The dire wolves are real. They are also, depending on who you ask, not dire wolves at all.
Colossal Biosciences announced three puppies in January: Romulus, Remus, and Khaleesi, born from embryos edited across 14 genes and 20 distinct genetic variants. The DNA came from a 72,000-year-old skull and a 13,000-year-old tooth. The company called it the worlds first functionally de-extincted animals. George R. Martin, who has skin in this game as a Colossal investor, wept on a Zoom call. The internet had a moment.
Then the scientists showed up.
The three animals are grey wolves with edited traits, not dire wolves revived from true extinction. That is not a minor distinction. Beth Shapiro, Colossals own chief scientist, told MIT Technology Review the company has been upfront about this from the beginning. The three animals are merely grey wolves with 20 edits, she said. What Colossal actually built is a demonstration of simultaneous multi-gene editing at a scale the field had not seen. The company claims the work set a record for the highest number of precise genetic edits in any living vertebrate species. Whether that constitutes de-extinction is a definitional argument the scientists are already having without Colossal in the room.
Colossal reached a $10.2 billion valuation in January 2025 on a $200 million Series C led by TWG Global, making it one of the most valuable private biotechs in the country. The valuation rests almost entirely on the credibility of what the platform can do, not on what it has already done. Dire wolves are the proof of concept. The screw worm is the first real-world test case.
The New World screwworm reached northern Mexico in January. The parasite lays eggs in the living flesh of livestock and occasionally humans, and it was eradicated from North and Central America in the 1960s. Containment failed in 2024. Texas Governor Greg Abbott issued a statewide disaster declaration on January 29 to prevent its spread across the border. The threat to the cattle industry is estimated in the billions. Colossal has been working on a gene drive to stop it. The company says their approach is the only viable solution at scale.
This is where the hype-to-reality ratio gets interesting. Lamm called invasive species a $5.4 trillion problem on the podcast. He also said, in the same conversation, that invasive species measurement is incomplete. The published literature puts direct global costs at roughly $35 billion per year, which compounds to $5.4 trillion over about 154 years, not in a single year. That is a meaningful difference. Lamm frames it as an annual figure. The data does not support that reading. Flag it accordingly.
The ViaGen acquisition closed in November, and it may be the most operationally significant thing Colossal has done. ViaGen clones animals at success rates around 80%, compared to an industry average of approximately 2%. That is not a typo. Somatic cell nuclear transfer at that efficiency changes the economics of everything Colossal is building, from de-extinction demonstration projects to conservation applications for endangered species. Cloning at scale, combined with simultaneous gene editing, is the actual platform.
Colossal also launched a spinout called Breaking, which emerged from work at the Wyss Institute at Harvard in April 2024 with $10.5 million in seed funding. Breaking is engineering a microbial consortium that breaks the chemical bonds in plastic, rather than breaking plastic into smaller microplastics. X-32, their lead organism, degraded up to 90% of polyesters and polyolefins in under 22 months in lab conditions. Lamm mentioned on the podcast that he could picture a gut supplement version, though he did not say they are building one. There are roughly 5 grams of plastic in the average human brain. The problem is real. The supplement is speculative.
The pattern is consistent: Colossal announces a dramatic outcome, the scientists clarify what it actually is, and the platform underneath turns out to be more interesting than the headline. Lamm is not hiding this. He told Diamandis that two years ago the team was doing victory laps when they managed a couple of successful edits. Now they are doing hundreds at 90% efficiency and expecting to scale DNA synthesis delivery to 20 times what any published research has demonstrated. The gap between the announcement and the science is not fraud. It is the normal lag between what a company says it is building and what the field will eventually verify.
The question for anyone watching this space is not whether dire wolves are back. They are not, not in any genetically pure sense. The question is whether the platform works at the scale Colossal claims. The screw worm emergency will answer that before any academic paper does.
