This is very cool. from many sources, this one BBC news. Russian scientists recovered seeds and plant tissue of Silene stenophylla that squirrels had squirreled away in their hybernations burrows 30,000 years ago. The layers are now 20 to 40 meters deep, among bones of wooly mammoths and other ice age mammals. The seeds did not grow, but scientists were able to sprout placental tissue from the frozen plants. There are subtle differences between these and contemporary specimens - genetic drift/evolution? Genetic damage due to long term "storage"?
This brings to mind the 2,000 year old Masada date palm seed that was germinated. The seeds had been found in the excavated palace of Herod the great, and were radiocarbon dated as roughly 2,000 years old. If there was a Jesus, he may have eaten dates from this type of palm tree. This specimen is the only living representative of its species, that went extinct 1800 years ago. This species of palm occurs as separate male and female. The gender of this lonely tree is unknown. If either sex, it could potentially be interbred with similar species to regenerate something resembling the Judean date palm.
I've sprouted tomato and chili pepper seeds that were 7 to 10 years old. Somehow that doesn't compare!
Sentient Biped, I think that name is familiar. I looked up "Silene stenophylla" and found
It is very similar to a plant I grow called Silene vulgaris; I don't know where I got it:
This is fascinating!
