They manage to “resurrect” the wolf “Game of Thrones”, which has extinct for 10,000 years

The news of the alleged A terrible wolf scheduleextinct species that inspired George R.R. Martina in his description The wolf of the huargo de Game of ThronesThere are social networks throwing fire. Those who are responsible for the specified scientific milestone, the company Colossal biological sciencesThey assure that they returned this extinct animal 10,000 years ago in order to return it to a place where it should never disappear. Everything sounds very commendable, but the story has a huge lagoon on which the scientific community is trying to warn the population.

The first and most important is that the study of colossal biology was not revised. Neither a couple, nor something like that. All that we have is the word of his scientists and some photographs. In addition, the scientific procedure, which, by the visible, completed, would not be a de -textor as such. On the other hand, it is very pleasant to want to return to the extinct animal, where it disappeared. But will it really be useful now for its ecosystem? Perhaps the terrible wolf will not move to other predators of their habitat and will not reduce animal populations that will become their prey too large?

Ecosystems follow a very easy balance to break. For this reason, in recent years, the danger of invasive species has been warned. These are species that for one reason or another spell on a habitat that is not yourThe displacement of local species for reasons such as competition for available resources or excess depression, among other things. In this case, we will not talk about any other habitat, but in one of the Another era. Many scientists have repeatedly warned about the risk of what this would mean. Not only with a terrible wolf, but also with other species, whose de -sekite is in the project. Perhaps the medicine was worse than the disease; But, in any case, in this case it seems that the medicine is not as described.

What happened to the terrible wolf?

A terrible wolf He lived between North America and the Argentine pampa During the late Pleistocene and the early Golocene. That is, within 125,000 years to 10,000 years ago.

There are many fossil records, especially on the site located in Los -Ageles, known as Ranchu La BreaThe field was found there Up to 3500 skeletons full. They were very similar to the current gray wolf. Almost the same size, although more reliable. Despite this, they have differential factors, which, according to the analysis, indicate that they may be separated from the line of life. 5.7 million yearsTherefore, they are the family of the current wolves, but far.

Thanks to the large number of fossils that were found, there is a rather approximate idea of ​​how they were, although you cannot know logically for sure. As for his DNA, it was very difficult to study. The first attempts to extract and analyze the genetic sample were impossible, since Smol The reign in the breakdown of the gap left the samples very damaged.

Finally, in 2021 it was possible to analyze a sample of DNA. This was what allowed him to clarify him divergence 5.7 million years ago. According to a study published after this analysis, “terrible wolves developed in isolation The ancestors of the Pleistocene of these species. “Scientists add that their results” also support the early origin of terrible wolves in the new world, while the ancestors of gray wolves, coyots and Jole They developed in Eurasia And they colonized North America relatively recently. “

Way

In fact, the desire to derive species is not like scientists Colossal BiossakaHe tried to make a field for more than 100 years.

The first to offer something like that, there were two German scientists who in the 1920s insisted on returning life to life Eurasian UroThis animal walked on the ground for millennia, but in 1627 its last famous sample died after its population disappeared a little from Excessive hunting and loss of their habitat.

Genetic editing methods at that time were science fiction. Therefore, these two scientists have chosen Selective propagation. They spent a lot of time, crossing various races of cattle, while the animal is very similar to what is described, it was EuroAzi Uro. This animal was baptized as Bull is damn And this led to great interest in the media, but soon it was discredited by scientists who insisted that it could be an animal similar to EuroAzii Euro, but Not the same view.

Later, the emergence of genetic editing methods and, above all, cloning, proposed a new way to return extinct views to life. After the success of cloning Dolly sheep He tried to do something like that with extinct views. It is here, in Spain, exactly where he tried Clone BucardoThis subspecies of Montez Kabra repaid the field in 2000, but the scientists were careful with Save DNA samples From the last samples. Most attempts have not reached pregnancy. Only one clone managed to be born, but did not even live.

To do something like that, you must have a very well -preserved sample of the animal DNA that you want to clone. It is difficult with the species that only fossils were extracted. Therefore, the colossal biossaka wanted to resurrect a terrible wolf through Genetic modification of the gray bookThe spoiler field: This is not the case.

This is not a terrible wolf

Romulo, Remo and Khalisi These are the three terrible puppies of the wolf that were born from this colossal scientific experiment. Now they are really young from a terrible wolf?

Jeremy AustinAustralian DNA Center explained in statements The science of warning This, in fact, is what these scientists did Modify the Gray Wolf DNA As long as the animal, similar to the fact that, in their opinion, was a terrible wolf. They can not even be sure, because the canides are morphologically very similar, and you cannot know for sure how it was. From colossal biology, they note that this is a terrible wolf, because it is white, but it is not so simple.

Austin himself also explained that from the fact that these scientists made public, it is known that they did About 20 modifications to the DNA of a gray wolf. This, if we take into account what is known about the genetic analysis carried out in 2021, would be insufficient. Austin notes that tens of thousands of additional publications will be needed, if not more.

Therefore, it is very bold to say that they resurrected a terrible wolf. In the same way as now they do not seem to do the same with the mammoth. A few years ago, they indicated that they also intend to welcome this. They set as a date 2027 or 2028But now they only managed to get Muscles with giant hair. Devince, if achieved, not what this company does. But, in any case, it is not very clear that it will be useful to achieve this. We must worry much more about work so that the views that still surround us do not extinguish, instead of making extinct species. In this case, avoiding mistakes of the future is much more useful than the amendment in the past.
