If you click on this link, you find another than will give you a nice view on the subject. My understanding is that many leaders have expressed different views on the subject. Certainly the more forceful have been against it. Certainly the majority of members do not believe in it. But I am unaware of any actual binding statement that forbids believing in it or declares it true or untrue. It's really left pretty ambiguous. Actually, while people tend to feel more comfortable with definite boundaries and prescriptions, in reality much of what my church teaches is not ironclad; there is room for interpretation on a number of subjects. But don't let me mischaracterize us either. There are of course other things that are set in stone. Anyway, the subject at hand is evolution, and I am providing another link for you which includes quotes of leaders that tend to go both ways on the topic.
