Bump this thread in about 15 million years…
Stan Lee was right, the mutant invasion is upon us!
Hopefully they’ll have cool superpowers.
And see it locked by a mod for being a zombie in… oh, about 15 miliseconds. 
Locked by a mutant mod.
Personally, I welcome our new mutant, cool-power-having Overlords.
As I understand it, the Y chromosome is being constantly replaced anyway. The X chromosomes evolve a means of suppressing it, more and more females are born, then a mutant Y appears that happens to be immune to whatever Y suppression technique has been evolved by the Xs. Since the male(s) bearing that mutation are the only ones who can breed with the “Y - proof” females, their version of the Y rapidly takes over the species. Then, some millenia later ( or more ) it happens all over again.
I assume it could happen that a “Y - less” male as mentioned in the article could do the same, but I expect the odds are low simply because there are so few of them. It seems more likely to me than some man with a Y will happen to have the right mutation first, due to sheer numbers.
