Tom English and I have posted at Panda’s Thumb a careful evaluation of William Dembski, Winston Ewert, and Robert Marks’s papers on their Active Information argument. We find that it does not show that we require a Designer in order to have an evolutionary system that finds genotypes with higher fitness. Basically, their space of “searches” is not limited to processes that have genotypes with different fitnesses — many of their “searches” can ignore fitness or even actively look for genotypes of worse fitness. Once one focuses on evolutionary searches with genotypes whose reproduction is affected by their fitnesses, one gets searches with a much greater chance of finding genotypes with higher fitnesses.
I suspect that most discussion of our argument will occur at PT — I have posted here to point to that post. If people want to discuss the matter here, I will try to comment here as well. But you can also comment at PT.
