Old Frozen Worms Come Back to Life – AT SCHOOL

A sample of microscopic worms that were suspended in a Siberian freezer for 42,000 years came back to life after being thawed, say the scientists.

The results, represent the first evidence of multicellular organisms returning to life after spending

Nematodes are tiny worms that typically measure about one millimeter in length and have impressive abilities.

Some are 1.3 kilometers below the surface of the Earth, deeper than any other multicellular animal. . Some worms that live on an island in the Indian Ocean may develop one of five different mouths, depending on the type of food available.

A sample was taken from a fossilized squirrel burrow near the Alazeya River in the northeastern part of Yakutia. Russia, according to estimated deposits at around 32,000 years, reported the 'Live Science & # 39 ;. The other permafrost sample came from the Kolyma River in northeastern Siberia, and the age of the deposits was around 42,000 years, according to scientists.

Isolated worms were two known species of nematodes: Panagrolaimus detritophagus and Plectus parvus. By defrosting the worms, the researchers saw them move and eat, making them the first evidence of the "natural cryopreservation" of multicellular animals. This is not the first organism to wake up for millennia in an icy suspension. Earlier, another group of scientists had identified a giant virus that was revived after 30,000 years in Siberian permafrost. PTI
