Dire Wolves Return: First Extinct Animal Resurrected by Scientists
So, imagine this—something straight out of science fiction just became reality. The dire wolf, a legendary predator that vanished around 12,500 years ago, has officially made a comeback. And no, this isn’t a scene from Game of Thrones . This is real life. Scientists from Colossal Biosciences, a company based in Dallas, have actually resurrected three living dire wolf pups using cutting-edge genetic technology. Let me walk you through how they pulled off this mind-blowing feat.
The team began by gathering ancient DNA from fossils—one a tooth dated around 13,000 years old, and another from a skull believed to be about 72,000 years old. Using that ancient DNA, they were able to assemble full dire wolf genomes and compare them to modern canids like gray wolves and foxes. With those comparisons, they pinpointed the genetic traits that defined dire wolves—like thick white fur, broader skulls, and more powerful jaws.

Using CRISPR gene editing, they then tweaked gray wolf DNA to closely match that of dire wolves—editing 20 gene sections across 14 genes. The modified cells were used to clone embryos, which were implanted into surrogate domestic dogs—large mixed-breed hounds, to be exact. The result? Two male pups were born in October 2024, and a female pup followed in January 2025.
Now, while these pups are genetically about 99.9% gray wolf, they carry signature dire wolf traits, giving them that iconic prehistoric look. Scientists call them hybrids, but what they’ve really recreated is the phenotype —the physical expression of the dire wolf’s genes. And that’s a monumental first in the world of de-extinction.
They’re currently being raised at a secret, secure, 2,000-acre facility surrounded by zoo-grade fencing and under constant monitoring. Certified by the American Humane Society and registered with the USDA, the site ensures the pups are being looked after with the highest standards of care.
Colossal says this breakthrough not only demonstrates their technology can bring back extinct animals, but it could also aid conservation efforts. For example, they’ve already used this process to clone critically endangered red wolves with improved efficiency. Still, it raises a lot of questions—ethical ones, ecological ones. Critics argue the money could be better spent protecting existing wildlife. Others wonder whether these creatures, no matter how genetically accurate, could or should be released into modern ecosystems.
Even so, this achievement marks an enormous leap forward in synthetic biology. And while some may argue over whether these are "true" dire wolves, what’s undeniable is that we’re now living in a world where extinction doesn’t necessarily mean forever. Wild, right?
