Dr. Amos has a long string of papers casting doubt that modern humans carry any appreciable admixture from Neanderthals. He has an alternative explanation which seems to fit the evidence much better. I have tried to raise these points on another forum and the experts there would not really engage. They just made vague comments about how he was mostly looking at single gene comparisons when the real evidence is in corresponding mutations in gene regions. I asked him about it and he replied with a study which showed that often times genes mutate in linkage to other genes- the study he cited had up to eight genes in a region linked in their mutations. If one mutated a certain way then the others would also mutate in a certain way. This in his mind made a hash of claims that a region containing matching mutations found in a sister species was due to introgression from that species, and I have to say that sounds reasonable. The other site would not engage on that and basically got testy. So I wonder if anyone here would like to take it on?
There seems to be a big push to try and sell Neanderthals as so much like us, I’ve seen evidence stretched to silly lengths to make that case. So papers like this one are not getting the attention that IMHO, they deserve.
