This essay reflects on the fact that as we learn more about the biological underpinnings of our language faculty, the dominant evolutionary narrative coming out of the linguistic tradition most explicitly oriented towards biology ("biolinguistics") appears increasingly implausible. This text offers ways of opening up linguistic inquiry and fostering interdisciplinarity, taking advantage of new opportunities to provide quantitative, testable hypotheses concerning the complex evolutionary path that led to the modern human language faculty. The essay is structured around three main themes: (i) renewed appreciation for the comparative method applied to cognitive questions, leading to the identification of elementary but fundamental abstractions in non-linguistic species relevant to language; (ii) awareness of the conceptual gaps between disciplines, and the need to carefully link genotype and phenotype without bypassing any "intermediate" levels of description (certainly not the brain); and (iii) adoption of a "philosophical" outlook that puts the complexity of biological entities front and center.

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.

The contributions in this volume cover a wide range of theoretical and methodological issues and raise a number of new questions that indicate the future direction of grammaticalization studies. The volume focuses on issues such as grammaticalization and lexicalization; the unidirectionality hypothesis; the issue of the relevance of contexts for grammaticalization; the description of grammaticalization paths. Much of the current work concentrates on such categories, as discourse markers, honorifics or classifiers, which have not previously been central to works on grammaticalization. Other studies take a new perspective on known grammaticalization paths by applying concepts adopted from other linguistic fields, such as prototype theory, morphocentricity, or by discussing their findings from a comparative or typological angle, presenting data from a large number of languages, often based on extensive empirical investigations of written and spoken text corpora.

The question of how language emerged is one of the most fascinating and difficult problems in science. In recent years, a strong resurgence of interest in the emergence of language from an evolutionary perspective has been helped by the convergence of approaches, methods, and ideas from several disciplines. The selection of contributions in this volume highlight scenarios of language origin and the prerequisites for a faculty of language based on biological, historical, social, cultural, and paleontological forays into the conditions that brought forth and favored language emergence, augmented by insights from sister disciplines. The chapters all reflect new speculation, discoveries and more refined research methods leading to a more focused understanding of the range of possibilities and how we might choose among them. There is much that we do not yet know, but the outlines of the path ahead are ever clearer.

The rise of the multi-billion dollar ancestry testing industry points to one immutable truth about us as human beings: we want to know where we come from and who our ancestors were. John H. Relethford and Deborah A. Bolnick explore this topic and many more in this second edition of Reflections of Our Past. Where did modern humans come from and how important are the biological differences among us? Are we descended from Neandertals? How should we understand the connections between genetic ancestry, race, and identity? Were Native Americans the first to inhabit the Americas? Can we see evidence of the Viking invasions of Ireland a millennium ago even in the Irish of today? Through engaging examination of issues such as these, and using non-technical language, Reflections of Our Past shows how anthropologists use genetic information to suggest answers to fundamental questions about human history. By looking at genetic variation in the world today and in the past, we can reconstruct the recent and remote events and processes that have created the variation we see, providing a fascinating reflection of our genetic past.

Language has no counterpart in the animal world. Unique to Homo sapiens, it appears inseparable from human nature. But how, when and why did it emerge? The contributors to this volume - linguists, anthropologists, cognitive scientists, and others - adopt a modern Darwinian perspective which offers a bold synthesis of the human and natural sciences. As a feature of human social intelligence, language evolution is driven by biologically anomalous levels of social cooperation. Phonetic competence correspondingly reflects social pressures for vocal imitation, learning, and other forms of social transmission. Distinctively human social and cultural strategies gave rise to the complex syntactical structure of speech. This book, presenting language as a remarkable social adaptation, testifies to the growing influence of evolutionary thinking in contemporary linguistics. It will be welcomed by all those interested in human evolution, evolutionary psychology, linguistic anthropology, and general linguistics.

Human adults appear different from other animals in their ability to form abstract mental representations that go beyond perceptual similarity. In short, they can conceptualize the world. This apparent uniqueness leads to an immediate puzzle: WHEN and HOW does this abstract system come into being? To answer this question we need to explore the origins of adult concepts, both developmentally and phylogenetically; When does the developing child acquire the ability to use abstract concepts?; does the transition occur around 2 years, with the onset of symbolic representation and language? Or, is it independent of the emergence of language?; when in evolutionary history did an abstract representational system emerge?; is there something unique about the human brain? How would a computational system operating on the basis of perceptual associations develop into a system operating on the basis of abstract relations?; is this ability present in other species, but masked by their inability to verbalise abstractions? Perhaps the very notion of concepts is empty and should be done away with altogether. This book tackles the age-old puzzle of what might be unique about human concepts. Intuitively, we have a sense that our thoughts are somehow different from those of animals and young children such as infants. Yet, if true, this raises the question of where and how this uniqueness arises. What are the factors that have played out during the life course of the individual and over the evolution of humans that have contributed to the emergence of this apparently unique ability? This volume brings together a collection of world specialists who have grappled with these questions from different perspectives to try to resolve the issue. It includes contributions from leading psychologists, neuroscientists, child and infant specialists, and animal cognition specialists. Taken together, this story leads to the idea that there is no unique ingredient in the emergence of human concepts, but rather a powerful and potentially unique mix of biological abilities and personal and social history that has led to where the human mind now stands. A 'must-read' for students and researchers in the cognitive sciences.
