Video Shows 1st Dire Wolf Howl in 10,000 Years
A company says it has brought the dire wolf back from extinction and posted videos showing the two animals.
Colossal Biosciences posted a video to its X site showing the dire wolf pups howling. The video had 13 million views in less than 24 hours.
"SOUND ON. You’re hearing the first howl of a dire wolf in over 10,000 years. Meet Romulus and Remus—the world’s first de-extinct animals, born on October 1, 2024. The dire wolf has been extinct for over 10,000 years," the company wrote along with the video.
"These two wolves were brought back from extinction using genetic edits derived from a complete dire wolf genome, meticulously reconstructed by Colossal from ancient DNA found in fossils dating back 11,500 and 72,000 years," the company noted.

"This moment marks not only a milestone for us as a company but also a leap forward for science, conservation, and humanity," according to Colossal.
"From the beginning, our goal has been clear: 'To revolutionize history and be the first company to use CRISPR technology successfully in the de-extinction of previously lost species,'" the company wrote. "By achieving this, we continue to push forward our broader mission on—accepting humanity’s duty to restore Earth to a healthier state. But this isn’t just our moment—it’s one for science, our planet, and humankind. All of which we love and are passionate about. Now, close your eyes and listen to that howl once more. Think about what this means for all of us."
The company has shared other videos of the dire wolves on its X page. The company also has videos on its YouTube page explaining how it says it revived the dire wolf.
