Scientists recently discovered and revived a worm that was frozen 46,000 years ago. This worm was frozen in the Siberian permafrost and was brought up from a depth of 40 meters (131.2 feet) below the surface.
This discovery has been published in PLOS Genetics and it states: “Recently, individual nematodes were revived from the Siberian permafrost after remaining dormant. Preliminary analysis indicates that these nematodes belong to the genera Panagrolaimus and Plectus.”

The worm is revived just by rehydrating it with water. After a few hours, the worm began to wiggle and move around. Scientists were surprised to discover this worm is still alive and active after many years.
The worm’s survival was a remarkable discovery. Scientists believe this worm can survive by entering a dormant state.
In cryptobiosis, organisms can reduce their metabolic rate to very low levels, which allows them to survive in harsh environments.
Research mentions: “Surviving in extreme environments for long periods of time is a challenge that only a few creatures can handle. It is not yet fully understood what molecular and biochemical pathways are used by hidden living organisms and how long they can suspend life.”
The discovery of the living worm is known to be an important scientific discovery. This will help scientists gain new insights into the organism’s ability to survive in extreme environments.
It also raises the possibility that other organisms that may have been frozen for thousands of years could still be alive.
The authors mentioned in the article “Our findings here are important for the understanding of evolutionary processes because generation times can range from a few days to millennia and the long survival of individuals. within species can lead to the re-establishment of extinct lineages.”
In summary, this new scientific discovery could have a major impact on our understanding of life on earth. It serves as a reminder that there is so much on this planet that needs to be explored.
