A Texas-based biotechnology company has successfully revived the long-extinct dire wolf, marking the world's first de-extinction of a vertebrate species. The company also cloned red wolves, the most endangered wolf species in the world. The dire wolf pups were created using ancient DNA sequencing, genomic reconstruction, gene editing, and interspecies cloning. The company's long-term objective is to reintroduce de-extinct species into protected natural habitats.
