科学家在毛毛长毛巨人遗骸中发现百万年前的细菌,对古代微生物的进化提供了洞察力。 Scientists find million-year-old bacteria in woolly mammoth remains, offering insights into ancient microbial evolution.

科学家在羊毛大毛象遗骸中发现了最古老的宿主相关细菌DNA,可追溯到100多万年前。 Scientists have discovered the oldest host-associated bacterial DNA in woolly mammoth remains, dating back over one million years. 研究人员对483个长毛象样本中的微生物DNA进行了分析,确定了6个一致的微生物组,包括与现代非洲大象血液中毒有关的一些潜在致病细菌。 Analyzing microbial DNA from 483 mammoth samples, researchers identified six consistent microbial groups, including some potentially pathogenic bacteria related to those causing blood poisoning in modern African elephants. 这一发现使人们深入了解微生物如何与长毛象一起演化,如何影响它们的健康、适应和可能灭绝。 This discovery offers insights into how microbes evolved alongside mammoths and influenced their health, adaptation, and possibly extinction.
