"Brought back" is a hell of a stretch. It sounds like they've heavily edited wolf dna to try and match fragments recovered. I wouldn't be surprised at all if they're sterile. I don't want to take away from the achievement, which is truly exciting for the field of genetics, but these headlines aren't exactly telling the correct story.
