Scientists have successfully revived a 24,000-year-old microscopic organism from Siberian permafrost, offering new insight into how life can endure extreme conditions over vast stretches of time.
According to a study published in the journal Current Biology, researchers identified the organism as a rotifer — a tiny, multicellular animal often found in freshwater environments and known for its unusual durability.
The specimen had been frozen deep within Siberian permafrost since the Late Pleistocene, a period that ended roughly 11,700 years ago. Scientists say the surrounding ice-rich soil, known as the Yedoma formation, helped preserve the organism in a stable, frozen state for tens of thousands of years.
After carefully thawing the rotifer under controlled laboratory conditions, researchers observed that it resumed normal biological functions. The organism not only became active again but was also able to reproduce asexually, suggesting that its cellular structures remained intact despite the passage of millennia.
