But unlike the mutants, he gained the ability from a scientific serum. Gardiner, however, said humans build entire organ systems in the womb; from just some genetic information a human embryo develops into a complete person in nine months. And that is the detail which matters more than the question of whether or not Steve Rogers couldeventually heal.
