多项研究表明，人类肠道微生物在史前全球迁移过程中随之传播和演变。123一项发表在《自然》期刊的研究追踪了古代人类跨越大陆迁徙与其肠道菌群变化的关联，揭示了微生物多样性在人类地域移动中的演变规律。3研究追踪到非洲与南美洲之间的古代肠道联系，证实肠道微生物群与古代人类的全球迁移模式存在关联。1
这些发现揭示了肠道微生物与人类远古迁徙之间的历史连接，说明我们的肠道菌群在人类跨大陆移动的过程中随之传播和演变。13
New research has revealed that human gut microbiota spread and evolved as ancient peoples migrated across the globe.123 The findings establish a direct connection between the composition of ancestral gut microbiomes and patterns of human migration throughout history, with scientists tracing ancient intestinal microbial links between Africa and South America.1 Research institutions including those at UC Santa Barbara and Stanford Medicine, alongside findings published in Nature, have documented how these microbial communities traveled with humans during their prehistoric journeys across continents.13
The study illuminates the relationship between human health and ancient migration patterns by tracking how gut bacterial diversity changed as people moved across different regions.13 This research demonstrates that understanding the evolution of human gut microbiota provides insight into both the history of human migration and the transformation of microbial populations over time.123
