Although the results of the survey do seem to suggest people in the UK are not up to modern standards regarding biological sciences, they also suggest in the most powerful way that the people in the UK still have a thriving CLASS SYSTEM.
Traditionally the lower classes there do not need to believe the ideas propounded by the upper classes. Sometimes you'll run into a working class guy who can elaborate on that thought for hours, if not days. Try Hyde Park ~ they show up there quite regularly.
My own thought on the results here are that lower class folks in UK probably should never be surveyed about upper class shibboliths.
If this keeps up, the human race will have to reinvent fire and the wheel.
