Several scientists, including me, pointed out that Colossal Bioscience’s “dire wolves” were nothing like the extinct animals for which they were named, but only grey wolves with a few gene edits taken from ancient sequenced dire-wolf genomes.
Here’s a succinct summary from Wikipedia of the mishigass about this canid: (see also here); I’ve removed the numbered references for ease of reading, but they’re in the article:
In April 2025, it was announced that Colossal Biosciences used cloning and gene-editing to birth three genetically modified wolf pups, six-month-old males Romulus and Remus and two-month-old female Khaleesi. In-house scientists made 20 edits to 14 key genes in gray wolf EPC cells to match those genes from the dire wolf in order to recreate distinctive dire wolf traits. Colossal stated that these minor genetic modifications effectively revive dire wolves as a species. No ancient dire wolf DNA was actually spliced into the gray wolf’s genome.
Independent experts disagreed with the Colossal Biosciences’ claim that these animals are revived dire wolves, asserting that they are “not a dire wolf under any definition of a species ever”.[128][129] The IUCN Species Survival Commission Canid Specialist Group officially declared that the three animals are neither dire wolves nor proxies of the dire wolves based on the IUCN SSC guiding principles on creating proxies of extinct species for conservation benefit. They commented that creating phenotypic proxies does not change the conservation status of an extinct species and may instead threaten the extant species such as gray wolves, and therefore concluded that the Colossal Biosciences’ project “does not contribute to conservation.”[130] Colossal Biosciences released a clarifying document Alignment of Colossal’s Dire Wolf De-Extinction Project with IUCN SSC Guiding Principles in response.
In May 2025, the company’s chief scientist Beth Shapiro stated that the three animals are “grey wolves with 20 edits” as purportedly stated by the company “from the very beginning”, acknowledging that it is impossible to bring back an extinct organism, or at least an organism “identical to a species that used to be alive”. She stated that the term “dire wolves” applied to the pups are a colloquialism. This was called a “major departure from what Colossal had said previously”.
One thing that people (including Wikipedia) do get wrong is how many edits in the gray wolf actually were derived from the dire wolf genome. It was 15, not 20. The rest were mutations known in domestic dogs and gray wolves that, thought Colossal Biosciences, would make the gray wolf resemble what they thought the dire wolf looked like. As I wrote earlier:
There were indeed 20 edits in the gray wolf genome, made in 14 genes, but five of those edits weren’t taken from the ancient DNA of the dire wolf; they were taken from mutations in dogs and gray wolves that resembled what Colossal thought dire wolves looked like. (We’re still not sure.) And among those five dog/wolf mutants were the color alleles that turned the faux wolves white.
Remember, nobody’s seen a real dire wolf, only its skeleton. The idea that they were white seems to me ludicrous, as no wolves are white. Colossal engineered light coat-color mutations into gray wolves because the dire wolves in the show Game of Thrones were white. Scientists believe that the ancient dire solves were either gray or reddish brown; white ones would have stuck out like sore thumbs to predators—except in canids, like Arctic Foxes, that live in the snow.
But does the public know this? I doubt it. And if they knew it, would they care? I doubt that, too. People like Paris Hilton, who have invested big bucks into Colossal’s dubious “de-extinction” projects, don’t care: they just want something that Colossal calls a dire wolf, just as other investors want a tweaked, hairy Asian elephant that Colossal—if it ever produces one—would call a “de-extincted woolly mammoth.” Although Colossal’s head scientist Beth Shapiro finally admitted that Colossal didn’t really made dire wolves, she later backtracked, saying this according to the May 11 NYT:
The resulting animals [the gene-edited wolves] were larger and fluffier and lighter in color than other gray wolves. The company’s chief science officer, Beth Shapiro, says this is enough to make them dire wolves, if you subscribe to the “morphological species concept,” which defines a species by its appearance. “Species concepts are human classification systems,” she told New Scientist, “and everybody can disagree and everyone can be right.”
Yep, according to Colossal, if you look even slightly like a dire wolf, you ARE a dire wolf. But this “capitalistic species concept” hasn’t fooled biologists except apparently those in the pay of Colossal. And it smacks of the woke-ish tendency to change the meaning of words if they buttress your well being (or your funding).
But I digress. Yesterday I got a puff email from Colossal celebrating the first birthday of two of the edited gray wolves, and the company is STILL calling them dire wolves. It even came with a special, albeit dreadful, birthday song. You must hear it! But first let’s see the email’s text, which I’ve pasted in below.
Note that they affirm that the two tweaked gray wolves were indeed “the first dire wolves to walk the Earth in over 10,000 years.” That is of course dceply misleading, since the three creatures produced are not dire wolves like the ones from 10,000 years ago. They are modern grey wolves with a few genetic edits. And if their story is a “banner of hope,” well, I find that misleading, too, since truly “de-extincting” a species has not only not been done, but will likely never be done. Nor is it something that many conservationists want to be done since the ancient animals would have to be put in an environment in which they didn’t evolve, and without the genes for behavior that allowed them to survive in ancient environments.
Here:
Here’s the song on YouTube. Be sure to listen to the “guitar crunching riffs, amazing solos, and sticky melodies” (what is a “sticky melody”?) produced by 80s “rock god” Stan Bush. I don’t know Bush, or whether he really has the status of a “rock god,” but I’ll let Rick Beato pronounce on that.
Here’s the four-minuite birthday song!
Did you like that? I didn’t. The music is anodyne, with lame rhymes that remind me of a substandard version of “Eye of the Tiger.” Plus, as far as I know, the newly created dire wolves are not allowed to hunt. And “nothing to stop you”? They are kept in a fenced enclosure hidden from all but a few guests and, perhaps, investors. (You can see the fences that stop them in the video.) They will likely never be set free in any ecosystem except Colossal’s fenced enclosure.
And here’s the Instagram post with the same song:


