从东部奇瓦瓦沙漠和德克萨斯州中部发现的人类遗骸的δ 13 C值的分布表明,在早、晚白垩世至少存在两个不同的同时代饮食人群。我们采用了一种新的统计技术,norma概率图,以确定不同的饮食人群。得克萨斯州下佩科斯和外佩科斯地区一个种群的δ 13 C值反映了奇瓦瓦沙漠C4和CAM植物的长期使用。第二组,包括所有的得克萨斯州中部的个人和一些个人从下佩科斯,严重依赖于C3植物更常见的爱德华兹高原或在墨西哥的橡树松树林。从东部奇瓦瓦沙漠的下佩科斯地区的广泛的稳定碳同位素比值迫使重新考虑狩猎采集解决和社会组织模式提出的该地区。这项研究强调了对狩猎采集者史前饮食和社会组织进行更多研究的必要性。
Abstract The distribution of δ13C values from human remains recovered in the eastern Chihuahuan Desert and central Texas demonstrates the existence of at least two distinct coeval dietary populations during the Early and Late Archaic. We employed a novel statistical technique, norma probability plots, to identify distinct dietary populations. δ13C values from one population in the Lower Pecos and Trans-Pecos regions of Texas reflect the long-term use of Chihuahuan Desert C4 and CAM plants. A second group, consisting of all the central Texas individuals and some individuals from the Lower Pecos, depended heavily on C3 plants more common in the Edwards Plateau or in the oak-pine forests in Mexico. The wide range of stable carbon isotope ratios from the Lower Pecos region of the eastern Chihuahuan Desert forces a reconsideration of hunter-gatherer settlement and social organization models proposed for that region. This study highlights the need to conduct more research on hunter-gatherer prehistoric diets and social organization.
