Scientists claim to have found signs of life in two worms extracted from patches of Siberia’s permafrost dating back 30,000-40,000 years ago.

The discovery was made by a group of Russian scientists from four different institutions in Moscow, working in collaboration with Princeton University. The study’s aim was to find out if multicellular organisms could be revived after an extended period of laying dormant in extreme cold.
