Whilst I thought I'd get away from all the talk on Covid-19 for a while, I thought I'd read up again on The Forgotten Exodus. The into Africa Theory of Human Revolution. I saw this particular article and wondered if maybe this might go some ways to explain the "hubris" the C's mentioned. Hope this isn't noise.
After reading the article Core problem: Human Genome Project reference is based on a single person and missing millions of DNA base pairs I wondered if there might have been a bias involved in the initial selection of the material for sequencing of the human genom.:

"A letter published in Nature Genetics this week finds that the reference genome is missing a colossal 10 percent of the genetic information found in the genomes of hundreds of people with African ancestry—information that also appears in other human populations."

The articles you reference are from 2018, this month another study was published claiming to have sequenced/studied much more. Apparently in this new study African and Oceanian populations are included - or at least some of them. I posted the article earlier in this thread, you can find it here.
That said, i don't think they have things all figured out, just to note that they have made some headway in their studies since 2018. In fact, the researchers state in that very study, "However, no single DNA variation was found to be present in 100 per cent of genomes from any major geographical region while being absent from all other regions.", which, if i understand it correctly, would mean ethnic specific viruses would be very difficult indeed. Also, these studies are those that have been published, there may be more they've chosen not to or are suppressing.
