Only 40 percent of Americans believe in evolution, according to a new study (Hat tip: Smart Christian).

University of Michigan prof Jon Miller, who led the study, attributed America’s skepticism regarding evolution to poor training in biology and a literal interpretation of the Bible by a small but vocal group of American Christians.

I would suggest some other reasons for Prof. Miller to consider:

• We Americans think independently and question everything. Until you can prove it to us — and there remains no proof of evolution — we aren’t convinced.

• Yes, many of us accept the Bible literally, and your own study demonstrates that we are not such a “small group.”
