Resurrected Dire Wolves’ Size Doubles in Groundbreaking Revival Captured on New Footage
Scientists Revive Dire Wolves: Genetically Engineered Pups Thrive

Made famous by Game of Thrones, dire wolves—extinct for over 12,000 years—have been brought back through genetic engineering. Texas-based Colossal Biosciences, known for pioneering "de-extinction" projects like woolly mammoths and dodos, has successfully created the first hybrid dire wolf pups: Romulus, Remus, and Khaleesi.
Growing Giants
In a recent update, the six-month-old male pups now weigh over 90 pounds each—20% larger than average gray wolves—making them the closest approximation of their ancient counterparts in millennia. Khaleesi, born in January, is smaller at 35 pounds but still 10-15% bigger than typical gray wolf females. The team monitors her growth before introducing her to the males.

Science Behind the Revival
Colossal compared ancient dire wolf DNA from fossils to gray wolves, identifying 14 key genes. Using CRISPR technology, they edited gray wolf embryos to express these traits, such as increased size and bone density. While not exact clones (true de-extinction requires preserved DNA, which is unavailable), the hybrids represent a breakthrough. The pups were carried by surrogate wolves and raised in controlled environments.
Behavior and Social Dynamics

Footage shows the pups thriving socially. Remus exhibits alpha traits—strategic and observant—while Romulus, though larger, follows as a beta. Khaleesi’s integration is gradual, with fence-line introductions to ensure safety. The trio eventually aims to form a functional pack on a private preserve.
Ethical and Ecological Concerns
Experts like Dr. Nic Rawlence warn of risks: hybrid wolves could disrupt ecosystems if released. Historically, dire wolves hunted larger prey, and their modern counterparts might do the same. While Colossal plans controlled habitats, unintended gene flow into wild populations remains a concern.

Looking Ahead
Dire wolves once roamed North America, weighing up to 150 pounds. Colossal’s team believes their growth trajectory could near these ancient specs. The project underscores ambitions to reverse human-driven extinction, though debates about ethics and ecology persist.
Final Note
These pups symbolize a leap in genetic science—but whether they’ll roam wild or remain curiosities hinges on balancing innovation with caution.
