Colossal Biosciences has successfully reintroduced the dire wolf, a species that went extinct approximately 12,000 years ago. The company's innovative approach involved extracting DNA from ancient fossils and combining it with the genetic code of the gray wolf, its closest living relative. Three dire wolf pups, named Romulus, Remus, and Khaleesi, have been born and are currently thriving in a secure ecological preserve. This landmark achievement signifies a major scientific breakthrough in de-extinction efforts, building on Colossal's previous work, including the creation of genetically engineered 'woolly mice.'
Our team took DNA from a 13,000-year-old tooth and a 72,000-year-old skull and made healthy dire wolf puppies.
Together, this data provided more than 500x more coverage of the dire wolf genome than was available previously.
