Evolution happens every day in the viral world. You know how virii and germs gain "immunity" to things?
Where do you think new viruses and flus come from? You think Spanish flu came out of nowhere?
Look, I'll level with you. Evolution is 100% proven to occur. However, the only thing we cannot prove is that humans specifically evolved. We can look at evolution and look at the fossil trail and say, "there is a 99% chance that humans resulted form evolutionary processes".
So while we cannot prove humans evolved for sure, we know empirically that evolution exists. Until further scientific discoveries are made, in the way of gene change, that will be the only thing christians can say against evolution, which boils down to "there is a 1% chance that science is wrong about human evolution".
When the discovery finally is made, expect conspiracy theorists for the next millenia.
