De-Extinct Dire Wolves Ready To Breed; Bioscience Company Pushes Forward Multiple Projects
Authored by Steve Watson via Modernity.news, Colossal Biosciences has announced that its de-extinct dire wolves—Romulus, Remus, and Khaleesi—are now breeding-aged and the firm plans to expand the pack later this year. The development marks a significant step for the Texas-based company in its mission to restore extinct species through genetic engineering. The dire wolf pups, born in late 2024 and early 2025, represent the world’s first de-extinct animals. They have thrived in a secure 2,000-acre preserve, reaching milestones like learning to process whole deer carcasses and now showing readiness for natural breeding behaviors. “The dire wolf pack is actually breeding-aged at this point,” Matt James, Colossal’s chief animal officer, said, adding “But we will initially grow the pack through assisted reproduction while we create new, genetically diverse individuals.” The company intends to engineer two to four additional pups to boost genetic diversity before allowing full natural breeding. “The plan is to create an inter-breedable population of dire wolves in which they would eventually breed naturally to create a sustainable population of the world’s first de-extinct species,” James …
