Prehistory, neuroscience, and evolutionary anthropology: a personal journey.

The relationship between anthropology and neuroscience has always been friendly but controversial, because they embrace inclusive common topics (human beings and their brains) although following distinct approaches, often more holistic and speculative in the former field, more reductionist and quantitative in the latter. In recent decades, novel disciplines have been proposed to bridge the gap between anthropology and neuroscience, mostly taking into account their common interest in human evolution. Paleoneurology deals with the study of brain anatomy in extinct species. Neuroarchaeology concerns the study of brain functions associated with behaviours that are of interest according to the archaeological record. Cognitive archaeology investigates the evolution of those behaviours following methods and theories in psychology. These new fields can provide quantitative and experimental support to topics that, to date, have been largely discussed only on a theoretical basis. Nonetheless, working with extinct species necessarily involves many limitations. Consistent theories on the evolution of our cognitive abilities must rely on the integration of different sources of information, on parallel and independent evidence from different fields, and on a proper attitude: openness and caution.
