Dire Wolves are back after 10,000+ years of extinction

After being extinct for more than 10,000 years, Dire Wolves—yes, the hulking Ice Age predator —is making a comeback. Sort of.

Thanks to the mad geniuses at Colossal Biosciences, three genetically engineered wolf pups are now alive, thriving, and presumably howling at the moon in a secure location somewhere in the United States. The pups already weigh around 80 pounds, have long white coats, and jaws you probably wouldn’t want near your furniture. They’re expected to hit about 140 pounds once fully grown—right in line with the prehistoric units they’re modeled after.

But before you pack your bags and head for the hills, let’s get one thing clear: these aren’t actual Dire Wolves. They’re what happens when scientists get access to ancient DNA, modern technology, and zero adult supervision.

It feels like we’re playing God a bit here, right? Not saying it’s wrong to do this or that there wasn’t thought-out reasoning behind it, just doesn’t seem like something humans should be doing. But I mean, look how cute these things are.

The process behind their creation sounds like science fiction with a biology degree. Researchers studied ancient DNA from a 13,000-year-old tooth found in Ohio and a 72,000-year-old skull fragment from Idaho. Then, using CRISPR, they edited 20 specific traits into gray wolf cells, transferred that into dog egg cells, and implanted the resulting embryos into surrogate dogs. Sixty-two days later—boom: Ice Age Lite.

Colossal’s team admits that these pups will never be perfect Dire Wolves. They won’t learn to hunt like their ancestors, mostly because there aren’t any wild dire wolf packs around to teach them how to take down a mammoth. One scientist even compared them to cosplay—great costumes, missing the original vibe.

Still, it’s a major scientific leap. And while some biologists are skeptical about how useful this tech will be in the wild, Colossal sees potential beyond just bringing back prehistoric mascots. They’re also using similar methods to clone critically endangered red wolves, hoping to increase genetic diversity and prevent extinction in real-time.

As for what species might be next? The company has dropped hints about everything from woolly mammoths to dodos. Which is either exciting or deeply unsettling, depending on how you feel about the idea of a genetically resurrected Ice Age petting zoo.

So no, we don’t have true Dire Wolves roaming the plains just yet—but we do have something that looks and growls awfully close. And considering these pups started with a fossilized tooth and ended up chewing on squeaky toys, that’s a pretty wild full-circle moment.
