  28. An ecosystem The ecological theater The evolutionary drama

  29. But, how can “random” processes design complex structures?

  30. But, how can “random” processes design complex structures? Isn’t this like expecting a bunch of monkeys locked in a room with typewriters to eventually type out Hamlet’s soliloquy? Actually one monkey with a computer could do it -- if it were arranged like natural selection
