Yeah, the X-Gene wxas designed by the Celestial in the earliest days of humanity and implanted it into the human genome, that's why many humans suddenly turn mutants and develop powers out of the blue. The gene only becomes active in a very small minority of individuals and remains dormant in the others, hence why mutants are comparatively very rare. But it remains present in the entirely of humankind, so despite all the "endangered species" theme going around for decade, they kind will live on as long as humanity. And if someone were to find a reliable activation catalyst, mankind as a whole could quickly transform into global mutantkind.
