Back in 1995, researchers studying the ancient soil composition in an exposed Siberian riverbank found 70 fossilized Ice Age squirrel burrows, some of which were stashed with a lot of fruits and seeds from the ice age. Permafrost had exceptionally preserved one of the seed species. Researchers at the Russian Academy of Sciences recently decided that they would give a shot to culturing tissue from the seeds.
The result came in the shape of a narrow-leafed campion plant. The tissue developed into 36 flowering plants within weeks. Team leader Svetlana Yashina who recreated Siberian conditions in the lab, intends to travel to Siberia again in the summers to look for even older burrows and seeds.
