""Settlers may have brought in mice with the favourable gene that were able to out-compete mice with the native variant,....."

Which means no new genes evolved. This is an argument against evolution, but the Darwinists have their "Evolution Tunes" playing so loud, they read it as the opposite!

How is it an argument against evolution? It "speeds up" the process of what would happen if there was such a mutation in the gene pool of those mice, and observes what would happen after the mutation. It's not trying to observe the mutation itself, it's trying to observe the effect of such a mutation.
