Does complexity require intelligent design?

Sure. Easy. Frst tell us which particular definition of "information" you are using, so we can select an appropriate example of it increasing.Of course, there are case known where one mutatin does some change, and another independent mutatiuon un-does that change. Did both those mutations decrease information?

Sorry, not usefual good enough.You said "The barrier is that no new genetic information can be produced by mutation". In order to evaluate that claim we need a way to measure the amount of information, so we can compare it before and after a mutation to see it it has increased or no;, or a way to characterize information as "new" or "old" and then characterize the information present before and after a mutation to see if any of the information after the mutation is "new".So, to be meaningful your defintion of information must include either a way to measure the quantity of information at any time and/or separate arbitrary information into "new" and "old" categories.Of course, you wouldn't have made that claim without having made the appropriate measurements and/or determinations, or at least knowing a reference to someone who has ... would you?

Still waiting for a reply to Message 202. Whan combined with selection, absolutely. It's downright dishonest to claim to understand evolution and then characterize it as you do, ignoring selection. Ignoring the effect of selection, therefore not germane. Oh, there are literally thousands of examples. Just a few:Antenna design (e.g. Unnatural Selection, Genetic Hybrid Antenna Fills the Gap).Web page layout (Not-So-Mad Science: Genetic Algorithms and Web Page Design for Marketers).Scheduling (buses, the Traveling Salesman problem, ...) (e.g. Genetic Algorithms vs. Blind Search, Resource Scheduling with Distributed Genetic Objects).Electronic circuit desing (CREATURES FROM PRIMORDIAL SILICON, Radio emerges from the electronic soup, An evolved cirduit, intrinsic in silicon, entwined with physics).A list of several more: Some specific examples of GAs.

It's possible that any definition you give will not satisfy me, but you certainly haven't tried yet. You made a claim which relies on you having a definition of information which can be used to make measurements. You failed to respond to the part in which I pointed out why your definition wasn't useful or good enough. Here it is again:You said "The barrier is that no new genetic information can be produced by mutation". In order to evaluate that claim we need a way to measure the amount of information, so we can compare it before and after a mutation to see it it has increased or not; or a way to characterize information as "new" or "old" and then characterize the information present before and after a mutation to see if any of the information after the mutation is "new".So, to be meaningful your definition of information must include either a way to measure the quantity of information at any time and/or separate arbitrary information into "new" and "old" categories.You cannot have any basis for your original claim unless you already have a definition of information which meets one of those two criteria. So, which is it; did you have no basis for your claim, or do you have such a definition of information all ready to type ou?
