Robin Dunbar speaks at the 2008 Nobel Conference on social brain theory and on what it is to be human and how it is that we came to be that way, which is the essence of the ongoing research in the Lucy to Language project. Or, as he puts it: How it is that humans arent just great apes. Robin I. M. Dunbar is Professor, Evolutionary Anthropology; Director, Institute of Cognitive & Evolutionary Anthropology, University of Oxford, United Kingdom; Co-Director of the British Academys Centenary Research Project, Lucy to Language: The Archaeology of the Social Brain, a multidisciplinary project involving several universities, studying how the human brain evolved and the role language played.
