Scientists 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 revival known as cryptobiosis.
Previous research has said 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,” Stas Malavin, from Russia’s Institute of Physicochemical and Biological Problems, told 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 process in the research.
According to the carbon 14 method, the age of the bdelloid rotifer sample was determined between 23,960 and 24,485 years.
Bdelloid rotifers are a class of rotifers found in freshwater environments worldwide.
On the other hand, there are some reports that a nematode worm (roundworm) and some plants and algae can come back to life after thousands of years.
