石子潭14号遗址的三块磨石。23，000 - 19，500年前）的使用磨损和残留物分析，以探讨人类在末次盛冰期（LGM）的适应性，当时资源普遍匮乏，植物性食物可能在人类饮食中变得越来越重要。结果表明，这些工具被用来处理各种植物，包括小麦科和Paniceae草，豇豆，山药，天花粉和葫芦根。块茎是旧石器时代狩猎采集者的重要食物资源，而Paniceae草在驯化前约12，000年就被开发利用。对某些类型的植物群进行密集开发的悠久传统帮助旧石器时代的人们了解了这些植物的特性，包括它们的药用价值，并最终导致了植物的驯化。这一研究揭示了晚更新世华北地区农业起源之前广泛的生存策略的深层历史。
Three grinding stones from Shizitan Locality 14 (ca. 23,000-19,500 calendar years before present) in the middle Yellow River region were subjected to usewear and residue analyses to investigate human adaptation during the last glacial maximum (LGM) period, when resources were generally scarce and plant foods may have become increasingly important in the human diet. The results show that these tools were used to process various plants, including Triticeae and Paniceae grasses, Vigna beans, Dioscorea opposita yam, and Trichosanthes kirilowii snakegourd roots. Tubers were important food resources for Paleolithic hunter-gatherers, and Paniceae grasses were exploited about 12,000 y before their domestication. The long tradition of intensive exploitation of certain types of flora helped Paleolithic people understand the properties of these plants, including their medicinal uses, and eventually led to the plants' domestication. This study sheds light on the deep history of the broad spectrum subsistence strategy characteristic of late Pleistocene north China before the origins of agriculture in this region.
