The Howl Returns: Dire Wolves Are No Longer Just Legends

After vanishing from the planet nearly 12,500 years ago, dire wolves have made a stunning comeback—thanks to the breakthrough work of scientists at Colossal Biosciences, a Texas-based biotech company.

Two healthy pups—Romulus and Remus—have been born through genetic engineering and ancient DNA cloning, reviving a species that once ruled North America as a top predator.

At just six months old, these dire wolves already weigh over 36 kg and stretch nearly four feet long.

Elon Musk Reacts: Wants a Pet Woolly Mammoth

Billionaire entrepreneur Elon Musk took to X (formerly Twitter) after hearing the news.
“Please make a miniature pet woolly mammoth,” Musk posted, resharing the scientific breakthrough with a sprinkle of his signature humor.

Ancient DNA, Modern Science: How They Did It

The dire wolf pups were created by using the DNA of their closest living relative—the gray wolf—along with fragments from ancient remains, including a 13,000-year-old tooth and a 72,000-year-old skull.

According to George Church, professor of genetics at Harvard and MIT and co-founder of Colossal, the cloning process used a type of blood cell with high efficiency.

“We think it’s a game changer,” he told Time Magazine.

These Pups Are Different: Wild By Nature

Though raised in a secure and monitored facility, the pups behave very differently from regular wolves. They are not affectionate and avoid human interaction, showing signs of the natural solitary instincts believed to be common in dire wolves.

Even their handler, who raised them from birth, can't get too close without them backing away.
“They want to be lonely,” one scientist remarked.

What’s Next? More Extinct Species on the Radar

Colossal isn’t stopping here. The company is working on reviving other extinct animals including the woolly mammoth, dodo, and Tasmanian tiger.

CEO Ben Lamm called this a massive breakthrough:

“This is the first of many upcoming examples proving that our de-extinction technology works.”

The revived wolves are now living on a 2,000-acre secure site protected by tall fencing, drones, and 24/7 surveillance.

FAQ

Dire wolves were large predators that roamed North America around 12,000 years ago. They likely went extinct due to climate change and competition with other species.

They are genetically engineered using ancient DNA and gray wolf DNA. While not 100% identical, they are close recreations of the extinct species.

The pups are living on a 2,000-acre secure site at a secret location in Texas, monitored with drones and camera systems.

Musk reacted humorously on X, asking scientists to create a miniature woolly mammoth, reflecting his interest in futuristic and biotech ideas.

Colossal is working on reviving the woolly mammoth, dodo bird, and Tasmanian tiger. The dire wolf is their first success.
