, providing all the necessary background in primatology, neuroscience, and linguistics to make the book accessible to a general audience.

In this volume, the Gardners and their co-workers explore the continuity between human behavior and the rest of animal behavior and find no barriers to be broken, no chasms to be bridged, only unknown territory to be charted and fresh discoveries to be made. With the beginning of Project Washoe in 1966, sign language studies of chimpanzees opened up a new field of scientific inquiry by providing a new tool for looking at the nature of language and intelligence and the relation between human and nonhuman intelligence. Here, the pioneers in this field review the unique procedures that they developed and the extensive body of evidence accumulated over the years. This close look at what the chimpanzees have actually done and said under rigorous laboratory conditions is the best answer to the heated controversies that have been generated by this line of research among ethologists, psychologists, anthropologists, linguists, and philosophers.

The Emergence of Symbols: Cognition and Communication in Infancy provides information pertinent to the nature and origin of symbols, the interdependence of language and thought, and the parallels between phylogeny and ontogeny. This book clarifies some of the conceptual and methodological issues involved in the search for prerequisites to language. Organized into seven chapters, this book begins with an overview of the distinction between homology and analogy in the study of linguistic and nonlinguistic developments. This text then explains the conceptual and operational definitions for such controversial terms as intention, convention, and symbolic behavior. Other chapters consider the limits and advantages of the correlational method as applied in the research. This book discusses as well the structure and content of early symbol use, both in language and in play. The final chapter examines the processes that underlie imitation and tool use, as they contribute to the child's analysis of his culture. This book is a valuable resource for neural biologists, psychologists, and social scientists.
