The microscopic organism was brought back to life and reproduced sexually after being frozen in the Siberian freezer for 24,000 years.
Russian scientists have discovered a small ancient animal, called the rotifer bdelloidea, in a soil sample from the Alazeya River in Russia’s far north Yakutia region.
It is known that this multicellular organism, which lives in a freshwater environment all over the world, can survive in the extreme cold.
Previous research has shown that it can survive ten years at minus 20 degrees.
The new case, published in the scientific journal Current Biology, is by far the longest recorded survival period in the frozen state.
The organism was found in soil samples from a depth of 3.5 meters. The material is between 23,960 and 24,485 years old, the study says.
Earth covered with permanent frost, frozen all year round, reveals great scientific secrets for years.
Experts have previously revived microscopic worms from soil taken from two places in northern Siberia more than 30,000 years old.
