The goal of the proposed project is to understand the differences in terms of the use of glues between Neanderthals and modern humans in Europe in comparison to early modern humans in Africa. The use of glue takes a central position in debates on the evolution of complex cognition. Indeed, the capacity to mount a stone tool on an organic haft indicates the existence of a capacity to anticipate future needs and to plan and it marks the development of complex technology.
