Climatic or dietary change? Stable isotope analysis of Neolithic–Bronze Age populations from the Upper Ob and Tobol River basins

摘要: Dietary changes in the populations inhabiting southwest Siberia and northern Kazakhstan indicate concurrent economy, at same time marking beginnings of East–West interaction across Eurasia. The introduction domestic animal species Near Eastern origin, such as sheep goat, dramatically changed lives local population. Past palaeodietary research using stable isotope analysis has mainly focussed on pastoral Bronze Age period. It is crucial, however, to assess diets humans animals from earlier periods (Neolithic/Chalcolithic) order understand timing nature dietary change during Kazakhstan, particular possible contribution environmental influencing shifts. In this paper, we report results 55 human 45 faunal samples (Upper Ob River) (Tobol River basin), rang...
