Colossal Biosciences Revives Dire Wolf, First Successful De-Extinction

Colossal Biosciences has achieved a significant milestone in de-extinction by successfully reviving the dire wolf, a species that has been extinct for over 12,500 years. The company announced the birth of three healthy pups, named Romulus, Remus, and Khaleesi, using DNA extracted from ancient fossils. This breakthrough is touted as the world's first successful de-extinction, with Colossal's CEO Ben Lamm emphasizing the potential impact on conservation efforts. The company used advanced gene-editing techniques, performing 20 precision edits to integrate ancient gene variants into the genome of a gray wolf, its closest living relative. In addition to the dire wolves, Colossal has cloned endangered red wolves and plans to revive the woolly mammoth by 2028. The project has attracted investments from high-profile figures, including athletes and sports team owners, who support the mission of bringing extinct species back to life.
