Dire Wolf Pups Cloned from Ancient DNA in De-extinction Breakthrough
Dire wolves, the long-extinct canines popularized by the television series Game of Thrones, have been resurrected in a groundbreaking scientific achievement. Scientists have successfully cloned three dire wolf pups utilizing gene-editing techniques and ancient DNA. This significant development, hailed as a “massive milestone” by researchers, marks substantial progress in the burgeoning field of de-extinction and wildlife conservation efforts.
Colossal Biosciences Announces Dire Wolf Revival
Colossal Biosciences, a Texas-based biotechnology company, announced on Monday the successful cloning of dire wolves. Researchers employed cloning technology and gene modification, drawing upon two ancient dire wolf DNA samples to produce three healthy pups. The litter includes two six-month-old males, christened Romulus and Remus, and a three-month-old female named Khaleesi. Colossal CEO Ben Lamm expressed immense pride in his team, emphasizing this accomplishment as a pivotal step. “I could not be more proud of the team,” Lamm stated. “This massive milestone is the first of many coming examples demonstrating that our end-to-end de-extinction technology stack works.”
Utilizing Millennia-Old Genetic Material
“Our team extracted DNA from a 13,000-year-old tooth and a 72,000-year-old skull and successfully created healthy dire wolf puppies,” Colossal scientists explained. The company highlighted the technological advancement inherent in this process, referencing the adage that sufficiently advanced technology is often perceived as magic. “It was once said, ‘any sufficiently advanced technology is indistinguishable from magic’. Today, our team gets to unveil some of the magic they are working on and its broader impact on conservation,” they added.
The De-extinction Process Explained
Experts at Colossal detailed the intricate de-extinction procedure. The process commenced with obtaining blood cells from a living grey wolf, the closest extant relative of the dire wolf. These cells underwent genetic modification at 20 distinct locations. The modified genetic material was then introduced into an egg cell harvested from a domestic dog. Subsequently, the resulting embryos were implanted into surrogate mothers for gestation, culminating in the successful births.
Dire Wolves in Popular Culture and Conservation
Dire wolves hold a prominent position in popular culture fantasy realms, featuring in role-playing games, such as Dungeons & Dragons, and video games like World of Warcraft. However, their popularization surged with the HBO adaptation of George RR Martin’s Game of Thrones novels.

George RR Martin’s Perspective
Mr. Martin, an investor and cultural advisor for Colossal, offered his insights. “Many people view dire wolves as mythical creatures that only exist in a fantasy world, but in reality, they have a rich history of contributing to the American ecosystem,” he stated. Martin lauded the company’s achievement, drawing a parallel between his fictional work and Colossal’s real-world breakthrough. “I get the luxury to write about magic, but Ben and Colossal have created magic by bringing these majestic beasts back to our world.”
Red Wolf Cloning Initiative
In a parallel announcement, Colossal revealed the cloning of four red wolves, utilizing blood samples acquired from wild members of the critically endangered red wolf population in the southeastern United States. This effort is aimed at bolstering the genetic diversity within the limited captive red wolf population. Scientists are actively breeding these wolves in an attempt to rescue the species from extinction. In previous statements, Mr. Lamm, Colossal’s co-founder and CEO, had indicated that this project represented years of dedicated work.
“Just the Beginning” of De-extinction Efforts
Lamm emphasized the significance of these births, stating, “It’s one of the most exciting and technically complicated things we’ve ever done. These are not just theoretical animals anymore — they’re living, breathing pups. And this is just the beginning.”
Pups Described as “Thriving”
Colossal’s chief animal officer, Mike Goodwin, confirmed the pups are in excellent health. “They’re strong, social, and they exhibit exactly the kind of behavioural traits we were hoping for — curious, confident and pack-oriented,” Goodwin remarked. “We’re keeping them in a highly controlled environment and monitoring their development closely. So far, all signs are positive.”
Reintroducing Ice Age Predators
Mr. Lamm concluded by underscoring the historical context of this achievement and its future implications. “People have been dreaming about bringing extinct species back for decades. Now we’ve done it — and with one of the most iconic predators of the Ice Age.”
