Wetin scientists don see for Siberia go make you shock. Dem don bring back to life one small animal wey don dey freeze inside ice for 24,000 years. Na rotifer, one microscopic animal wey get many cells, and e don show say e fit survive extreme cold pass wetin we dey think before.
Dem carry this rotifer from deep inside Siberian permafrost, from one place dem call Late Pleistocene Yedoma formation. This place na ice-rich loam wey don dey there since ancient times. After dem thaw am carefully for laboratory, the animal no only wake up, but e begin dey do normal things again. E even begin reproduce asexually.
This discovery na big proof for wetin dem dey call cryptobiosis. For this state, organism metabolism slow down almost to zero, and e fit survive conditions wey for kill am. Lead researcher Stas Malavin talk say, “Our report is the hardest proof as of today that multicellular animals could withstand tens of thousands of years in cryptobiosis.”
This rotifer revival no be small thing wey just happen quick quick. E show sustained activity and reproduction, meaning say e cellular structures remain intact despite all the years wey e spend frozen. This dey raise new questions about how biological materials fit resist degradation for such long time.
The implications dey big pass just this small animal. Scientists don dey speculate about limits of suspended animation, especially for space travel and long missions. While this no mean say human cryopreservation don near, e dey expand the scientific foundation wey dem need to explore such possibilities.
Malavin explain am well: “The takeaway is that a multicellular organism can be frozen and stored as such for thousands of years and then return back to life – a dream of many fiction writers.” But e quick add say for mammals, e no dey possible yet. Still, moving from single-celled organism to organism with gut and brain na big step forward.
This step forward dey for understanding how cells avoid damage from ice crystal formation, radiation, and time itself. Each insight fit help fields like biotechnology and astrobiology, where survival for extreme environments na central question.
The study wey dem publish for Current Biology highlight how extreme cold fit effectively halt biological time. The environment wey preserve the specimen remain with remarkable clarity, and the team describe am well for their research.
While similar behavior don dey observe for single-celled organisms and some simple animals before, this case stand out because rotifers get more complex internal structures, including digestive systems. This make the discovery even more significant for science community.
