The giant tortoise was spotted in Ecuador̵7;s Galapagos National Park in 2019 and is part of a species that is thought to have been extinct for over 112 years.
The tiny creatures successfully resurrected and reproduced after being frozen for 24,000 years, according to a study published by Russian scientists on Monday.
Bdelloid rotifers are known for their ability to survive in extremely low temperatures. As has been seen, they can survive 6-10 years in temperatures as low as -4 degrees Fahrenheit. The animal samples were taken from frozen soil extracted from frozen soil in northeastern Siberia.
when they were brought back to the lab They don’t just dissolve. But rotifers reproduce asexually using a process known as parthenogenesis. They are also able to provide food.
Stas Malavin, a researcher at the Soil Cryology Laboratory at the Pushchino Scientific Center for Biological, said: “Our report is the hardest proof to date that multicellular animals are resistant to tens of thousands of years of cryptobiosis. which is a state of almost complete metabolism” research in Russia
The study, published in Current Biology, also found that these animals were able to withstand the slow formation of ice crystals that occur during freezing. This indicates that there is a certain mechanism to protect the entire body from extremely low temperatures.
Rotifers are just one of many organisms that have survived thousands of years of freezing. The nematode, a type of worm, was recovered in 2018 from the barren soils of Siberia in sediments that are more than 30,000 years old.
Dead mammals, such as mammoths, were once found in frozen soil. And despite the enormous difference between them and the rotifers, Malavin said the findings represent progress.
“Of course, the more complex the organisms It was even harder to keep it alive by freezing. and for mammals It is not possible at the moment, however, to move from unicellular organisms to organisms with gut and brain. It’s a huge step forward,” he said. Multicellular organisms can be frozen and stored for thousands of years. then can be resurrected which is the dream of many novelists.”
