Adaptation occurs within one generation where as evolution, even on its smallest scale, only happens through heredity. I've had creationist friends that played word games where evolution didn't happen but "adaptation" did. Where if they really understood the definitions they would realize they didn't know what adaptation meant.
Most mutations are nuetral. Not helping or harming an organism, and this is one of the ways we trace common ancestors...by identifying these nuetral mutations.
As far as beneficial mutations...sickle cell anemia is sort of beneficial if you happen to live in an area where malaria is prevalent.
