Charles Darwin fleshed out the Theory of Natural Selection (the most important to science).

He also wrote on the Origin of Man (the most important to religious people).

Copernicus never had a negative relationship with the Church because his theories were not published until after he died. His books were largely ignored by the Church and did not even acknowledge it until almost a century after it was published. There wasn't much controversy surrounding Copernicus.
