So to demonstrate to you, a mutation that has benefits we need to find one that has not spread to the whole population but is beneficial to those individuals who have it. Therefore we would not expect to be able to positively identify huge numbers. Moreover, gene mapping is a new science and has only just begun to examine the genes of a few species. Nevertheless there are many examples. Antibiotic resistance in bacteria and lactose tolerance in adult humans are particularly well studied examples.
you seem a reasonable fellow dave so believe me, the evidence for evolution is compelling. Even if selection/mutation is not responsible, the fact that humans and all other species have evolved from common ancestors is established beyond reasonable doubt.
I too am a layman but if you have any doubts or questions I would be glad to address them as best I can.
