Startup Colossal has announced de-extinction โ three "puppies" of the dire wolf have been born: Romulus, Remus, and Khaleesi. This is the result of large-scale DNA editing using CRISPR โ scientists took ancient samples (up to 72,000 years old) and integrated genome fragments into the cells of a gray wolf.
The result is not the original species, but a hybrid: a functional analogue created from a modern wolf with parts of the dire wolf's DNA. This approach has sparked controversy. Critics remind us that dire wolves are not just large wolves, but a separate evolutionary line incompatible with modern surrogates. Even with perfect DNA, it wouldnโt be a "resynthesis of the species."
Nevertheless, the achievement is significant: over 20 point mutations in 14 genes, restoring traits โ from fur to body size. Colossal calls this a "functionally equivalent species" โ a biological reconstruction without claiming full identity.
The main question now is not about science, but about intentions. Is this Jurassic Park or a step towards saving endangered species?
