In a bold leap for genetic science, U.S.-based Colossal Biosciences has unveiled what it calls the first successful “de-extinction” — the birth of three genetically engineered pups carrying the traits of the long-extinct dire wolf. The company, also pursuing the resurrection of the woolly mammoth and dodo, announced the wolves’ arrival with footage from a remote U.S. habitat. Built from DNA sourced from 13,000-year-old remains, the pups were created by editing 14 genes in grey wolf cells to reflect dire wolf features before implanting them in domestic dog surrogates. While scientists agree the canines are more grey wolf than dire, Colossal says the goal is to revive ancient phenotypes for modern ecosystems. The announcement also included news of cloned red wolves using the same biotech — a nod toward real-time conservation. Critics warn such high-profile projects could overshadow urgent efforts to protect endangered species already roaming the Earth.
