I was reading <i>Time</i> magazine of August 15 of this year. I was curious about the fact about what would happen if natural selection is proved wrong? Then if it is proved wrong, is our understanding of the reality relative? And if it is relative, how are we sure that the way we understand our surroundings is the correct one? I really need you to answer this question because I am afraid of devoting my life to something that later will prove completely wrong. Thanks.
