Three genetically modified wolf puppies, made to look like the extinct dire wolf, were recently born and are being closely watched at a secure facility in the U.S., according to Colossal Biosciences. These puppies, now three to six months old, already weigh about 80 pounds and are expected to grow up to 140 pounds. Dire wolves, which went extinct over 10,000 years ago, were much bigger than today’s gray wolves. Scientists studied ancient DNA from fossils found in Ohio and Idaho to find the key traits of dire wolves. Using CRISPR, a gene-editing tool, they changed 20 parts of gray wolf DNA and created embryos. These embryos were then placed in domestic dogs, leading to the birth of the wolf pups. This shows how modern science can bring back some features of extinct animals. However, Professor Vincent Lynch from the University at Buffalo said it is not yet possible to fully recreate a dire wolf—only some traits. Colossal also cloned four red wolves to help endangered populations. The project was praised by the U.S. Interior Department and may help future conservation efforts.
