Fruit preserved more than 30,000 years in Siberia’s permafrost yields a living flower
A flower that last bloomed while mammoths walked the Earth has been reborn, regenerated from a piece of fruit frozen in Siberian permafrost.
It’s the oldest flowering plant ever grown from preserved tissue, Russian scientists report online February 21 in Proceedings of the National Academy of Sciences.
