I guess it depends how you define religion. From the abstract: > We carried out two nationwide data collections that allowed us to compare differences in the acceptance of evolution in Italy and Brazil by high school students who declare to belong to the same religion in the two countries. Roman Catholic students showed significant differences between the two countries, and the gap between them was wider than between Catholics and non-Catholic Christians within Brazil. Our conclusions support those who argue that religious affiliation is not the main factor in predicting the level of evolution acceptance. My hunch is that being Catholic doesn't really mean the same thing in different countries, so the conclusion doesn't make much sense to me. Of course it's not the "religious affiliation" that matters but how the religion is practiced. I don't like the mismatch between the title and the abstract and actual study (the title mentioning religion rather than religious affiliation).
