'To 'seafood' or not to 'seafood'?' An isotopic perspective on dietary preferences at the Mesolithic-Neolithic transition in the Western Mediterranean

摘要

Stable isotope investigations of the Prehistory of the Western Mediterranean have increased exponentially during the last decade. This region has a high number of Mesolithic and Neolithic carbon and nitrogen isotope ratio data available compared with other world areas, resulting from the interest in the "transition" between hunter-gathering and farming. This type of analysis is important as one of the few tools that give direct information on the poorly understood dietary transition from hunter-gatherer to agro-pastoralist subsistence in the Mediterranean Basin. Carbon and nitrogen stable isotope analysis on bulk collagen are especially useful for exploring marine vs. terrestrial protein input and therefore assess marine resource exploitation by these two different lifestyles. Gathering together all isotopic data for these chronologies we show that the Western Mediterranean underwent a unique/distinct Neolithisation process. These data show a gradual dietary shift in aquatic resource consumption during the transition to farming that contrasts to elsewhere in Europe. (C) 2018 Elsevier Ltd and INQUA. All rights reserved.
