Interesting hypothesis. Whenever an article like this comes around, I'm reminded how little we really know about sleep. How did it start? Why is it necessary at all? Hopefully studying the sleep of other animals will reveal some of it's mysteries. For now, though, asking "Why do we sleep?" seems like asking "Why is water wet?".

Well, there was the "washes the brain" mouse study[1] a couple of years ago, which is at least suggestive.

We are the product of our environment, a spinning rock. Conserving energy during the inevitable night cycle has been found to be more successful than fighting it.
