Bringing Back Dire Wolves: The Effort to Revive an Extinct Species.

A company made three wolf pups. These pups look like the old, gone dire wolves. The pups have white hair and strong jaws. They are getting big fast.

Scientists used old wolf bones to learn about dire wolves. Then, they changed the genes of gray wolves. They put the changed genes into dog eggs. The pups were born from these eggs.

The pups might look like dire wolves. But they won't act like them. They won't know how to hunt big animals because they didn't learn from dire wolf parents.

The company also cloned red wolves. This helps add different genes to the red wolf group. This cloning way is easier than other ways. But it still needs blood from wild wolves.

The company talked to the government about the wolf project. Some people are happy about the work, but others are not. Some say the wolves can't do the same job as before because things have changed.
