The Appearance of Design (Ch4, The God Delusion)

Does the appearance of design mean there must be a universal Designer? In Chapter 4 of The God Delusion, Dawkins argues that not only is design explicable without a God, but complexity and design actually demonstrate that there almost certainly is no God. This episode considers Dawkins' "Ultimate 747 Argument" against God's existence, as well as his attempts to explain biological and cosmological complexity through natural processes alone.
