Point taken, what I meant to refer to technically the process of Natural Selection as a means/process of Evolution, and yes you are correct variation is technically the right term. I do believe the theories and studies of Natural Selection are valid and useful.
Nobody really has a problem with natural selection either. The selection process, though, is a gaurd against drastic major change. It is Quality control. Quality control doesn't turn Microwaves into helicopters. It ensures quality microwaves and nothing but. That is not unique to big "E" evolution either. So, nothing you reference makes evolution anything useful to science..
