natural wonder / Buried in the snow for 24 thousand years 'Zombie' started making its own clone as soon as it came out

Scientists have extracted a tiny zombie that was alive 24 thousand years ago from the Arctic's permafrost, the coldest place in the world. But as scientists made him alive, he made his own clones. This scientific feat has been seen in a laboratory in Russia. These are microscopic zombie creatures that have been found in different aquatic areas of our earth for 50 million years. But buried in the Arctic's permafrost, these microscopic zombies were dormant. There was no effect on the bodies of these creatures buried in the snow for thousands of years.

These strong and tough creatures are also called Bdelloid Rotifers or Wheel Animals. Because these creatures have a bunch of circular hairs around their mouth. Rotifers are multicellular microscopic organisms found in clear water on Earth. But during the Ice Age they went to icy areas and allowed to freeze in permafrost. This was his way of survival.

Russian scientists first discovered modern rotifers that can tolerate temperatures up to minus 20 degrees Celsius. He was brought back alive after being in this condition for 10 years. But now scientists have discovered rotifers that were buried in the ancient Siberian permafrost. These belong to the Pleistocene epoh period. That is, from 11,700 years to 26 lakh years old. The study was published on June 7 in the journal Current Biology.

When these Bdelloid Rotifers were resurrected, they began to produce clones asexually, which were genetic duplicates. This process is called parthenogenesis. It is the process in which an organism carries its offspring without mating with the opposite sex. This common scientific language is called untouched genealogy.

Siberian permafrost is where the land has solidified over two or more years. Any living or dead creature can remain safe inside it for centuries. For example, last year a carcass of a bird was found in the same area, which was actually 46,000 years old. But seeing him, it seemed that he had been killed recently and was buried here. Apart from this, a mummified bear was found in this area only in 2020. Whose age was 39 thousand years. Many parts of his body are still completely safe.

Russian scientists believe that after being buried in ice for thousands of years, they come out alive. It's a natural wonder to clone yourself immediately after that. But some plants and organisms reactivate themselves when they are taken out of the permafrost. This is a very rare sight. Because after being buried in the snow for thousands of years, if an organism comes back alive or active, then it is its surprising feature.

In 2012, scientists described how a new plant developed from the tissue of an undeveloped fruit after 30,000 years of being frozen in Siberian permafrost. Two years after that, the moss, which had been buried in the ice for 1500 years in Antarctica, was seen back active and developing. Apart from this, micro-organisms which are nematodes were also found in Siberia in two parts. One was 32 thousand years old, the other 42 thousand years old. But both became alive and active back in the year 2018.

If an organism reactivates its metabolic system after being buried in ice for thousands of years, it is called cryptobiosis. This usually happens mostly with creatures that are buried in snow. Scientists call these creatures zombies for this reason because they come back alive from the dead state.

Researcher Stas Malavin of the Institute of Physiochemical and Biological Problems in Soil Science in Pushchino, Russia, said that rotifers have a habit of completing the process of cryptobiosis. If it gets buried in the snow, or it dries up. Whenever they get an environment favorable to them, they activate themselves under this scientific process. Also, immediately start making their own genetic clone, so that their population continues to grow.

Stas Malavin said that when buried in ice, they preserve chemical substances like chaperone proteins in their body. As soon as the conditions improve, they activate themselves by completing the cryptobiosis process with the help of these. After that start making clones. Not only this, they also have a method by which they can repair their DNA. So that their cells can get protection and protection from reactive oxygen based species. For these new studies, Russian scientists drilled 11.5 feet below the foothills of the frozen Alazeya River in Siberia. Took a sample of permafrost there. Where radiocarbon dating revealed that it is about 24 thousand years old soil. When the sample was examined, Bdelloid Rotifers were found in it. These were in a cryptobiotic state. Cones first isolated them from the soil. Then it was investigated whether the soil of the permafrost and whether these organisms were infected or sick with new and modern microorganisms. After this, the soil, including these organisms, was placed in a petri dish and given a favorable environment. to see if they activate. or creatures
