重建饮食可以提供对现代人类起源和进化的更好理解。然而，对东亚早期现代人的饮食了解甚少。牙结石的淀粉分析对珍贵的古人类化石无害，并提供了早期现代人类饮食记录中植物食物来源的最直接证据。本文对东亚最早的现代人--道县浮岩洞古人类牙结石中的淀粉粒进行了研究。我们的结果揭示了120至80 ka之间海洋同位素第5阶段中由橡子、根、块茎、草籽和其他尚未鉴定的植物组成的古人类饮食的最早直接证据。我们的研究还提供了最早的证据，证明橡子可能在生存策略中发挥了重要作用。在晚更新世时期，中国可能有长期使用这些植物的传统。植物性食物是丰富的碳水化合物来源，大大增加了人体组织对葡萄糖的高需求。我们的研究首次提供了中国最早直接食用现代人类富含碳水化合物的植物资源。此外，它还有助于阐明早期现代人类在中更新世晚期和上更新世早期的进化优势。
Reconstructing diet can offer an improved understanding toward the origin and evolution of modern humans. However, the diet of early modern humans in East Asia is poorly understood. Starch analysis of dental calculus is harmless to precious fossil hominins and provides the most direct evidence of plant food sources in early modern human dietary records. In this paper, we examined the starch grains in dental calculus from Fuyan Cave hominins in Daoxian (South China), which were the earliest modern humans in East Asia. Our results reveal the earliest direct evidence of a hominin diet made of acorns, roots, tubers, grass seeds, and other yet-unidentified plants in marine isotope stage 5 between 120 and 80 ka. Our study also provides the earliest evidence that acorns may have played an important role in subsistence strategies. There may have been a long-lasting tradition of using these plants during the Late Pleistocene in China. Plant foods would have been a plentiful source of carbohydrates that greatly increased energy availability to human tissues with high glucose demands. Our study provides the earliest direct consumption of carbohydrates-rich plant resources from modern humans in China for the first time. In addition, it also helps elucidate the evolutionary advantages of early modern humans in the late Middle and early Upper Pleistocene.
