Evolution is not a slow process. The rate depends on the intensity of the
selection pressure. Selection pressure against the appendix was mild even
before its the advent of surgery. A plague which killed of 95% of humans
would result in a massive selection event leaving a human race consisting
entirely of the 1 in 20 genetically able to resist it. For most of the
developed world human evolution has been effectively halted by modern
medicine.
And you haven't even considered artificially altering the genome.
By the way X-Men is a crap film.
