According to a new study, it was understood that a multicellular organism survived in Siberia, which had been frozen for 24,000 years.
Scientists have unearthed the tiny aquatic multicellular organism known as the “bdelloid rotifer” from the Alayeza River in the Russian Arctic.
After thawing, the bdelloid rotifer was able to reproduce asexually after thousands of years, with a rebirth known as cryptobiosis.
Previous research has indicated that these animals can survive for up to 10 years after freezing.
But this new study, published Monday in Current Biology, found that cryptobiosis in bdelloid rotifers could persist for thousands of years, if not indefinitely.
“The idea is that a multicellular organism can be frozen and stored for thousands of years and then come back to life, which is the dream of many fiction writers,” said Stas Malavin, of the Russian Institute of physico-chemical and biological problems, at the Press Association. .
More research is needed to better understand the result, Malavin said.

Scientists freeze and thaw dozens of bdelloid rotifers in a lab to study the research process.
Using the carbon-14 method, the age of the bdelloid rotifer sample was determined to be 23,960 to 24,485 years.
Bdelloid rotifers are a class of rotifers found in freshwater environments around the world.
These animals are known for their endurance in very difficult conditions. According to the New York Times, bdelloid rotifers can withstand low oxygen, high acidity and years of dehydration, and are one of the highest radioactive resistance animals in the world.
On the other hand, some reports indicate that a nematode worm (roundworm) and some plants and algae can come back to life after thousands of years.
