"Individual variation [in nature] was an inconvenience, embarrassment to the theory, or ignored, like a kind of "noise" that some even thought Satan introduced into God's Plan, a disruptive chaos. But Darwin and others brought the chaos of variation to center stage. No longer was this chaos considered a fallibility of "earthly life," but became "real" and not just "noise" or "interference." It became the very underpinning of the Theory of Evolution."
- Philip Marsh in "Evolution, Christians and Setians"
