Scientists discovered a female microscopic roundworm that has been stuck deep in Siberian permafrost for 46,000 years, The Washington Post reported. When they revived it, the worm started having babies via a process called parthenogenesis, which doesn't require a mate. According to a press release, the worm spent thousands of years in a type of dormancy called cryptobiosis. In that state, which can last almost indefinitely, all metabolic processes pause, including "reproduction, development, and repair," the University of Hawaiʻi at Mānoa reported. In a study published Thursday in the journal PLOS Genetics, scientists reported that after sequencing the worm's genome,...
