This is a fierce, majestic beast that disappeared thousands of years ago, with the exception of rendering artistic in books and on the screen, as in Game of Thrones.
Or maybe it's just a gray wolf with a few corrections.
The American Biotech Company Colossal Biosciences announced a surprise on Monday, claiming that he restored the tragic wolf of the dead, thus achieving the first successful “elimination” of the company.
The colossal films of a fluffy white wolf wander in their habitat with an area of 2000 acres in an undisclosed place in the northern United States, a large win for a company that also works on the revival of a woolen gam, Dodo and the Tasmanian tiger.
But some scientists say that although the existence of wolves is an impressive feat, they are not exactly as advertised.
“I want to see how some reviewed documents come out of this to better understand what was actually done, what is known and what did not do,” said Hank Greely, director of the Center for Law and Biosciency of the Stanford University.
He says that seeing puppies, smiling on his face and was a welcome surprise in another gloomy landscape of the message.
But in his opinion, creature is a more “tragic wolf”.
“I think it is important that people remember that they are not tragic wolves. There are gray wolves that have some tragic features of a wolf,” Greely said. “On the other hand, they seem to be closer to tragic wolves than anything else he saw for 13,000 years, and it's pretty cool. And they are sweet as hell.”
He used to be hunting for a big sacrifice
Large wolf species wandered both than 100,000 years before it became extinct about 13,000 years ago.
It was believed that he hunted for large victims, such as horses, bison and giant lazy, and also disappeared mainly because his victims' species expired – partly because of people hunting.
Beth Shapiro, the Chief Scientific Officer of Colossal, says that scientists have distinguished DNA from a 13,000-year-old tooth and 72,000-year-old bone from the internal ear from the tragic skull of the wolf, as well as extracted and seized DNA for the purpose of gathering genome.
They determined that the gray wolf was his closest living relative – “99.5 percent identical” in DNA, he says – and similar appearance, but larger, more muscular and with a lighter coat, a wider skull and a stronger jaw.
Then the scientists changed gray -wilk to give them the tragic features of the wolf, performing 20 editions in 14 genes before they formed embryos and implanting them into large domestic homes.
Shapiro said that three out of eight dogs used as substitute mothers gave birth to tragic wolves, and mothers were then adopted anonymously through the American society Humane – “So somewhere there are families who adopted a dog who gave birth to a tragic wolf, and they don't know.”
Colossal says that two men's puppies, Romulus and Remus, were born on October 1 – placing them now in the early stages of puberty – while Khaaleesi, a woman, was born on January 30 and is almost at the age in which you can “introduce boys” – said Shapiro.
Kevin Campbell, a professor from the Faculty of Biological Sciences of the University of Manitoba, says that while puppies look very tragic wolves, it is difficult to know how similar they are physiologically.
“They edited 20 different mutations … which influenced 14 genes. And saying that the wolf probably has 22- or 23,000 different genes,” he said. “At the moment we have 99.999 percent of the gray wolf, with 0.001 % of the tragic wolf.”
Restoring phenotypes
Shapiro admits that the puppies are not exactly the same as the tragic wolves from Jore, but says that the idea was to create something with the same characteristic features that can lead a healthy life in modern age.
“When we are thinking about distortion, we can't imagine that we will restore something that is genetically identical to something that once lived,” said CBC News. “It is impractical and probably not what we want. Instead, we want to restore these phenotypes, extinct features that defined this species.”
The colossal director of Ben Lamm says that the project began about two years ago, as a way to encourage people about wolves and save critically endangered red wolf.
On this front, a private company from Dallas also announced on Monday that it also produced four cloned red wolves using a new, less invasive technique developed while working on Dire Wolves.
Lamm claims that several local American communities have expressed interest in the re -introduction of wolves on their land, but claims that it would be a complicated process that requires extensive consultations with land owners, governments and other interested parties.
For now, Colossal is carefully studying tragic puppies and does not plan to introduce them to the wild habitat.
Some criticized the projects of Colossal's deposition for paying attention from the less flashy work performed by organizations devoted to the behavior of existing species and their habitats.
Joe Walston, head of global protection at The Wildlife Conservation Society, says that he appreciates that the deposition projects can inspire people to think about the protection of species, and is not against using technology as one tool to preserve species such as red Wolf.
But most species say, they can recover at an “unbelievable pace” if their habitats are simply preserved and left alone.
“We have tigers, we have lions, we have wolves themselves, we have these great predators that are in trouble and need our help,” he said.
“Sometimes a novelty distracts us too and we forget that what we already have on earth is the most unusual set of genre that the world has ever seen.”
