In the "Ice Age" series of movies, wonderful animation techniques are used to portray the difficult survival path of the earth in the face of some prehistoric creatures during the Ice Age. Manny the mammoth was only completely extinct more than 4,000 years ago, and many frozen remains of mammoths have been found in the Siberian region of Russia.
In 2017, a frozen mammoth cub was found under the permafrost of Siberia, Russia, and under the protection of ice and snow, the mammoth's hair and body were preserved intact, and when it was unearthed, it resembled a sleeping baby elephant rather than a fossil. The reason why it can be preserved so completely is that Russia's Siberia has a lot of permafrost layers, which can be like a large ice cellar to protect the carcasses of long-haired elephants from decay.
The discovery of complete fossils of prehistoric organisms in Russia's Siberian region is no longer unusual, and Russian researchers are also very serious about it, and they also intend to set up a research laboratory to prepare to resurrect mammoths through DNA replication. Imagine how eye-catching it is to resurrect prehistoric creatures, not only to gain global attention but also to bring about a wave of global waves.
Therefore, they had to extract the mammoth's DNA and then revive the mammoth through cloning technology.
DNA is the biological code that is kept in biological cells, and humans can extract DNA from biological cells, and then they can undergo embryonic development, and then clone organisms that take this DNA.
The mammoth is a large animal that lived between 300,000 and 10,000 years ago and only went extinct about 3,700 years ago.
Mammoths attract people's attention with their tall figures and long elephant hair and tall tusks, generally about 2.5 to 3.5 meters tall, weighing about 6 tons, suitable for extremely cold climates.
It has a long back hair of up to 50 cm, a layer of fluff under the long hair, and a thickness of up to 9 cm of subcutaneous fat.
The mammoth's head and neck also have towering humps that store large amounts of fat, which are adaptations to living in areas with colder winters and less food.
Although the well-preserved corpses of mammoths have been found in many places, it is still difficult to actually extract the DNA of mammoths. Because they couldn't find the biological cells of the well-preserved mammoths.
So to clone a prehistoric creature mammoth, you need well-preserved mammoth cells, but there is no record of well-preserved mammoth cells. Russian researchers have also rubbed the heat of a mammoth, which also needs to be found in the future.
