Is it possible to revive extinct animals? The first to ask this question was most likely the old Neanderthal who hunted mammoths to obtain valuable hide and flesh under the ice age conditions. Of course, he did not manage to revive the mammoth, but after a few thousand years, his distant descendant, a man, wants to do this. All he needs for historical success is a sample of the soft tissue of an extinct animal. So what kind of animals can we actually raise again?
How can extinct animals be resurrected?
If you were once a fan of the movie "Jurassic Park", then you probably know that extinct old animals can be brought to life thanks to modern technology such as cloning. To clone an animal, scientists must find at least the smallest part of the intact DNA that is easiest to find in animals that have recently disappeared from the planet.
As the observations show, the best chance of recovering extinct species is to clone those creatures whose remains were in permafrost for a long time. The lucky ones who died at the right time and in the right place include woolly mammoths, marsupials, saber-toothed cats and birds like Moa and Dodo.

Which animals can be raised soon?
As you know, the most anticipated animals returning to planet Earth today are mammoths. The last individuals of these creatures lived on the island of Wrangel about 3.5 thousand years ago. To test the viability of permafrost mummified cells, a group of Japanese and Yakut scientists extracted several mammalian muscle cells from a mammoth that had died about 28,000 years ago. Scientists transplanted the obtained nuclei into the oocytes of mice to observe possible signs of biological activity.
Despite the fact that scientists could not start the process of cell division, some cells still showed some biological activity. Well, even such a result can be seen as a success and a big step in the resurrection not only of mammoths but also of other extinct animals. In your opinion, will the resurrection of extinct animals be useful or not? Let's try to discuss this problem in our telegram chat.

Scientists are suggesting that marsupials, recently extinct – in the 1930s, for example – can be brought back to life. Samples of these unique animals can still be found in museums in Australia.
In addition to the marsupial wolf is planned to bring birds like Moa back to life. Maybe this name does not mean anything, but these birds are considered the largest of all species that ever lived on the planet. Moa died of extinction by humans about 600 years ago, but despite this very sad fact, her feathers and eggs have been completely preserved.
Another bird that could soon have a chance of resurrection is the dodo. Dodo is the closest relative of the modern pigeons that lived on the island of Mauritius. The fact that these birds developed for thousands of years completely isolated from the outside world, they lacked a sense of self-preservation, which was used by the discoverers of the island of Mauritius and completely destroyed the Dodo as a species.
After a man had destroyed a large number of animals, he began to restore the lost and correct his own mistakes. Will we be wiser this time? Well, time will tell.
