That Homo Sapien Sapiens will never evolve. I mean, we've evolved to hold prejudice against our own kind, and according to our good friend Mr.Darwin, evolution by natural selection favors the small mutations that appear in an organism. That's a problem because in our society nobody is gonna want to mate with the mutated fellow over there, so he dies out even if he was better adapted to the current world. The contrary to that is that the mutation least suited for the current world could live on and reproduce due to modern medicine. So don't expect any flying humans or orbs of pure energy any time soon unless we change our views...according to my humble theory which isn't meant to insult anyone in any way and if it does I'm sorry
Voilà , another thought I had while taking a shower.
