In other words, we know that squirrels like to eat food very much, they will collect all kinds of seed food and put them into their caves,

some glaciers The squirrels of the period may not have thought that their seeds hoarded in the caves would be dug again by humans after more than 30,000 years…

2007, A group of experts went to study the caves of ancient squirrels near the Kolyma River in Russia.

At 38 meters below the frozen ground, they found 70 caves of Arctic ground squirrels. In these caves, they accidentally found 600,000 frozen seeds.

These seeds are all surrounded by ice. In the frozen soil layer near them, there are also mammoths, bison, Woolly rhinoceros The bones.

After using radiocarbon dating technology, scientists believe that these seeds came from 32,000 years ago and were buried by a group of Arctic ground squirrels during the ice age.

Of these seeds, the mature seeds are all destroyed. It may be that the squirrels were intentionally destroyed in order to prevent them from sprouting in the hole. Only some immature seeds are intact.

However, three of the immature seeds contain viable embryos.

Scientists extracted and cultured these embryos.

Finally!

After a while, they actually germinated.

Slowly, the longer they grow, the smaller white flowers bloom,

One year later, They have grown their own seeds.

After these seeds are planted, all can survive normally…

This flower is S. angustifolia.

Compared with the present Dionaea muscipula, the Dionysia serrata petals were longer than 30,000 years ago, and the interval between the petals was larger.

At present, no one knows why these seeds can survive for so many years.

Recently, some scientists from Austria have tried to unravel the reason why they can survive for so long by studying the DNA of this plant.

They hope to find out from the research whether there are changes in plant genes that can adapt to very dry, hot or cold conditions.

“This discovery will be very helpful for us to take care of other plants after climate change.”

After this experiment, scientists think Permafrost may be a”reservoir of ancient genes.” Many species that are now extinct can be found in permafrost in the future, and then resurrect them.

“Some plants used to be very important to the ecosystem in ancient times, but then they became extinct. If they can be recovered, it will be useful to us.”

At present, this plant is the oldest seed resurrected by humans.

Before, scientists have also resurrected several Date palm tree.

These date palm trees were discovered many years ago when excavating King Herod’s palace in Israel, and they were stored in an ancient jar.

In 2005, scientists planted several seeds, and now they have grown very large.

In 1995, in a dry river bed in northeast China, a botanist found a Lotus seeds.

At first glance, these plants seem nothing special, but Think about the time they have traveled through thousands and tens of thousands of years. It’s amazing to be in this world…
