In continuo movimento. La migrazione come strategia adattativa

Human populations - and biological populations in general - have always redistributed, moved, relocated, either by necessity (due to fluctuations in ice ages and interglacials) or by choice. Our natural history suggests how human migration, characterized by ecological and climatic instabilities, is constitutive of our identity as a species. The aim of this paper is to show how cognitive plasticity, our behavior, and our ability to adapt to our environment have been shaped by migration processes. Through migration and the conquest of lands and places, new species emerge as a result of geographic separation, and peoples are remixed, ensuring the consolidation of existing genetic heritage and the introduction of new genetic variants. Migration is neither an exceptional wind, nor a historical accident, nor an emergency to be combated, but an activity that represents a valuable adaptive strategy that has breathed and continues to breathe life into plural human evolution.
