Are we to credit an unguided evolutionary process for the gift of sleeping and waking? Or are these intricate systems further evidence of design? On this ID The Future, host Andrew McDiarmid concludes his conversation with Dr. Eric Hedin on the intelligent design of sleep. In Part 2, the pair dig deeper into the purpose of sleep and why it’s so essential to living organisms. They also look at why it’s unlikely that a gradual Darwinian process can be credited for the origin of sleeping and waking, and why intelligent design is a better explanation. This is Part 2 of a two-part discussion.
