well Humans still have to adapt to the environment because of natural disasters. They can't control/change those yet.

I'm inclined to think it would take a more grievous and long term disaster than we've seen for any evolution to take place. Disasters like Katrina and the 04 tsunami just killed a shitload of people, seemingly without any rhyme or reason. I imagine that if there were an evolutionary effect of these incidents, it wouldn't be seen for hundreds of years, by which point I imagine we'll all have died out due to some other circumstance. The one thing I can see still forcing evolution of our species is global warming/pollution, which is widespread and ongoing enough for long term natural selection.
