It’s oddly ironic how Marvel’s mutant idea doesn’t mesh with actual evolution. A random gene appearing in hundreds (and later thousands) of newborns each time manifesting itself in some way completely different?

The notion of them having superior traits is still valid, I suppose, with some exceptions. There are physically ugly mutants, some of which have fairly useless powers. Artie comes to mind (even though he’s depowered; work with me). So I guess the X-gene isn’t always a good mutation, which is just in the context of evolution because there aren’t any other traits in the world that cause both good and bad mutations (that I know of–I don’t claim to be a biologist or geneticist).

Good thing we’re dealing with fiction.
