In this case I think the hierarchies are being a moderating force in
all hierarchical churches, as they are not acting dogmatically
regarding to science (now - they did in the past, as we all know).
Instead in the acephallous Protestant enviroment, where the Bible is
seen as only guide, many people tend to be acritical with the content
of the text and favors a rigid interpretation.
Of course, there are also Catholic fundamentalists and many many
moderate and open minded protestants but, in the USA, the role of
tele-preachers of more than dubious intent has become a force in
itself, that is not controlled by anything but probably money and
power.
This doesn't mean that hierarchical churches are inmune to that. It
probably depends on other factors, such as culture and public opinion -
though, of course, hierarchies are less prone to change easily.
In any case it is a very worrying trend. I just read yesterday that
only 48% of Britons believe that the theory of evolution is correct and
the percentage of creationists was surprisingly high for Europe:
