Reviving the Past: Ancient Animal, Frozen for 24,000 Years, Emerges from Siberian Permafrost (Video)

   

 

During the Upper Paleolithic era, a multicellular organism was frozen almost the time in history when humans first set foot into North America. About 24,000 years later, it has been found alive after sleeping for millennia.

But the waterway that runs along with the village of Quinhagak, in southwest Alaska, barely freezes now, a testament to the warming temperatures wreaking havoc on the state’s indigenous people and their subsistence way of life.

This turned out to be a very huge discovery and might have changed the theory of how long organisms and perhaps humans can be preserved for generations.

Discovery of Bdelloid Rotifer

Bdelloid rotifer – a freshwater creature – is too tiny to see with the naked eye, measuring around 150 and 700 μm. The microorganism can be found in waters around the world. This animal survived being frozen for many years through a remarkable means of cloning itself multiple times through an asexual reproduction form called parthenogenesis, according to Accuweather.

This discovery, therefore, brought about questions on the reversible standstill lack of life theory or mechanism of the cryptobiosis.

These findings were done by researchers from the Soil Cryology Laboratory in Pushchino, Russia. It was discovered from a soil sample collected from permafrost in northeastern Siberian.

This age discovery was really surprising to the researcher as it felt really unbelievable that the animal was alive and doing well.

The permafrost sample of this creature was collected from the Alazeya River, which flows from Siberia into the Arctic. Researchers also confirmed that there was no movement of the bdelloid rotifer due to the icy nature of the ground.

Research Findings

“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,” Malvin, an author on this study stated.

He further talked about how big this discovery was and how it has totally changed the ideology of organism preservation.

This discovery might have been revolutionary and has added to the small number of organisms that have been found to be able to survive such extraordinary timespans but more are still yet to be uncovered.

The more complex an organism becomes, the more difficult it is to preserve alive, like in mammals, as per Smithsonian Magazine.

The frozen carcass of a 39,000-year-old female woolly mammoth named Yuka from the Siberian permafrost is displayed for an exhibition in Yokohama, suburban Tokyo, at a press preview before the opening. The carcass will be shown to the public during an exhibition at Pacifico Yokohama.

In Russia, a pair of prehistoric nematodes, also called roundworms, were discovered and successfully revived, it is said to have been between 30,000 and 42,000 years old.

Studies have shown that over the years, a lot of organisms have been revived from their frozen state but what makes this new discovery more interesting is that none of these past organisms is as complex as the bdelloid rotifer.

 

Additionally, there have been discoveries on the dead but frozen larger species like the 20,000-year-old woolly rhino that was discovered by a Siberian farmer in the area of Yakutia in 2021 and the 57,000-year-old Pleistocene grey wolf puppy, the most perfectly preserved animal of its kind.

 

More research is still to be made on this study. The hope is that insights from these tiny animals will offer clues as to how better to cryo-preserve the cells, tissues, and organs of other animals, including humans.
