Both Andrew Sullivan and Kevin Drum are wrong, but I think Drum is infuriatingly wrong. The evolution statistic does have epic significance. If kids were graduating from high school unable to read or do basic arithmetic, we’d see that as a serious indictment of our educational system…and we’d be right to worry about our future as a technological society. That 46% of our citizens graduate with a complete denial of a most basic, fundamental fact about our world — that all of the sciences, not just biology, but physics, geology, chemistry, and astronomy concur that the planet is billions of years old — represents a massive failure of our educational system. In itself, it’s a small problem — it’s knowledge of one small detail. But as a symptom, it indicates a nation-wide problem.
