The research project titled "Towards a renewed vision of the First Alpine Agro-Pastoral Societies Through the Analysis of Dietary Practices, Lifestyles, and Peopling Dynamics" is funded by the Swiss National Science Foundation (SNSF grant FNS 10521F-205059 / 2022-2026). It concerns a prehistoric period, the Neolithic, spanning from 5500 to 2200 BCE in the Swiss-Italian Alps. This period is marked by significant changes in lifestyles and societal functions. The project's main goal is to decode the dietary behaviors, lifestyles, and mobility of these early agro-pastoral Alpine communities using interdisciplinary investigative methods. It focuses on regions with remarkable human occupations between the Middle Neolithic and the Bell Beaker period. The funerary discoveries in these areas are significant both in quality and quantity. This rare and valuable situation in archaeology allows for the study of populations from a defined territory, spanning a chronological period with no major gaps. Nearly 400 individuals, including key and unpublished Neolithic Alpine sites such as Petit-Chasseur and Don Bosco in Switzerland, and Saint-Martin-de-Corléans in Italy, are being studied.
