46,000-year-old worms that were brought back to life from Siberian permafrost.
In 2018, a team of scientists from the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, discovered two species of microscopic roundworms (nematodes) in fossilized burrows in the Siberian permafrost. The worms were estimated to be 42,000 years old, making them the oldest known animals to have been revived from the frozen state.
The scientists named the first species Panagrolaimus davidovi, after the Russian scientist Pavel Vladimirovich Davidov, who was a pioneer in the study of nematodes. The second species was named Plectus haploidus.
The worms were revived by being thawed and then placed in a nutrient-rich solution. Within a few hours, the worms began to move and feed. The scientists were able to observe the worms for several months, and they found that they were able to reproduce and produce offspring.
The discovery of the 46,000-year-old worms has important implications for our understanding of the limits of life. The worms' ability to survive for so long in the frozen state suggests that there may be other organisms that are capable of surviving for long periods of time in extreme environments. This could have implications for the search for life on other planets, as it suggests that life may be able to exist in places that were previously thought to be inhospitable.
The discovery of the 46,000-year-old worms is also a reminder of the fragility of life. The worms were able to survive for so long in the frozen state because they entered a state of cryptobiosis, in which their metabolism slows down to a near-dormant state. However, if the worms had been exposed to even a slight increase in temperature, they would have died.
The discovery of the 46,000-year-old worms is a remarkable scientific achievement, and it has the potential to shed new light on the limits of life and the fragility of our planet.

In 2018, a team of scientists from the Max Planck Institute for Molecular Cell Biology and Genetics in Dresden, Germany, discovered a group of microscopic worms in a fossilized burrow in the Siberian permafrost. The worms were estimated to be 42,000 years old, making them the oldest known animals to have been revived from a state of suspended animation.
The scientists named the worms Panagrolaimus davidovi, after the Russian scientist who first discovered them. The worms are about 1 millimeter long and have a simple body plan. They are not parasitic, and they feed on bacteria and other microorganisms.
The scientists were able to revive the worms by thawing them out and placing them in a warm, moist environment. The worms quickly began to move and feed, and they even started to reproduce. This is the first time that scientists have been able to revive animals that have been frozen for so long.
The discovery of these ancient worms has implications for our understanding of the limits of life. It shows that some animals can survive for tens of thousands of years in a state of suspended animation. This could have implications for the search for life on other planets, as it suggests that life could potentially survive in extreme environments.
The discovery of these worms is also a reminder of the fragility of the Earth's permafrost. The permafrost is a vast storehouse of ancient organic matter, and it is thought to contain billions of tons of carbon. If the permafrost melts, this carbon could be released into the atmosphere, contributing to climate change.
The discovery of these ancient worms is a remarkable scientific achievement, and it has implications for our understanding of life on Earth and beyond. It is a reminder of the fragility of the Earth's permafrost, and it highlights the need to protect this important ecosystem.
Here are some additional details about the worms:
- They are nematodes, a type of roundworm.
- They are microscopic, about 1 millimeter long.
- They are not parasitic, and they feed on bacteria and other microorganisms.
- They were found in a fossilized burrow in the Siberian permafrost.
- They are estimated to be 46,000 years old.
- Scientists were able to revive them by thawing them out and placing them in a warm, moist environment.
- The worms quickly began to move and feed, and they even started to reproduce.
This discovery is a significant step forward in our understanding of the limits of life. It shows that some animals can survive for tens of thousands of years in a state of suspended animation. This could have implications for the search for life on other planets, as it suggests that life could potentially survive in extreme environments.
