To analyze the partnership between the isotopic overall performance and also the social condition of the Imdang anybody, individuals on the Joyeung C section are included here having talk
Based on archaeological features and burial structures, the Joyeung district was divided into Joyeung C (I, II) and E (I, II, III). In this study, humans (n = 30) from Joyeung E were measured, but humans (n = 18) from Joyeung C were previously published 56 . According to the archaeological and isotope data, all 48 individuals were categorized into either elite (n = 12) or retainer (n = 33) groups. A simple t-test found that there is a significant difference in the ? 15 N values between the elites and retainers (? 15 N: t = 6.6, P < 0.0001). The mean ? 15 N value for the elites is 2.5‰ higher than the retainers (elite: 12.2 ± 1.3‰ > retainer: 9.7 ± 1.0‰). This likely indicates that the elites consumed more animal protein than their retainers. Furthermore, there is a significant difference in ? 13 C values between the elites and the retainers (? 13 C: t = ? 3.8, P < 0.0001) (Fig. 3). The mean ? 13 C value for the elites is 1.0‰ lower than those of the retainers (elite: ? 18.8 ± 0.8‰ < retainer: ? 17.8 ± 0.8‰). These results suggest that the elites consumed less C4 plants than their retainers. These isotopic data demnonstrate that there is a significant difference in diets according to the social class (elite vs. retainer), even though both were buried in similar wooden chamber tombs.
