Abstract:
At the transition from the Middle (2100e1700 BC) to Late Bronze Age (1700e1400 BC) in the central Eurasian steppe, significant changes occurred in patterns of settlement and mortuary practice. Traditional
interpretations link these changes to shifts from semi-settled agro-pastoral communities to more mobile forms of pastoralism. However, correlations between subsistence strategies and shifts in social
and ritual practices have been infrequently tested. This paper explores the nature of subsistence economies in two populations from the sites of Bestamak (MBA) and Lisakovsk (LBA) in northern Kazakhstan. Carbon and nitrogen stable isotope analysis of bone collagen was undertaken to understand dietary intake. The close clustering of isotope values indicates homogeneity in subsistence practices for these two communities spanning the transition. Therefore, while changes occurred in social and ritual practice,
subsistence regimes stayed relatively uniform at the transition. Results of this research add to previous literature, revealing that dietary intake of pastoral populations in the Eurasian steppe are much moreintricate than previously believed.
