Frozen Microscopic Animals Brought Back to Life after 24,000 Years

Post by Dragon Sat Jun 12, 2021 4:25 am

Microscopic multicellular animals called bdelloid rotifers are known for their ability to survive extremely low temperatures.

They had been reported to survive 6-10 years when frozen between minus 20 and 0 degrees Celsius.

Now, an international team of biologists has successfully revived bdelloid rotifers that have been frozen in the Siberian permafrost for 24,000 years.

A bdelloid rotifer.

In natural, permanently frozen habitats, some organisms may be preserved for hundreds to tens of thousands of years.

For example, stems of Antarctic moss were successfully regrown from an over millennium-old sample covered by ice for about 400 years.
