Hello Tuan, First of all we cannot bar any possibilty in science amd medicine. No-one would ever think that it's possible for us to reach the moon, let alone robotic exploration of Mars!! Anyway, if there is such an evolutionary pressure, in order to survive, biological species including human have the ability to adapt to new environment. This is provided that the selective pressure is slowly evolving; an abrupt change of environment could quite likely drive us into extinction. Now, remember, evolution is a very slow process. Even if we are to change, we are talking about million of years for any noticeable change to happen. In your life-time, or certainly mine, I cannot see human "evolving" into a flying species. Nonetheless, with technology advancing so rapidly, I cannot reject the possiblity that one-day a "portable flying apparatus" (as seen in many cartoons/movies) may help us fly without being "inside" an aeroplane. Ops...I think I'd better keep my flying licence up to date then :-) I hope this helps... Joshua Chai
