As I mentioned before, Hox gene expression shared by lobe-finned fish and tetrapods support our relationship (which is supported by so many other lines of evidence), and the differential expression of these in ray-finned fishes supports their being a side-group not in our direct line of descent.
Now you may cling to the futile hope "Perhaps these genes will be mysteriously missing in lobe-finned fishes!" and act as though the fact that we haven't looked for them yet means evolution is false, but when we do find them I hope you won't be too disappointed.
That's incorrect. There is no "evolutionary" relationship in gene skipping. Ancient Coral share immune genes with Modern Man...for Evolutionary Theory to have a shot at potential correctness, there would have to be evidence of those same immune genes in some Fish of some Age or "branch."
But there is no such evidence. Fish don't have those immune genes now, and don't appear to have ever had them in the past...per the evidence in hand today.
Ah, how quaint. You display "hope" that one day we'll find your missing genes.
That's a nice display of blind faith, but that's not science.
Science itself, however, shows us no such immune genes in Fish.
...not in any "branch" of fish...not in Fish of any Age no matter how distant in the past one goes.
But guided by blind faith and hope, you cling to the obsolete wish that one day your pot of genetic gold will be found in Fish.
Won't happen.
