Well, at least as so far as concerns statements I can find from my bishop, HG Bishop Youssef, on our diocese website (http://www.suscopts.org/
), it seems that the Coptic Church at least is against both evolution and homosexuality. I don't want to put words in anyone else's mouth, though, so while I assume that you could find similar opinions expressed by bishops or other officials of the various OO churches, I don't really know for sure. I have read some Ethiopian Orthodox materials that seem to be against evolution, though.
Separate from all that, it seems like you can't go wrong by picking "an individual problem within the minds and heart of people", no matter what it is we're talking about.
