Domestic taurine cattle (Bos taurus) were introduced to China from Central Asia between 3600-2000 cal BCE. Most of the earliest domestic cattle remains in China come from sacrificial or ritual contexts, especially in the form of oracle bones used in divination rituals. These oracle bones became closely tied to royal authority and are the source of the earliest written inscriptions in ancient China. In this article, we use ancient DNA to identify uninscribed bovine oracle bones from the Longshan period archaeological sites of Taosi and Zhoujiazhuang (late third millennium BCE). We found that in addition to making oracle bones out of domestic cattle scapulae, people also used aurochs (wild cattle: Bos primigenius) scapulae for oracle bone divination. Wild water buffalo (Bubalus mephistopheles) were also exploited at Zhoujiazhuang, but we did not identify water buffalo oracle bones in our analysis. We propose some morphological criteria that may be useful for distinguishing between these bovine species, but conclude that it is not always possible to identify bovine scapulae based on morphology alone. Our results indicate that wild and domestic bovines were sometimes present at the same sites and their bones were used in similar ways to make oracle bones. This raises the possibility that these species interbred and that people in ancient China may have experimented with managing indigenous Chinese wild bovines.
Shimao City is considered an important political and religious center during the Late Neolithic Longshan period of the Middle Yellow River basin. The genetic history and population dynamics among the Shimao and other ancient populations, especially the Taosi-related populations, remain unknown. Here, we sequenced 172 complete mitochondrial genomes, ranging from the Yangshao to Longshan period, from individuals related to the Shimao culture in northern Shaanxi Province and Taosi culture in southern Shanxi Province, Middle Yellow River basin. Our results show that the populations inhabiting Shimao City had close genetic connections with an earlier population in the Middle Neolithic Yangshao period of northern Shaanxi Province, revealing a mostly local origin for the Shimao Society. In addition, among the populations in other regions of the Yellow River basin, the Shimao-related populations had the closest maternal affinity with the contemporaneous Taosi populations from the Longshan period. The Shimao-related populations also shared more affinity with present-day northern Han populations than with the minorities and southern Han in China. Our study provides a new perspective on the genetic origins and structure of the Shimao people and the population dynamics in the Middle Yellow River basin during the Neolithic period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
