Core Viewpoint - The research published in Science reveals genomic evidence of the co-dispersal of dogs and humans across Eastern Eurasia during the Holocene, highlighting the long-term and indispensable role of dogs in human societies [2][3][8]. Group 1: Research Findings - The study analyzed 73 ancient dog genomes from the late Pleistocene to early Holocene, providing clear evidence of the genetic relationship between dogs and human populations, indicating their simultaneous migration over time and space [3][6]. - The research included 17 newly sequenced ancient dog genomes, with 14 samples from ancient dogs in China, marking the first acquisition of ancient dog genomes from China [6]. - The findings suggest a connection between dog lineages and specific ancient human groups from Eastern Europe to Eastern Siberia, including ancient Siberians, eastern hunter-gatherers, East Asians, and steppe pastoralists [6][8]. Group 2: Historical Context - As the first domesticated animal, dogs likely spread alongside different cultural groups during the late Pleistocene and Holocene [6]. - The study constructed a lineage evolution map of dogs from East Asia to Western Eurasian steppes, revealing multiple changes in dog ancestry that correspond with the migrations of specific hunter-gatherers, farmers, and pastoralists [6]. Group 3: Implications - The research underscores the integral role of dogs in human civilization, suggesting that they have been a part of human societies for at least 10,000 years [3][8].

记者从中国科学院昆明动物研究所获悉，该研究所王国栋研究员带领的国际合作团队，近日完成了17个古代家犬的基 因组测序，其中包括来自河西走廊，新疆和内蒙古的14个中国古代家犬，这是科学家首次获得中国古代家犬基因组。 加上团队取得的已发表古基因组数据，共获得了73个古代犬基因组，构建了从东亚到西欧亚草原的家犬血统演变图 谱。相关研究成果北京时间11月14日在国际学术期刊《科学》发表。 据了解，这一基于古基因组分析的方法将扩展到其他家养动物，如马牛羊等家畜，进一步揭示它们在人类历史中的作 用，发掘国内家养动物丰富的遗传资源与潜力，为动物资源的开发利用提供更坚实的理论基础。 （总台央视记者 帅俊全 褚尔嘉） △欧亚大陆家犬与人类共迁移示意图 家犬是人类第一个驯化的动物，考古证据表明至少一万年前欧亚大陆多处均出现了犬的身影，其起源、扩散以及与人 类迁徙的互动关系等科学问题对于理解动物驯化和人类文明传播都至关重要，因此长期受到学界的关注。早期基因组 研究表明，家犬早在两万年前就已出现了血统分化并于欧亚大陆广泛扩散，但这些扩散是否与特定人类文化群体相 关，以及家犬在古代社会中的角色，尚缺乏全面的基因组层面的研究。中国作为家犬 ...
