I would agree. At least somewhat.
One of the biggest influences on a person's acceptance of evolution is their religion. We suggest that a person's religion has 'blinded' them on a fairly regular basis around here, for instance (how many atheists question it?). Some people feel that compromising their religion will lead to the whole house of cards coming down. It isn't necessarily so, but nevertheless...
One of leading factors in atheism is educational attainment (strong correlation with a rise in education and a decline in belief). Furthermore - one of the leading professions for atheism is biology, though I don't have the exact figures to hand.
So what's going on?
Clearly education in general shifts people towards atheism. This could arise from learning to ask pressing questions, becoming more critical etc. But biology as a leading factor? I'm sure seeing the failings of the human body and horrific diseases might convince some medicine students that the problem of evil is a biggie. But I think evolution, the cornerstone of biology, really is a factor an order of magnitude at least stronger that other equally common things.
Otherwise, it would help to explain an alternative for specifically what caused the rise of atheism in the late 19th century and the 20th century.
Two massive brutal and bloody wars? The transistor? Expanded travel and communications? The rise of the media? The 1960s? (When atheism started it's rise) Vietnam? To be honest - that period was so revolutionary socially, economically as well as intellectually we can't rule out the sheer shock of it all was itself a factor.
