Pete, what makes evolution appear to be so untestable, to you? What about breeding dogs - can't you make new breeds by selecting traits from other breeds? What makes that not a demo of evolution? What about needing a new flu shot every year? Malaria and sickle-cell, hooves and grasses, cystic fibrosis and diarhheal diseases, all demonstrate evolution, by existing here and now and changing the way they change if variables are manipulated in testing hypotheses. Moths in the UK changing color with pollution levels... there are countless demontrations of it, many of which have led to testable hypotheses, all of which, when tested, have been borne out. This why evolution is a theory, like gravity, and not an mere superstition, belief, or credo. Which *part* of evolution, precisely, do you think cannot be tested? Maybe by figuring that out we can figure out where the crux of your fundamental misunderstanding lies.
