Which country and year did the world s first creep appear?

On February 23, 97, scientists at the Roslin Institute in Scotland, England, announced that their research team had successfully cloned the goat--- Dolly using goat's somatic cells.

United Kingdom February 23, 1997 Sheep Name: Dolly.

Rosslyn Institute, Scotland, UK.

No, but the country with the richest gymnosperms.

No, but there are many species in China, and it seems that there are some species of birds that only China has.

The first organisms were the bacteria of the primitive oceans... And then slowly evolved to have a higher level of creatures.

The earliest organisms should have been just organisms with nucleotide composition.

All are protists.

It can also be said that they are some proteins that can copy themselves.

If you ask about the oldest fossils of creatures found.

I can still you ...

The oldest creature?

Some virus or something...

Organisms such as algae or single-celled organisms.

China's four national treasures: bai giant panda, golden silk monkey, white-finned dolphin, white-lipped deer.

In addition, there are: South China Tiger, Yangtze Special.

Crocodile, crocodile lizard, giant salamander, Chinese sturgeon, white sturgeon, white-headed langur, rock monkey, Tibetan chief monkey, Przewalski's gazelle, Tibetan antelope, twisted horned antelope, Taiwan serow, wild yak, desert cat, black muntjac, Sichuan mountain partridge, Hainan mountain partridge, black-necked crane, Chinese merganser, white-necked pheasant, yellow-bellied horned pheasant, green-tailed rainbow pheasant, pheasant, black long-tailed pheasant, blue pheasant, brown pheasant, white horse pheasant, Tibetan horse pheasant, blue horse pheasant, spot-tailed hazel pheasant, Hainan tabby open bird, etc.

US scientists have recently discovered the world's oldest microorganism, which has existed for 250 million years, breaking the current record for the oldest organism on Earth and providing the latest justification for the theory that life on Earth may have originated in outer space.

The bacteria, called 2-9-3, is naturally sealed in a salt crystal and is found in a nuclear waste landfill 2,000 feet underground in the desert of New Mexico, USA. Scientists at the University of West Chester in the United States took the bacteria out of the salt crystals in a sterilized environment, and then used a co-catalyst extracted from Anji acid to revive the bacteria that had entered a state of suspended animation.

The researchers first disinfected the surface of the salt crystal, killing the modern bacteria attached to it, and then carefully removed the bacteria from the crystal in a sterilized environment. The researcher explained that this was done to ensure that the bacteria in the crystals did not sneak in by accident during the experimental analysis.

The researchers claim that since the crystal showed no signs of damage, and because it came from a salt crystal that formed 250 million years ago, they believe that the bacteria sealed inside are the same age as the salt crystal, i.e. about 250 million years old. They claim that according to their rigorous disinfection procedures, the bacteria inside the crystal are accidentally contaminated with a chance of only one in a billion. Prior to this, the oldest microorganism on Earth, found on bees preserved in amber, was estimated to be about 25 million to 40 million years old.

Earlier, scientists put forward a theory that life on Earth may have originated from which bacteria attached to comets, meteors or asteroids, which began to take root and multiply on Earth when the comet hit the Earth, and this discovery provides a new supporting argument for this theory 2-9-3 Bacteria can still come back to life after 250 million years after being sealed in salt crystals, which means that microorganisms can theoretically be in a similar state, after a long journey to space. There is still a chance to survive and come to Earth.

Scientists point out that according to this theory, it is possible that the life forms of the entire universe originated in one or two places. These primitive bacterial lifeforms, through the debris produced by meteors hitting the planet, spread around the world over hundreds of millions of years.

Researcher Rosenzweich said: A few years ago, Texas was hit by a meteor. The meteor is 4.5 billion years old and contains a liquid salt crystal.

We can imagine that it is possible that life spread through the universe through these pathways. According to this theory, these life forms may also fall on other planets, including Mars, which is close to us, in other words, Mars may also have life. To this one researcher said:

When we explore Mars, salt crystallization there should be a focus of research. 」

In fact, if this theory is true, it may also bring a new impact on human religious beliefs - if the life forms of the whole universe may follow a certain position, does that also mean that there is a creator in the universe?

American scientists recently searched for salt crystals in Death Valley in eastern California and discovered a buried bacterium that lives up to 34,000 years old and still has vital signs. Scientists say it could be the oldest creature in the world.

According to Schubert Brian, the discoverer of the bacteria, the bacteria are no longer reproducing and no longer consuming energy, but are only in a state of life, and are in a state of atrophy and hibernation. As for why the bacteria have such an astonishing lifespan, he thinks it is probably the reason why they live all year round in "Dunaliella salina", and these salty algae cells may be their food**.

Yes, I was from high school, but at that time, I had to go through the provincial competition to be eligible to participate.
