They say we are evolving mentally, behavior, etc. And physically, but in small ways, immunnities, etc.
Yeah, I heard a couple years ago that our pinky's getting smaller D: And yeah, every new virus finds an immunity, evolves, finds a new immunity and then you get epidemics, then SUPER MUTANTS. JK.
But, yeah, I think the mental capabilities evolving and all is something that could change humanity radically. I mean, if all our descendants become powerful psychics, maybe some long-lasting problems can finally be fixed. Who knows...
