The survival by adaptation of the bacteria species was not an operant in the lab conditions. It was cultured to change and mutate until some beneficial mutation surfaced. The adaptation itself was a natural mutation. The culturing only gives a very supportive environment for the bacteria. Even within such a supportive environment a very maladaptive mutation will be selected out because the bacteria that don't have the maladaptive mutation will out compete the "mutants". It isn't evidence of the sort that would utterly refute the claim made in the argument against evolution that I was talking about, its just another piece of evidence against that argument. Its not the type of argument that would be simply utterly refuted/falsified, because the arguer can claim that its some other type of complex adaptation (perhaps a much more complex one, or perhaps an adaptation involving large structures in multi-cellular organisms rather than in the biochemistry of single celled organisms) supposedly can't happen. For every step you can show can happen there is a further step that they can retreat to, or at least that they will be able to retreat to for some time.
