“Bad Idea”: People React To Dire Wolves Brought Back To Life 10,000 Years After They Went Extinct
Science has once again pushed the boundaries of possibility—this time, by reviving a creature that vanished over 10,000 years ago.
A team of researchers has successfully brought the dire wolf back from extinction, reintroducing a lost apex predator that last walked the Earth long before the rise of modern civilization.
The breakthrough comes from Colossal Biosciences, a biotech company that has engineered three living dire wolf puppies—effectively restoring a species whose genetic lineage was thought to be lost forever.
Highlights
- Scientists resurrected the extinct dire wolf, which vanished more than 10,000 years ago.
- Biotech company Colossal Biosciences announced that it created three dire wolf puppies.
- Pups Romulus and Remus are now 6 months old, while their sister Khaleesi is 2 months old.
- The extinct dire wolf also famously appeared in the hit series Game of Thrones.

Three dire wolf puppies—six-month-olds Romulus and Remus, and their sister, two-month-old Khaleesi—were created by using ancient DNA, cloning and gene-editing technology.
The species once roamed wild and free in North and South America, leaving behind plenty of remains to tell the story of their lost legacy.

Scientists from the leading genetics company used their DNA to decipher their genome. They then altered the cells of gray wolves—the closest living relative to the dire wolf—to match their genetic code.
Through gene editing, the company modified the traits of the living gray wolves to the point where they matched that of the extinct species.
“Our team took DNA from a 13,000-year-old tooth and a 72,000-year-old skull and made healthy dire wolf puppies,” Colossal co-founder and CEO Ben Lamm said in a statement Monday, April 7.

Scientists made about 20 edits in 14 genes in the common gray wolf.
After making the edits, they cloned the most promising cell lines and transferred them into donor eggs.
“Healthy developing embryos were then transferred into surrogates for interspecies gestation,” the company said.

As for the gestation, scientists used domestic dogs as surrogate mothers to give birth to Romulus, Remus, and Khaleesi.
The genetic edits led to Romulus and Remus having a host of different physical traits, like their snowy white coats and differences in howling and whining.
Romulus and Remus are also larger, with wider heads, bigger teeth and jaws, and more powerful shoulders and muscle-packed legs.

At six months, the two male pups are already 4 feet long and weigh 80 lbs.
They could grow to measure 6 feet and weigh 150 lbs.
Colossal, which kept the dire wolf project a secret until April, revealed in March that it had successfully copied mammoth DNA to create a woolly mouse.
It was “really our first validation,” Beth Shapiro, chief science officer of the Dallas-based company, told People about the small, shaggy creature.

While there was never any prehistoric or historic woolly mouse, the company said the new woolly mice took them one step closer towards bringing back woolly mammoths.
The company opted to go with mice instead of elephants, the closest living relative to the woolly mammoth, because the elephants have a much longer gestation period.
Along with the woolly mammoth, Colossal also hopes to de-extinct the dodo and the Tasmanian tiger.

While the woolly mouse was a small step in genetic engineering, reviving dire wolves is a much bigger leap in Colossal’s de-extinction efforts.
The news of reviving extinct species left many excited, but others believe there are serious risks involved.

Cloning and gene-editing are fairly nascent fields of science, and several issues, such as organ defects, lack of immunity, and premature aging, have been observed in cloned animals.
Moreover, scientists have noticed that the introduction of new species can adversely affect other animals. For instance, in Australia, a species of toad that was introduced to kill beetles ended up poisoning the marsupials that normally eat that toad.

Cloning also carries significant risks, including potential side effects and even fatal consequences for the surrogate mother carrying the cloned embryo.

“Dragons next? Let me know,” one commenter said. “Could use a few.”

“I’m waiting for the woolly mammoth to make a come back,” another wrote.
“This is a bad idea, Jurassic Park explains it,” read a third comment, while a fourth wrote, “it may have gone extinct for a good reason.”
“This won’t turn out well,” a person said.
“Make me a tiny pet dinosaur,” one social media user said

“My issue with genetic mutation like this and bringing back extinct species like this (not ones caused by human involvement) is that there’s natural selection for a reason, and bringing species that have long since been extinct can cause further harm to our environment,” another said.
“Wasting time and resources. I’m all for balance in nature but this doesn’t seem to be the way forward,” another opinion read.
The news about the dire wolves sparked heated discussions online

This is completely inaccurate. They have NOT been brought back. Try reading New Scientist instead of the Daily Fail for the truth.

Yep. Plus, when you've got sentences like "Scientists made 20 genetic edits to 14 genes of gray wolves to match the traits of the lost dire wolf" - then no, you have NOT "brought back" the dire wolf. You've edited a gray wolf to sort of look like what this particular bioengineering group's IMAGINATION thinks that a dire wolf looks like. Dire wolves weren't even in the same "canis" genus as modern wolves (Canis lupus). You literally cannot start with a gray wolf "genetic canvas" and claim you've recreated the dire wolf. Dire wolves are in the same taxon as gray wolves, like all canines are, but they are NOT "Canis". A true "dire wolf" would probably look more like a mishmash of a hyena and a wolf, physically speaking, than these three wolves look.

The dire wolf isn't even in the same genus as the gray wolf. They're both in the same taxon ("canini") but dire wolves were NOT wolves by any means. Wolves are members of the genus "Canis", as are domestic dogs. Dire wolves were members of the genus "Aenocyon". Taking the genetic "canvas" of a gray wolf and making edits to it to "recreate" the dire wolf is literally impossible. All Colossal Biosciences did was say "This is what we IMAGINE what a dire wolf might look like!" and then spent a ton of money modifying wolf DNA to make a large, white wolf. Ironically, true dire wolves were probably NOT white-furred, as they lived in a plains/grassland/scrubland environment - they would stand out like sore thumbs if they had white fur. They were heavier-boned and had comparatively shorter legs than modern wolves, and structurally would probably look more like a hyena-wolf crossbreed than they would look like a modern wolf. Colossal Biosciences made Ghost the Dire Wolf from Game of Thrones.

I thought it was weird they were white. I was wondering why.

Let’s pretend they did bring back a species from extinction; once you open that door, when do you close it? How long until rich people are making pets from extinct animals in order to show off their money. We don’t need “more dystopian”
