For over three decades, Ötzi the Iceman has been viewed as a frozen time capsule, but a groundbreaking 2026 study in the journal Microbiome reveals a startling truth: he is a living, dynamic ecosystem.
三十多年來，奧茨冰人一直被視為一個冷凍的時間膠囊，但 2026 年發表在《微生物組》(Microbiome) 期刊上的一項開創性研究揭露了一個驚人的事實：他其實是一個活躍且充滿動態的生態系統。
Scientists from Eurac Research discovered that the 5,300-year-old mummy hosts active, cold-adapted yeasts capable of thriving even at -6°C.
Eurac 研究中心的科學家發現，這具擁有 5,300 年歷史的木乃伊身上寄生著活躍且適應低溫的酵母菌，牠們甚至在攝氏零下 6 度下仍能生長。
These microbes are not just present; they are metabolically active.
這些微生物不僅僅是存在而已，牠們還具有代謝活性。
The mummy’s microbiome consists of three layers: remnants of Ötzi’s original Copper Age gut bacteria, cold-adapted yeasts that arrived during his time in the ice, and modern contaminants introduced since his discovery in 1991.
木乃伊的微生物群由三層組成：奧茨原始銅器時代腸道細菌的殘留物、在他冰封期間進入的適應低溫酵母菌，以及自 1991 年被發現以來引入的現代污染物。
Instead, they must be managed as active biological environments.
相反地，必須將牠們視為一個活躍的生物環境來管理。
By studying these ancient microbes, researchers gain invaluable insights into both the evolution of the human gut and the complex challenges of preserving history in an ever-changing world.
透過研究這些古老的微生物，研究人員可以獲得有關人類腸道演化以及在瞬息萬變的世界中保存歷史所面臨的複雜挑戰等寶貴見解。
