The dire wolf is 鈥渢he world鈥檚 first successfully de-extincted animal鈥�, Colossal Biosciences claimed on 7 April. And many people seemed to believe it. New 杏吧原创 was one of the few media outlets to reject the claim, pointing out that the animals created by Colossal are just grey wolves with a few gene edits.
Now, in a subsequent interview, Colossal鈥檚 chief scientist Beth Shapiro appears to agree. 鈥淚t鈥檚 not possible to bring something back that is identical to a species that used to be alive. Our animals are grey wolves with 20 edits that are cloned,鈥� she tells New 杏吧原创. 鈥淎nd we鈥檝e said that from the very beginning. Colloquially, they鈥檙e calling them dire wolves and that makes people angry.鈥�
at the University of Oxford says this is a major departure from what Colossal has said previously. 鈥淚 read that as a clear statement of her view of what they did and didn鈥檛 do 鈥� and that what they didn鈥檛 do was bring back a dire wolf from extinction.鈥�

鈥淚 think there is a serious inconsistency between the contents of the statement and the actions and publicity material 鈥� including the standard content of the website, not just [the] press briefing around the dire wolf 鈥� of the company,鈥� he says.
For instance, the Colossal press release refers to them as 鈥渄ire wolves鈥� throughout. Shapiro defended this claim in an interview with New 杏吧原创 on 7 April.
鈥淲e are using the morphological species concept and saying, if they look like this animal, then they are the animal,鈥� she said at the time.
It is actually unclear whether the gene-edited wolves look like dire wolves. For instance, there is some evidence dire wolves had reddish rather than white coats, according to at the University of Oxford.
Yet even when Sillero and other experts put out a statement saying the gene-edited grey wolves aren鈥檛 dire wolves, the company stuck to its guns. 鈥淸W]e stand by our decision to refer to Romulus, Remus, and Khaleesi colloquially as dire wolves,鈥� Colossal said in .
But in her more recent interview with New 杏吧原创, Shapiro claims Colossal made it clear from the start that the animals are just gene-edited grey wolves.
鈥淲e didn鈥檛 ever hide that that鈥檚 what it was. People were mad because we were calling them dire wolves,鈥� she says. 鈥淭hen they say to us, but they鈥檙e just grey wolves with 20 edits. But the point is we said that from the beginning. They鈥檙e grey wolves with 20 edits.鈥�
Shapiro also sought to distance Colossal from suggestions that if de-extinction is possible, less needs to be done to save endangered species 鈥� a view . 鈥淣ow it鈥檚 suddenly tied to this idea that we don鈥檛 have to care. It鈥檚 terrible,鈥� she says.
鈥淭he keyword here is 鈥榮uddenly鈥�,鈥� says Grenyer. He says it has long been understood that if people start thinking de-extinction is possible, it might reduce support for conservation efforts. Colossal should be aware of this and yet, Grenyer points out, its : 鈥淓xtinction is a colossal problem facing the world鈥� The solution is de-extinction.鈥�
While Colossal is making significant scientific advances, that claim is simply wrong, says Grenyer. 鈥淚t is transformative, and it is breakthrough science 鈥� it鈥檚 just not de-extinction,鈥� he says.
Responding to this story after publication, a Colossal spokesperson says: 鈥淚n our press release, we stated we made 20 gene edits to grey wolf cells. Grey wolves are the closest living relative to the dire wolves, as we showed in our paper. With those edits, we have brought back the dire wolf. We have been using the concept of functional de-extinction from the beginning, and that is what Colossal achieved. Those are the facts and nothing has changed.鈥�
鈥淲e have also said that species are ultimately a human construct and that other scientists have a right to disagree and call them whatever they want to call them. Khaleesi, Romulus and Remus are the first dire wolves to walk the Earth in 12,000 years,鈥� says the spokesperson.
