Non-Random and Cumulative Nature

Steven Novella on attempts to dispute evolution from the perspective of Information Theory.
Scientists do not claim that random processes can create information. Evolution is not a random process. There are two components to evolutionary effects on information: mutations and recombination increase the amount of information in a random manner, and then natural selection provides for non-random survival of that variation. These processes, working in tandem, can explain both the increase in the amount of genetic information over time and the non-random and cumulative nature of that information.
It never hurts to restate this kind of thing. The "how can a 747 just assemble itself in a junkyard?" argument still keeps popping up.
