Against the claim that Darwin only challenged orthodox religious explanations, I pointed out that many historians and commentators on Darwin argue the contrary: namely, that Darwin’s work, Origin of the Species, faced a variety of resistance, only part of which stemmed from religious doctrine. Undeniably, Darwin challenged orthodox religious accounts of life on earth (origin and maintenance); and religious doctrine was a big factor in the thinking of most people. But more importantly to the history of biological science, Darwin’s evolutionary science also challenged prevailing theories and beliefs of secular scientists and other people who did not base their views on religion at all. The idea of fixity of life species was a far broader idea than just something gotten from religious doctrine.
Today, the mega-theme of biological evolution is securely tied by literally thousands of lines of evidence anchoring it to virtually every other area of human knowledge. Thus it would appear to be the height of scientific ignorance, stubbornness and/or religious blindness to reject evolution just because it sounds too impossible, or because it’s personally distasteful, or because it conflicts with a literal reading of one specific ancient creation story. One might just as well reject gravity.
