石峁遗址人群来源哪里社会结构如何？古DNA研究破解谜题

Core Viewpoint - The research on the Shimao site, a significant Neolithic archaeological site in China, reveals the origins, social structure, and relationships of its population through advanced ancient DNA studies, providing crucial insights into early state formation and social organization in East Asia [2][4][5]. Group 1: Research Findings - The research team conducted a comprehensive ancient DNA study over 13 years, analyzing 169 ancient human bone samples from the Shimao site and surrounding areas, leading to definitive genetic evidence regarding the population's origins and social structure [2][4]. - The study confirms that the main population of the Shimao culture originated from the late Yangshao culture in northern Shaanxi, establishing a continuity in cultural and population development [4][6]. - The Shimao culture exhibits a complex social organization with a clear patrilineal structure, as evidenced by a family tree spanning four generations, primarily established by high-status male individuals [9][11]. Group 2: Cultural Interactions - The research highlights close genetic ties between the Shimao culture and surrounding groups, including the Taosi culture, northern steppe populations, and southern rice-farming communities, indicating extensive interactions among prehistoric agricultural and pastoral populations [4][8][11]. - The findings illustrate a dynamic formation process of the Shimao culture, characterized by a stable genetic backbone from local Yangshao populations while maintaining long-term interactions with various groups from central plains, steppes, and southern regions [8][11]. Group 3: Significance of the Study - This study is the first of its kind to utilize genetic evidence to explore the social structure and organization of a large-scale prehistoric urban site, marking a significant advancement in understanding early state formation in East Asia [4][11]. - The research provides a foundational model for understanding the evolution of early states in China, contributing to the broader discourse on the origins of complex societies and the development of early Chinese civilization [5][11].
