So how about a nice rousing chorus of "Don't know much about history?"
And you should get off your condescending, ethnocentric high horse for a moment, and remind yourself that whatever you think about tribalism and cultural progress, or the potential benefit of unleashing an imagined genius weighed against the nearly certain destruction of a culture and decimation of a population by disease, it does not even remotely resemble "evolutionary development." Those fellows with the spears and bows are just as evolved as we are, and they have as much right to live their way as anyone anywhere has and we're not their gods, whatever you might imagine they think when they see us fly over.
