Evolutionists believe they are unlocking how frozen microbes stay alive for 100,000 years

Microbes found buried deep in Siberian permafrost may be able to survive over extremely long timescales using protein repair genes

Microbes isolated from Siberian permafrost appear to have remained alive for more than 100,000 years, based on an analysis of their DNA. Their genetic overlap with other species suggests such astonishingly long lifespans may be widespread among the closest living relatives of all organisms with complex cells.

Other microbes have been isolated from extremely ancient marine sediments – some more than 100 million years old – but it remains unclear whether individual organisms can survive over those stretches of time. “I can’t run an experiment that long,” says Karen Lloyd at the University of Southern California. “[Time] is the weirdest variable to work with.”

A Mummified Cave Bear With Soft Tissue Found In Siberia

Siberia seems to be a treasure drove for ancient animals. Scientists have found wolves, a burly unicorn and a horse with blood flowing from it and cave lions that were not able to be fossilised despite being 10,000 years old

 Now, they have discovered a mummified cave bear, It has soft tissue, including its fur and even its black nose. 

Reindeer hunters have found the cave bear (Ursus spelaeus) mummy on Bolshoy Lyakhovsky island, in the East Siberian Sea brown bear (U. arctos) and the polar bear (U. maritimus). 

 The article in live science also brought to live the fact that they were there for almost a million years: After living in Eurasia since at least 300,000 years ago, cave bears mysteriously went extinct some 25,000 to 30,000 years ago, Humans likely hunted the bears to extinction, a 2019 study in the journal Scientific Reports found.

Mammoth Found In Siberia – And Sharks In Mammoth Cave

Siberia seems to be a treasure drove for ancient animals. Scientists have found wolves, a burly unicorn and a horse with blood flowing from it and cave lions that were not able to be fossilised despite being 10,000 years old.

The last two links are in Finnish.

Now, Fragments of the skeleton were found by local reindeer herders in the shallows of Pechevalavato Lake on the Yamalo-Nenets region a few days ago. They found part of the animal's skull, the lower jaw, several ribs, and a foot fragment with sinews still intact.

Woolly mammoths are thought to have died out around 10,000 years ago, although scientists think small groups of them may have lived on longer in Alaska and on Russia’s Wrangel Island off the Siberian coast.
Russian television stations on Friday showed scientists looking for fragments of the skeleton in the lakeside silt.

Scientists have retrieved more bones and also located more massive fragments protruding from the silt. They said it would take significant time and special equipment to recover the rest of the skeleton — if it had all survived in position.

Yevgeniya Khozyainova of the Shemanovsky Institute in Salekhard said in televised remarks that finding the complete skeleton of a mammoth is relatively rare. Such finds allow scientists to deepen their understanding of mammoths.

The ABC copy of the story includes a short video of another remarkable find: Sharks in Kentucky Mammoth Cave. The shark remains, found in the walls of the sediments that must have been an ocean in the past. They date from 330 million years ago.

DNA from a worm in Siberian Permafrost Wriggle to Life –Why Not the Ice-age Horse as Well?

In May, scientists said that they had brought an arctic nematode to life. They are small, about 1 millimeter in length. Some are them are found living 1.3 kilometres (0.8 miles below Earth's surface, "deeper than any other multicellular animal".

Then, why not the ice age foal? Found in last month, from a 100-meters (328-foot) deep Batagaika crater. The horse was 98 centimetres (39 inches) tall. “Its mummified remains were so well-preserved by icy conditions that the skin, the hooves, the tail, and even the tiny hairs in the animal's nostrils and around its hooves are still visible.”

Some scientist are interested. Among them is Woo-Suk Hwang, a stem-cell researcher and cloning pioneer South Korea. They " are already collaborating in an attempt to clone a woolly mammoth."

Others are not so optimistic. However, Dna has already been excavated from dinosaur bone.
