Representing a wide range of disciplines -- biology, sociology, anthropology, economics, human ethology, psychology, primatology, history, and philosophy of science -- the contributors to this book recently spent a complete academic year at the Center for Interdisciplinary Research (ZiF) discussing a plethora of new insights in reference to human cultural evolution. These scholars acted as a living experiment of ""interdisciplinarity in vivo."" The assumption of this experiment was that the scholars -- while working and residing at the ZiF -- would be united intellectually as well as so.
