My kid said that they are just hybrid with a tiny bit of Dire DNA. I don’t know, but she holds a Masters in genetics.
She is correct.
They are actually Gray Wolves with a few genetic traits replaced with the recovered Dire Wolf DNA, such as the white coat.
It remains to be seen if they will actually become the full size of an adult Dire Wolf which approached 200 pounds and near four feet at the shoulders.
But for now, they are an interesting curiosity experiment that possibly might be of some scientific interest...................
