More ignorant than blind, I think. I was under the impression that, had anyone successfully demonstrated macroevolution in the laboratory, surely the proof would have been trotted out for everyone to see. Then again, I confess that I don't subscribe to a single peer-review journal, so I suppose I can't blame anyone for that but myself.
So if I may ask, what experiments have been done, and what were the results? Could you point me to some resources?
