Dawkins and the Extent One Will (or Must) Go to Defend Darwinism

In his article Why Darwin matters, Richard Dawkins states: "You can pare Darwin's big idea down to a single sentence (again, this is a modern way of putting it, not quite Darwin's): 'Given sufficient time, the non-random survival of hereditary entities (which occasionally miscopy) will generate complexity, diversity, beauty, and AN ILLUSION of design SO PERSUASIVE that it is ALMOST IMPOSSIBLE TO DISTINGUISH FROM DELIBERATE INTELLIGENT DESIGN.'"
