Worms

For more than two decades scientists have been collecting frozen microbes from deep layers of the Siberian permafrost, to see if they can be thawed and brought back to life. In the most recent revival experiments, a team of genetic researchers from Russia and Germany first reawakened and then identified a previously undiscovered nematode species, which they claim is 46,000 years old. Assuming this is true, this is the most ancient type of microscopic lifeform to have even been recovered from the freeze-dried Siberian soil. In an article about their research just published in PLOS Genetics, the genetic researchers describe how they confirmed the existence of this new species of roundworm, which was unearthed near Siberia’s Kolyma River and has
