本研究报告的古DNA（aDNA）和稳定同位素分析的8个狗骨骼元素的Cathlapotle网站下哥伦比亚河的美国西部。aDNA分析证实了这些元素是狗（Canis lupus familiaris）。两个单倍型被发现，这两个组内的狗进化枝A，并有斑片状分布到北部的不列颠哥伦比亚省和南部的特奥蒂瓦坎（墨西哥）。同位素分析表明，狗的饮食蛋白质几乎完全来自海洋来源。下哥伦比亚河的民族历史记录和Cathlapotle动物考古记录表明，虽然海鱼是饮食的重点，但当地的饮食更多样化，包括陆地生物和淡水鱼。这种明显的差异增加了狗被选择性喂养的可能性。因此，在这种情况下，它们的饮食可能不是人类饮食的密切代表。(C)2015爱思唯尔有限公司版权所有。
This study reports ancient DNA (aDNA) and stable isotope analyses of eight dog skeletal elements from the Cathlapotle site on the Lower Columbia River of the western United States. The aDNA analysis confirmed the elements as dogs (Canis lupus familiaris). Two haplotypes were found, both of which group within dog Clade A, and have patchy distributions to the north in British Columbia and as far south as Teotihuacan (Mexico). The isotopic analysis showed that the dogs' dietary protein was derived almost exclusively from marine sources. Lower Columbia River ethnohistoric accounts and Cathlapotle zooarchaeological records indicate that while marine fish were dietary keystones, the local diet was more diverse, and included terrestrial organisms and freshwater fishes. This apparent discrepancy raises the possibility the dogs were selectively fed. Thus their diet may not be a close proxy for human diet in this context. (C) 2015 Elsevier Ltd. All rights reserved.
