Corrected entry: In the climax, when Wolverine struggles getting towards Jean, some of the flesh on his body is ripped off by Jean's mutant power. The flesh then is quickly back by Logan's rapid healing ability. But the hair on his chest also comes back the same as it was before. This is not supposed to happen. (01:32:35)

Correction: First, this is for the wrong film. The sequence you're describing is from X-Men 3. Second, as you say, these are *mutant* powers. The very definition implies that the abilities don't conform to anything natural as we understand it.
