"I very much doubt that Aquinas, or just about any of the church fathers would embrace evolutionism "

Are you saying that Aquinas, a Roman Catholic would be more likely to agree with Ken Ham, argumentative museum operator, than the current Roman Catholic Church? Possible I guess :-) For those who believe in heaven, it is more likely that he and John Paul II had a laugh or two at Ham's arguments during the debate. IMHO :-D
