全新世狩猎采集者适应了气候和环境的变化。对绳纹时代末期稻有山贝壳堆中人类骨骼遗骸的碳氮稳定同位素分析揭示了该人群的巨大饮食变化。本研究分析了这些个体的放射性碳年代，以测试饮食的时间变化及其与牙齿消融的关系。材料和方法本研究纳入了29具来自稻有山的人类骨骼遗骸。提取的骨胶原样品纯化为石墨。然后，使用加速器质谱仪对这些样品进行放射性碳定年。结果稻有山地区放射性碳年龄在3,230 ~ 2,140 cal BP之间，有3个占位峰。前期和后期主要以陆地资源消耗和拔牙为主，中期主要以海洋资源消耗和拔牙为主。这些饮食和牙齿消融类型的时间变化与气候变冷和环境变化同时发生，有助于揭示全新世狩猎采集者如何适应不断变化的环境。
ObjectivesHolocene hunter‐gatherers adapted to climatic and environmental changes over time. Carbon and nitrogen stable isotope analysis of human skeletal remains from the Inariyama shell mound of the Final Jomon period have revealed large dietary variations in the population. This study analyzed radiocarbon dates of these individuals to test temporal changes in diet and its relationship with tooth ablation.Materials and MethodsTwenty‐nine human skeletal remains from Inariyama were included in this study. Extracted bone collagen samples were purified to graphite. Then, radiocarbon dating of these samples was performed using the accelerator mass spectrometer.ResultsThe radiocarbon ages of Inariyama ranged about, 3,230–2,140 cal BP and showed three peaks of occupation. In the early and late phases, terrestrial resource consumption and incisor extraction were observed, while marine resource consumption and canine extraction were observed in the middle phase.DiscussionThese temporal changes of diet and tooth ablation types occurred in parallel with climatic cooling and environmental change and help reveal how Holocene hunter‐gatherers adapted to the changing environments.
