Explores the cultural side of language evolution. This book proposes a framework based on linguistic selection and self-organization. It investigates how particular types of language systems can emerge in the population of language game playing agents and how they can continue to evolve in order to cope with changes in ecological conditions.

The Talking Heads Experiment, conducted in the years 1999-2001, was the first large-scale experiment in which open populations of situated embodied agents created for the first time ever a new shared vocabulary by playing language games about real world scenes in front of them. The agents could teleport to different physical sites in the world through the Internet. Sites, in Antwerp, Brussels, Paris, Tokyo, London, Cambridge and several other locations were linked into the network. Humans could interact with the robotic agents either on site or remotely through the Internet and thus influence the evolving ontologies and languages of the artificial agents. The present book describes in detail the motivation, the cognitive mechanisms used by the agents, the various installations of the Talking Heads, the experimental results that were obtained, and the interaction with humans. It also provides a perspective on what happened in the field after these initial groundbreaking experiments. The book is invaluable reading for anyone interested in the history of agent-based models of language evolution and the future of Artificial Intelligence.

What is it that makes us human? This is one of the most challenging and important questions we face. Our species' defining characteristic is language - we appear to be unique in the natural world in having such an incredibly open-ended system for putting thoughts into words. If we are to truly understand ourselves as a species we must understand the origins of this strange and unique ability. To do so, we need to answer some of the most intriguing questions in contemporary scientific research: Where did language come from? How did it evolve? Why are we unique in possessing it? This book, for the first time, brings together the leading thinkers who are trying to unlock the puzzle of language evolution. Here we see the latest ideas and theories from fields as diverse as anthropology, archaeology, artificial life, biology, cognitive science, linguistics, neuroscience, and psychology. In a series of seventeen well-written and accessible chapters we get an unrivalled view of the state of the art in this exciting area. Current controversies are revealed and new perspectives uncovered, in a clear and readable guide to the latest theories. This collection marks a major step forward in our quest to understand the origins and evolution of human language. In doing so it sheds new light on the process of evolution, the workings of the brain, the structure of language, and - most importantly - what it means to be human. Language Evolution is essential reading for researchers and students working in the areas covered, and has been used as a textbook for courses in the field. It will also attract the general reader who wants to know more about this fascinating subject.

Leading scholars report on current research that demonstrates the central role of cultural evolution in explaining human behavior. Over the past few decades, a growing body of research has emerged from a variety of disciplines to highlight the importance of cultural evolution in understanding human behavior. Wider application of these insights, however, has been hampered by traditional disciplinary boundaries. To remedy this, in this volume leading researchers from theoretical biology, developmental and cognitive psychology, linguistics, anthropology, sociology, religious studies, history, and economics come together to explore the central role of cultural evolution in different aspects of human endeavor. The contributors take as their guiding principle the idea that cultural evolution can provide an important integrating function across the various disciplines of the human sciences, as organic evolution does for biology. The benefits of adopting a cultural evolutionary perspective are demonstrated by contributions on social systems, technology, language, and religion. Topics covered include enforcement of norms in human groups, the neuroscience of technology, language diversity, and prosociality and religion. The contributors evaluate current research on cultural evolution and consider its broader theoretical and practical implications, synthesizing past and ongoing work and sketching a roadmap for future cross-disciplinary efforts.

Charles Darwin changed the course of scientific thinking by showing how evolution accounts for the stunning diversity and biological complexity of life on earth. Recently, there has also been increased interest in the social sciences in how Darwinian theory can explain human culture. Covering a wide range of topics, including fads, public policy, the spread of religion, and herd behavior in markets, Alex Mesoudi shows that human culture is itself an evolutionary process that exhibits the key Darwinian mechanisms of variation, competition, and inheritance. This cross-disciplinary volume focuses on the ways cultural phenomena can be studied scientifically—from theoretical modeling to lab experiments, archaeological fieldwork to ethnographic studies—and shows how apparently disparate methods can complement one another to the mutual benefit of the various social science disciplines. Along the way, the book reveals how new insights arise from looking at culture from an evolutionary angle. Cultural Evolution provides a thought-provoking argument that Darwinian evolutionary theory can both unify different branches of inquiry and enhance understanding of human behavior.

Wolfgang Wildgen presents three perspectives on the evolution of language as a key element in the evolution of mankind in terms of the development of human symbol use. (1) He approaches this question by constructing possible scenarios in which mechanisms necessary for symbolic behavior could have developed, on the basis of the state of the art in evolutionary anthropology and genetics. (2) Non-linguistic symbolic behavior such as cave art is investigated as an important clue to the developmental background to the origin of language. Creativity and innovation and a population's ability to integrate individual experiments are considered with regard to historical examples of symbolic creativity in the visual arts and natural sciences. (3) Probable linguistic 'fossils' of such linguistic innovations are examined. The results of this study allow for new proposals for a 'protolanguage' and for a theory of language within a broader philosophical and semiotic framework, and raises interesting questions as to human consciousness, universal grammar, and linguistic methodology.

There are few linguistic phenomena that have seduced linguists so skillfully as grammatical case has done. Ever since Panini (4th Century BC), case has claimed a central role in linguistic theory and continues to do so today. However, despite centuries worth of research, case has yet to reveal its most important secrets. This book offers breakthrough explanations for the understanding of case through agent-based experiments in cultural language evolution. The experiments demonstrate that case systems may emerge because they have a selective advantage for communication: they reduce the cognitive effort that listeners need for semantic interpretation, while at the same time limiting the cognitive resources required for doing so.
