Evolution happens with 'natural selection', where animals with the strongest genes have a higher chance of breeding. Example, giraffes, they use to be horses. The ones with the longer neck gene actually lived, and thus, had a higher chance of breeding. Over time some horses evolved into giraffes, ect. This doesnt happens with humans, because people with longer necks dont have a higher chance of breeding. The only real trait that gives you a higher chance of breeding is good looks, but then again ugly people can breed with other ugly people, ect. So no, were not going to evolve.
