Ancient Life Revived After 24,000 Years
25 Apr
Summary
- A 24,000-year-old rotifer was revived from Siberian permafrost.
- The microscopic organism resumed normal functions and reproduced.
- Revival offers insights into life's resilience in extreme cold.
A microscopic organism, identified as a rotifer, has been revived after being frozen for 24,000 years in Siberian permafrost. This remarkable feat was achieved by researchers who carefully thawed the specimen, observing its return to normal biological activity and even asexual reproduction. The rotifer had been preserved in the ice-rich Yedoma formation since the Late Pleistocene epoch.
This successful revival of a multicellular animal from such an extended period of cryptobiosis—a state of near-zero metabolic activity—marks a significant scientific advancement. Previous revivals primarily involved simpler, single-celled organisms. The findings underscore life's extraordinary capacity to withstand extreme cold and could inform studies in biotechnology and astrobiology, exploring survival in harsh environments.
