The dire wolf, an animal that has been extinct for over 10,000 years has nearly come back after scientists at Colossal Biosciences were able to edit the DNA of a more modern wolf to appear and have the features of the dire wolf, a type of wolf that was made famous by “Game of Thrones.”
Colossal Biosciences posted to X with a video clip of two small wolf cubs barking, “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.”
Watch:

“The dire wolf has been extinct for over 10,000 years. 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 between 11,500 and 72,000 years.
