The evolution of the capacity for spoken language is a focus of intense scientific interest at present. However there is insufficient empirical control on estimates of the date at which this adaptation emerged. The behaviour itself leaves no direct archaeological traces, while adaptation in the brain and the vocal tract is difficult to recognize in fossilized hard tissue. In this project we will address this deficit, undertaking new comparative analyses of the human vocal tract and cranial base with an emphasis on functional adaptations and their hard tissue markers.
FINAL PROJECT REPORT:
The EC-funded HANDTOMOUTH project finished in spring 2010. Feedback from our project officer in Brussels indicates that is was classified by the agency as "an excellent project regarding the achievement of their initial objectives". Two new papers with J. Steele as co-author have been submitted, with Jeroen Smaers as lead author [1,2]. In addition an edited special issue of Philosophical Transactions B is in preparation to appear in 2011, contents as follows:
1. Introduction: What are the implications of an embodied perspective on language origins for the tool use-language relationship in human evolution? - Dr Pier Francesco FERRARI (University of Parma), Professor Leonardo FOGASSI (University of Parma), Dr James STEELE (University College London) and Dr Dietrich STOUT (Emory University)
2. Social influence on tool use, and the interaction of actions and gestures with vocalisation in monkeys – Dr Pier Francesco FERRARI (University of Parma), Professor Leonardo FOGASSI (University of Parma), (University of Parma), Dr Stefano ROZZI (University of Parma)
3. Plasticity and learning: characterization of the neurobiological and behavioural aspects of tool-use in monkeys – Professor Atushi IRIKI (RIKEN Brain Science Institute, Japan)
4. Gestures, either alone or in combination, in apes – Professor Josep CALL (Max Planck Institute for Evolutionary Anthropology, Leipzig)
