中国科学院×兰州大学合作最新Science论文：狗与人类近万年来的共迁移历史

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].
