Scientists revive 12,500-year-old extinct dire wolves

A Texas-based biotech company has brought dire wolves—a species extinct for about 10,000 to 12,500 years—back to life in a landmark genetic engineering project. Colossal Biosciences, known for its ambitious “de-extinction” efforts, recently announced three snowy-white dire wolf pups named Romulus, Remus, and Khaleesi, marking the first time the mythical predators have walked the Earth since the last Ice Age.
