Colossal Biosciences announced the successful de-extinction of the dire wolf, a species that vanished 13,000 years ago, by cloning three healthy pups named Romulus, Remus, and Khaleesi. Using ancient DNA from fossils and genes from the gray wolf, the company executed the cloning process via somatic cell nuclear transfer into dog egg cells. The pups are now cared for in a secure ecological preserve. This groundbreaking achievement reflects advancements in genetic technology and raises discussions on conservation and species revival.
Our team took DNA from a 13,000-year-old tooth and a 72,000-year-old skull and made healthy dire wolf puppies. It was once said, 'any sufficiently advanced technology is indistinguishable from magic.' Today, our team gets to unveil some of the magic they are working on and its broader impact on conservation.
The ancient DNA was taken from a tooth fossil found in Ohio that is around 13,000 years old and an inner ear bone from Idaho, about 72,000 years old.
