Scientists revive dire wolf species from ‘Game of Thrones’ in world’s first known ‘de-extinction’ - The dire wolf — a species that disappeared 13,000 years ago and was made famous by the beloved HBO series “Game of Thrones” — is making a comeback, thanks to the first-ever so-called “de-extinction.” Three dire wolf pups — aptly named Romulus, Remus and Khaleesi — were successfully born using DNA from ancient dire wolf fossils and genes from their closest living relative, the gray wolf.

The extraordinary results were revealed Monday by Colossal Biosciences, the same Texas-based genetic engineering company that created the adorable colossal woolly mouse.

“Our team took DNA from a 13,000-year-old tooth and a 72,000-year-old skull and made healthy dire wolf puppies,” said Colossal CEO Ben Lamm. “It was once said, ‘any sufficiently advanced technology is indistinguishable from magic.’ Today, our team gets to unveil some of the magic they are working on and its broader impact on conservation.”

To create the cute pups, Colossal cloned high-quality cell lines using somatic cell nuclear transfer into donor egg cells, and transferred them to a surrogate dog mom, who gave birth in January, according to the statement.

The ancient DNA was taken from a tooth fossil found in Ohio that is around 13,000 years old and an inner ear bone from Idaho, about 72,000 years old.

The two six-month-old male wolves, Romulus and Remus, and female pup Khaleesi now reside in 2,000- plus acre “secure expansive ecological preserve” with 10 full-time staff to give them round-the-clock care, Colossal said.

Dire wolves have appeared in HBO’s “Game of Thrones” and George R.R. Martin’s fantasy series which the TV show is based on, “A Song of Ice and Fire.” In the show, the wolves are the sigil, or mascot, of House Stark.

Khaleesi is also named after the character, Daenerys Targaryen, played by Emilia Clarke in the series.

Despite their fictional significance, dire wolves were real-world predators that lurked across North America with mastodons and saber tooth tigers during the Ice Age. They hunted horses, bison and possibly mammoths, paleontologist Julie Meachen told the New York Times.

After many of those prey became extinct due to human hunters, the dire wolf went extinct, and the gray wolf filled the “ecological void,” Meachen said.

Dire wolves are 25% larger than their gray wolf counterparts, with more muscular jaws and shoulders, biologists say.

Lamm and George Church, a Harvard Medical School biologist, founded the now $10 billion private company with the goal of bringing back the woolly mammoth, Bloomberg reported.

The company also has its eyes set on reviving the Tasmanian tiger, the dodo, and successfully genetically engineered the woolly mouse last month, which shares similar curly-haired features with woolly mammoths.

00:00We turn now to that remarkable scientific breakthrough.
00:0213,000 years after the last dire wolf walked the earth,
00:06scientists say they've now brought them back.
00:10Tonight, a howl 13,000 years in the making.
00:15In a first for science, biotech company Colosal Biosciences says
00:19it brought the extinct dire wolf back to life,
00:22a species that hasn't walked the earth since the Stone Age.
00:25The dire wolf is the first extinct species.
00:28Well known from HBO's hit show Game of Thrones.
00:34Now seven months old, dire wolves Romulus and Remus
00:37eating well and getting bigger every day.
00:40ABC News given exclusive access into Colosal's lab in Dallas
00:44where scientists are using genes from gray wolves to create dire wolves.
00:50That animal looks like a dire wolf.
00:52It will behave like a dire wolf and it is a dire wolf.
00:55We've taken a gray wolf genome, a gray wolf cell,
00:59which is already genetically 99.5% identical to dire wolves.
01:04And we've edited those cells at multiple places in its DNA sequence
01:09to contain the dire wolf version of the DNA.
01:13And David, the company tells us they're not stopping there.
01:15They plan to have woolly mammoths roaming the earth again by 2028.
01:18But critics argue that this de-extinction could harm fragile ecosystems.
01:24The end of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day of the day
