It's worth remembering that the idea of evolution predates Charles Darwin and, to some extent, biology. The idea of biological evolution was first suggested by Erasmus Darwin, grandfather of Charles, in 1794. It was probably a reflection of the metaphysical concept of progress which was born in the 18th century and dominated the 19th. For the 19th century, everything evolved: society, language, science, the natural world. It just so happened that biology was the one area where the theory actually worked, although many philosophically-naive intellectuals cherish the concept to this day.
It's also misleading to think that evolution has been opposed by "priests/ministers/imams". In both Christianity and Islam, Creationism is confined to fundamentalists and the uneducated (not exclusive categories, or course!)
