In a stunning scientific breakthrough, researchers at Colossal Biosciences, a Texas-based biotechnology company, have successfully cloned a species of ancient dire wolves (Aenocyon dirus), a fearsome predator that roamed North America over 12,500 years ago. This marks one of the most significant achievements in de-extinction science to date.
The team extracted viable DNA from a 13,000-year-old tooth and a 72,000-year-old skull, combining advanced genetic engineering techniques to recreate the species in the modern world. As a result, three healthy dire wolf pups have been born, genetically matching their Ice Age ancestors.
Dire wolves were once apex predators, larger and more robust than modern grey wolves, with stronger jaws, broader skulls, and thicker fur. They became extinct around the end of the last Ice Age, but their legend lived on—especially as inspiration for the terrifying creatures in the popular TV series Game of Thrones.
The cloned pups are now housed in a highly secure, undisclosed 2,000-acre location. The area is protected with high fencing, 24/7 drone surveillance, and CCTV monitoring. This level of security reflects both the scientific value of the animals and the ethical considerations surrounding their existence.
Founded in 2021 by entrepreneur Ben Lamm and Harvard geneticist George Church, Colossal Biosciences has raised over $435 million in funding. The company’s mission is ambitious: not only to revive extinct species like the dire wolf, but also to bring back woolly mammoths and the dodo bird by 2028.
While the cloning success is being hailed as a revolutionary step in biotechnology, it has also sparked ethical debates. Environmentalists and scientists question the potential consequences of reintroducing extinct species into ecosystems that have long since adapted to their absence.
Nonetheless, the revival of the dire wolf stands as a monumental moment—one that blurs the lines between science fiction and reality.
