New achievements in the process of cloning prehistoric mammoths

Researchers are hoping to successfully replicate fine-haired mammoths.

>>>Development technology revives extinct species?

The idea of ​​reviving prehistoric animals seems to only appear in sci-fi films. However, recently, multinational research teams including Russia, the United Kingdom, the United States, Denmark, South Korea and Moldova have confirmed that they have made a new step in the process of cloning smooth fur mammoths.

Scientists used DNA from the fossil of a female mammoth, dating to about 43,000 years. This corpse was found last year in the permafrost in the diamond mine area of ​​the Sakha Republic, Siberia (Russia). They hope that the results of this mammoth mammoth blood test will help provide information on the genetic resources needed, increasing the likelihood of success in the cloning process.

Scientists use the fossilized DNA to recreate this mammoth

This furry mammoth is extinct completely in Eastern Siberia about 4,000 years ago due to climate change and human hunting.

When cutting soft tissue on the fossilized part of the mammoth, scientists were surprised by its integrity. The cut tissue shows the vascular section with a hardened vascular wall, and the inside of the vessel has hemolytic and red blood cells.

Muscle and fat tissue are also well preserved. Besides, the liver is also intact, and the body is generally in good condition. Because it is completely preserved in ice, its status is much better than a body buried normally for 6 months.

The team also said that the mammoth's death was not due to old age. He suffered pain for about 16 to 18 hours, then died. The main sign is the lying position and the position of its hind legs is abnormally prolonged. The cause of the mammoth's death is said to have unfortunately fallen into an ice hole and failed to escape.

During the cloning process, the team will use a female elephant to act as a surrogate mother for the re-mammoth, because elephants are the closest relative to mammoths.

However, Radik Khayrullin, vice president of the Russian Society for Medical Anthropology, said scientists need to uphold the sense of responsibility in conducting research to regenerate this large animal. He emphasized that the purpose of cloning is to distinguish science, rather than merely curiosity.
