Ice Age Flower Resurrected

Using a pioneering experiment, the Sylene stenophylla has become the oldest plant ever to be regrown and it is fertile, producing white flowers and viable seeds.
The seeds date back 30,000 to 32,000 years and raise hopes that iconic Ice Age mammals like the woolly mammoth could also eventually be resurrected.

The researchers, who published their findings in Proceedings of the National Academy of Sciences in the US, said the results prove that permafrost serves a natural depository for ancient life forms.
"We consider it essential to continue permafrost studies in search of an ancient genetic pool, that of pre-existing life, which hypothetically has long since vanished from the earth's surface," the scientists said in the article.

Canadian researchers had earlier regenerated some significantly younger plants from seeds found in burrows.

Svetlana Yashina of the Institute of Cell Biophysics of the Russian Academy Of Sciences, who led the regeneration effort, said the revived plant looked very similar to its modern version, which still grows in the same area in northeastern Siberia.

The Russian research team recovered the fruit after investigating dozens of fossil burrows hidden in ice deposits on the right bank of the lower Kolyma River in northeastern Siberia.

They were firmly cemented together and often totally filled with ice, making any water infiltration impossible - creating a natural freezing chamber fully isolated from the surface.

The burrows were located 125ft (38m) below the present surface in layers containing bones of large mammals, such as mammoth, woolly rhinoceros, bison, horse and deer.

"The squirrels dug the frozen ground to build their burrows, which are about the size of a soccer ball, putting in hay first and then animal fur for a perfect storage chamber," said Stanislav Gubin, one of the authors of the study, who spent years rummaging through the area for squirrel burrows. "It's a natural cryobank."

"If we are lucky, we can find some frozen squirrel tissue," said Mr Gubin. "And this path could lead us all the way to mammoth."


Although I am sure many people have already read this remarkable pre-Easter tale of rebirth, I definitely thought it was worth reposting for those who haven't.  Thanks to Eudora Linde of WTVM for first alerting me to this.


  1. I did read this story this morning and was fascinated, amazed, and delighted, all at the same time. Your presentation of the report here gives Sylene stenophylla the respect it deserves.

  2. Thank you. It really is an amazing story. Curtis

  3. I am currently investigating the possibility of regenerating plants from long-buried seeds. Will report on progress (if any).

  4. Report back anyway. If the Russkies can do it, so can the....Arlingtonians. Remember who won the Cold War. Curtis

  5. Thank you Linnea. It's quite a story. I'm afraid my friend Chris's seeds (comment just above yours) won't germinate. Permafrost is the answer; backs of cupboard drawers tend to provide poor storage. Please visit again soon. I've visited your beautiful, very affecting blog this morning and I think we have a lot in common, although you say things more concisely than I tend to do. Curtis
