Can animals that went extinct thousands of years ago come back to life?

By revealing two wolf pups genetically produced from the DNA of an extinct species, a private American biotech business has aroused international interest in a ground-breaking development that crosses the boundaries between science fiction and reality. The Texas-based genetic engineering firm Colossal Biosciences posted a 17-second social media video of Romeolus and Remus, two healthy, energetic wolf pups, in April 2025. These puppies are unique not just because of their mythological names but also because of their ancient genetic heritage; they were produced using DNA from the Dire Wolf, a predator that lived thousands of years ago. It is thought that the Dire Wolf vanished around 10,000 years ago, having once roamed North America during the Ice Age. Dire Wolves were bigger, stronger, and had a different biology than the gray wolves of today. Colossal Biosciences claims that these puppies are genetic hybrids made with sophisticated gene editing methods rather than straight clones. Researchers put the modified DNA into wolf embryos after reconstructing large swaths of the Dire Wolf genome. As a result, puppies may have greater morphological and genetic similarities to the old species than any contemporary dog. Colossal, which had earlier declared plans to revive the woolly mammoth, is now pushing the limits of de-extinction technology, sparking ethical discussions as well as optimism. They claim that their objective is to improve ecosystem resilience and restore lost biodiversity in addition to reviving species. There is still disagreement among experts. Critics point to unforeseen ecological repercussions and moral quandaries surrounding the revival of extinct species, while proponents hail it as a groundbreaking development in conservation biology. All eyes will be on Romeolus and Remus's growth as well as Colossal's audacious strategy of "bringing the past back to life."
