古民族植物学的观点对于理解过去的生活方式至关重要,但在古印度研究中仍然代表性不足。我们提出了新的考古植物学和放射性碳的燃烧功能内分层的文化成分在康利洞穴,俄勒冈州,重申列入植物的饮食中的古印第安人群体的数据。康利洞穴5的三个特征的植物遗迹表明,人们在夏季和秋季的几个月里觅食不同的旱地类群和范围狭窄的湿地植物。这些数据为已知的更新世食物经济增加了新的分类群,并支持了这样一种观点,即配备了西方传统工具包的群体拥有广泛,灵活的饮食。从大陆的角度来看,这项工作有助于越来越多的研究表明,至少在新仙女木时期,区域适应性的生存策略已经到位,远西地区的一些觅食者可能比北美其他地方的古印第安人更早地将更广泛的植物,包括小种子,绿叶蔬菜,水果,仙人掌和地下植物纳入他们的饮食。在新兴的古印度植物食品经济中,越来越多的多样性和看似低等级的资源出现,这表明需要探索各种营养变量来解释早期觅食行为的某些方面。
Paleoethnobotanical perspectives are essential for understanding past lifeways yet continue to be underrepresented in Paleoindian research. We present new archaeobotanical and radiocarbon data from combustion features within stratified cultural components at Connley Caves, Oregon, that reaffirm the inclusion of plants in the diet of Paleoindian groups. Botanical remains from three features in Connley Cave 5 show that people foraged for diverse dryland taxa and a narrow range of wetland plants during the summer and fall months. These data add new taxa to the known Pleistocene food economy and support the idea that groups equipped with Western Stemmed Tradition toolkits had broad, flexible diets. When viewed continentally, this work contributes to a growing body of research indicating that regionally adapted subsistence strategies were in place by at least the Younger Dryas and that some foragers in the Far West may have incorporated a wider range of plants including small seeds, leafy greens, fruits, cacti, and geophytes into their diet earlier than did Paleoindian groups elsewhere in North America. The increasing appearance of diverse and seemingly low-ranked resources in the emerging Paleoindian plant-food economy suggests the need to explore a variety of nutritional variables to explain certain aspects of early foraging behavior.
