Russian scientists revived a bdelloid rotifer — a microscopic multicellular animal — from 24,000-year-old Siberian permafrost, and it reproduced asexually through parthenogenesis. The discovery, published in Current Biology in 2021, represents the longest confirmed survival of a multicellular animal in cryptobiosis and raises questions about what other organisms may emerge as Arctic permafrost continues to thaw at accelerating rates.
