The "amount of information in the genome" is a concept whose only purpose cast doubt on evolution, that is why it is a bad concept. The mechanism through which the random mutations become inherently useful is the process of natural selection. The refutation of the challenge is simply that random mutations do add extra information. The consequence is that in the rare case where such extra complexity is beneficial it maybe transmitted through reproduction. The existence of extra complexity isn't claimed as an inherent benefit by any sane person anywhere.
