Can random mutations cause an increase in information in the genome?

It is worth pointing out that Dembski uses improbability as his measure of "complexity".Identifying something as having "specified complexity" requires showing that it would be very improbably that it could evolve, sicne the relevant probability includes evolution. Thus by Dembski's very definition evolution cannot be expected to produce this sort of "specified complexity" (and if it could then Dembski's arguments would be wrong)Dembski has found no way of usefully applying this idea to any biological feature thought to have evolved, and thus it cannot be used as an argument against evolution. Until it is possible to solve this problem it is a non-issue.
