It is a violent, majestic animal that has disappeared thousands of years ago, apart from artistic renderings in books and on the screen, as in game of Thrones.
Or maybe it’s just a gray wolf with a few changes.
The American Biotech Company Colossal Biosciences made a surprising announcement on Monday and claimed that the company had brought the company back from the dead and thus reached the company’s first successful “Dextincionion”.
Colossally presented videos of the fluffy white wolf puppies, which in his 2,000 hectare habitat roam in an unknown place in the northern USA and mark a big victory for the company, which also works on the revival of the woolen mut, the Dodo and the Tasmanian Tiger.
However, some scientists say that the existence of the wolves is an impressive performance, but they are not exactly as announced.
“I would like to see some of experts examined papers to get a better feeling for what was actually done and what was known and what is not known,” said Hank Greely, director of the Stanford University and Biosciences Center.
A US technology company says it used to use the gene processing to effectively revive the extinct Dire -Wolf, but some are wondering how useful this experiment will be in order to get the extinction from extinction.
He says that seeing that the puppies put a smile on the face and was a welcome surprise in an otherwise dark news landscape.
But in his view, creation is more of a “bad wolf”.
“I think it is important for people to remember that they are not bad wolves. There are gray wolves that have some bad wolf characteristics,” said Greely. “On the other hand, they seem to be closer to Dire Wolves than anything else that has seen for 13,000 years, and that’s pretty cool. And they are hellishly cute.”
Once hunted big prey
The large types of wolf roamed more than 100,000 years of America before they died out about 13,000 years ago.
It was believed that it had hunted great prey such as horses, bison and huge sloths and has largely disappeared because his prey pecies died out – partly because of the hunt by humans.
Beth Shapiro, Chief Scientific Officer from Colossal, said that scientists have extracted DNA from a 13,000 -year -old tooth and a 72,000 year old inner ear from a bad wolf skull and extracted the DNA to assemble genities and sequences.
They found that the gray wolf was the closest living relative – “99.5 percent identical” in DNA, and similar, but larger, larger, muscular and with a lighter coat, a wider skull and a stronger jaw.
Scientists then changed gray wolf cells to give them bad wolf characteristics, which made 20 changes in 14 genes before they created embryos and implant them into large domestic dogs.
Shapiro said three of the eight dogs that were used as replacement mothers, and the mothers were then adopted anonymously by the American human society – “Somewhere out there there are families who adopted a dog who born a weak wolf and they don’t know.”
According to Kolossal, two male puppies, Romulus and Remus, were born on October 1 – she now presented her in the early stages of adolescence – while Khaleesi, a woman, was born on January 30th and is almost at the age at which she can be “the boy”, said Shapiro.
Kevin Campbell, professor at the Department of Biosciences at the University of Manitoba, says that the puppies look very similar, but it is difficult to know how similar they are physiological.
“They worked on 20 different mutations … The 14 genes influenced. To put this in the right perspective, a wolf probably has 22 or 23,000 different genes,” he said. “At the moment we have a 99.999 percent gray wolf with 0.001 percent worse wolf.”
Bring back the phenotypes
Shapiro acknowledges that the puppies are not exactly the same as the bad wolves from before, but the idea was to create something with the same characteristic characteristics that can lead a healthy life in modernity.
“If we think about the expansion, we do not imagine that we will reproduce something that is genetically identical with something that was alive in the past,” she told CBC News. “This is impractical and probably not what we want. Instead, we want to bring these phenotypes back, the extinct characteristics that have defined this species.”
The colossal CEO Ben Lamm says that the project started about two years ago to talk about people about wolves and save the critically endangered red wolf.
At the same time, the private company in Dallas announced on Monday that it had also produced four cloned red wolves with a new, less invasive technology that developed it while working on the direct wolves.
According to Lamm, several indigenous American communities have been interested in having reintroduced bad wolves in their country, but says that this would be a complicated process in which a comprehensive consultation with landowners, governments and other stakeholders would be necessary.
At the moment colossus, the bad puppies are examining exactly and plans to introduce them to a wild living space.
Some criticized Colossal DE Exincion projects because they have drawn attention to the less conspicuous work of organizations that are devoted to the preservation of existing species and their habitats.
Joe Walston, Head of Global Nature Conservation at Wildlife Conservation Society, estimates that De-Extincion projects can inspire people to think about the preservation of the species, and he, on the other hand, and he does not against the use of technology as an instrument for maintaining species such as Red Wolf.
But most species, he says, can recover with an “incredible speed” if their habitats are simply preserved and left alone.
“We have tiger, we have lions, we have wolves ourselves, we have the big predators that are in trouble and need our help,” he said.
“Sometimes we are too distracted by the novelty of something and forget that what we already have on earth is the most remarkable assembly of species that the world has ever seen.”
