I've only found "controlled" experiments. And that makes sense, to a point.
But since 'Darwinism' is as much about environment as it is about species, I'm afraid those don't help the debate much.
But what is certain is that the 'fruit fly' experiments in no way disagree with Darwin.
Never said they did....disagree that is. The only way for us to test the ToE is to experimant. And the only way to experiment without corrupt results is in a controlled environment. Scientists have to do their best, in a controlled way, to simulate environmental selective pressures and apply them to populations which will later be compared against a control population.