Well, no publicity is bad publicity.
But cringe it does induce. I would actually take a bet Rick Beato will check this out!
I like that point – a person like Paris Hilton just likes the idea that some big alchemical black box of science – that they somehow control – pooped out a living animal that is sort of like the animal in Game of Thrones .. (which I did not know)…as in, “Woowwwww, far out, the ultimate power in the universe …” .. I can detect a New Age religious vibe in this …
Again, I am reminded of this superb book :
Fantasyland
Kurt Andersen
2017 (I think..)
And, just a cautionary note : there likely is George Soros’ reflexive alchemy in play behind all this. See his book Alchemy of Finance.
They have spam filters for that.
That’s where the sticky melodies come from — the spam on their hands.¹
. . . . .
¹ Or maybe it’s something other than spam….
Interesting they picked white for the dire wolf due to the show Game of Thrones as the other 6 wolves shown (including the dead mother) were all shades of grey.
Not a Dire Wolf.
A trans wolf is a WOLF! And dire is DIRE! It says so… uh, here?
So, do they plan to create a sustainable and viable population of ‘dire wolves’? They could only do so if they gene-edited a whole bunch of unrelated wolf embryos and then let the resulting ‘dire wolves’ reproduce with each other. Are they doing that? If not, that sort of reveals that this is just an attention- and money-making gimmick.
Also, one wonders if the offspring of a ‘dire wolf’ x ‘dire wolf’ mating would look like the parents or if they would start to revert to looking like regular wolves – which is what they are.
No, they are not doing that.
A dire horse.

Thanks, Mike, for the fine picture of the dire Equid. It
would be helpful to learn what species it identifies with, and, of course, what pronouns it prefers.
Neigh, nee, nigh. Or Pfft, pff, pfft.
That song is….dire.
Thanks for bringing this to our attention.
Wiki says: “not a dire wolf under any definition of a species ever”.[128][129]
If only Wiki applied the same scientific scrutiny (and honesty) to claims that “trans women are women” or that gender identity exists.
Maybe the wolves should detransition. Possibly a smart lawyer could sue on behalf of the wolves.
Yes Michael. What if one of the “wolves” hits puberty and starts to identify as a schnauzer? What’ll THAT do to the stock price I wonder…..

I thought that some wolves in the far north do have more or less white coats(?) (subspecies arctos). Seems like the genes for a white coat are likely present in Canis lupus.
Jim Brandenburg named a book of his photos White Wolf.
Arctic wolves are a subspecies of grey wolves in the far north wolf that are white year-round, but are born much darker. Real dire wolves did not live in the tundra. And yes, I’m sure you could breed a species of grey wolf that was white by selection, or you could put in white dog mutations, as Colossal did. Again, the DIRE WOLF WAS PROBABLY NOT WHITE, and there is no evidence that it was. Given its habitat, the probability is that it was darker. Further, the white coat color put into this creature came from DOGS, not wolves. They had to use a dog gene, which is telling. Dogs, of course, can be almost any color you want as there is plenty of genetic variation (green, blue, and similar colors, of course, don’t occur).
Since Colossal hasn’t (and probably won’t) publish the dire wolf sequence, we have no idea what its own genes involved in color might say. They might already know what color is may have been.
Can we not look forward to dyer wolves in green, blue,
or even plaid? A new project for Colossal, perhaps, after
they have brought back the mammoth, the dodo, and the 8-track tape.
“Dyer wolf.” I “literally” LOLed.
Thanks! Full agreement on not a Dire Wolf.
I only learned about Collossal’s misrepresentation here on your site. 🙂
Also humorous that they took their Dire Wolf coat color from a TV show!
Good grief! I only made it about one minute through the song. Very derivative and I’m another one who hasn’t heard of that particular “rock god”.
Heh. The song should be this one:
As I mentioned before – re my experience in venture capital – the longer we observe these frauds the more this company exposes itself as an investment scheme than a serious scientific endeavor. I think many believe it is a serious “science/biology play” when it is really just Jurassic Park for the stockmarket, IPO sphere.

I prefer this version!

A source informs me that there were actually five dire Colossal BS pups, 4 males and 1 female, but “Dubious” and “Doofus” died shortly after birth, of embarrassment.
“There are some things even a wolf won’t do”.
Who is Stan Bush? A one-hit wonder, who needs money.
🙄
I never heard of Stan Bush. Rock God? The song is dire, corny lyrics.
