考古研究包括对人类遗骸骨胶原的稳定碳和氮同位素分析表明,在日本内陆中部地区的绳纹时期,他们严重依赖陆地食物。然而,由于生态系统中15n富集因子的变化和背景同位素的变化,很难根据胶原蛋白化学定量评价考古人类遗骸的食肉性程度。为了克服这些问题,更准确地评估具有较强陆地适应性的史前人类的饮食,本研究对绳纹时期的两个内陆人群进行了骨胶原中单个氨基酸的氮同位素分析。结果表明,这两个种群主要依赖c3 -植物为基础的陆地生态系统,消耗的水生资源很少。此外,它们的平均营养位置(2.7)更接近于狐狸(2.8-3.0),而不是纯食草动物(2.0-2.2),并且随着时间的推移变化不大。这些结果是第一个证据,表明内陆绳纹人可能比传统认为的有更多的肉食性饮食。
Archaeological studies including stable carbon and nitrogen isotope analyses of bone collagen from human remains have suggested their heavy dependence on terrestrial foods during the Jomon period in the inland central region in Japan. However, it is not easy to quantitatively evaluate the extent of carnivory for archaeological human remains based on the bulk collagen chemistry, because of variable15N-enrichment factor along the trophic step and background isotopic variations in ecosystems. In order to overcome these problems and more precisely evaluate diets of prehistoric humans who strongly adapted to terrestrial environment, in this study we applied nitrogen isotope analysis of individual amino acids in bone collagen to two inland human populations in the Jomon period. Our results suggest that the two populations were predominantly dependent on the C3-plant-based terrestrial ecosystem and consumed little aquatic resources. Furthermore, their mean trophic positions (2.7 for both cases) are closer to that of the fox (2.8–3.0) rather than those of pure herbivores (2.0–2.2), and show little change over time. These results are the first evidence that inland Jomon populations may have had more carnivorous diets than is traditionally considered.
