Scientists create wolf pups that resemble extinct dire wolves using genetic engineering.
Scientists at Colossal Biosciences have created three genetically engineered wolf pups that resemble extinct dire wolves.
The pups, aged three to six months, have white hair, muscular jaws, and weigh around 80 pounds, expected to reach 140 pounds at maturity.
Researchers used ancient dire wolf DNA to modify blood cells from a living gray wolf with CRISPR technology, then transferred the modified cells to a domestic dog egg and surrogate.
While the pups physically resemble dire wolves, they won't learn to hunt like their extinct counterparts.
The company also cloned four red wolves to increase genetic diversity in the endangered population.
