Microscopic Worms Lived 46000 Years Ago and Revived After Freezing in Permafrost
by Brian Wang from NextBigFuture.com on (#6DKVR)
Precise radiocarbon dating in a peer reviewed Journal show that Panagrolaimus individuals worms remained in cryptobiosis since the late Pleistocene (~46,000 years) and were revived in 2018. Phylogenetic inference based on our genome assembly and a detailed morphological analysis demonstrate that they belong to an undescribed species, which we named Panagrolaimus kolymaensis. Comparative genome analysis ...
