[QUOTE]Originally posted by the lioness,: [QB] [QUOTE]Originally posted by Swenet: [qb] Yes, he might have gems on other topics, but I've never seen him say anything useful about Africans when it comes to common Eurocentric tropes. He always panders to his armchair anthro audience. They all say non sense like this: [QUOTE]So what about the Sardinian admixture from Africans? The same dynamic might be at play here: [b]old admixture from “Early European Farmers” into Africans might explain why they’re closer to Africans.[/b][/QUOTE]But what does that even mean? Llorente et al 2015's [URL=https://www.ncbi.nlm.nih.gov/pubmed/26912899]wild claims have been corrected by the authors[/URL] and these pinheads are still gloating over "massive Eurasian ancestry" in Sub-Saharan Africa that "pulls southern Europeans to Africans". Where is this "massive farmer input" that they keep talking about? Notice how he tries to emphasize that the farmer ancestry he's talking about is "old". That's often their excuse why they can't post anything official: the farmer ancestry deep inside Sub-Saharan Africa is supposedly "old" and somehow requires "special equipment" to detect. This is simply pseudo science. This claim cannot be disproved because it's not falsifiable. It's deliberately not falsifiable. That's how they protect their worldview of not being a hybrid population. ANI is also partly Basal Eurasian so you can see how certain positions Razib takes are driven by denial. [/qb][/QUOTE]You are missing the point of the thread topic quote by leaving the rest of it out [QUOTE] But let’s assume that the Sardinian admixture from Africans is legitimate. What does that mean for estimates of ancestral derivation from continental populations than you see in the DTC personal genomics firms that report ancestry results? It can only mean that among people of Southern European ancestry a few percent of African ancestry is being “masked” because it is part of the reference population set. This came to my mind because a half Cuban friend of mine had ~2% African ancestry. Reasonable. When I checked by running unsupervised ADMIXTURE he had ~4%. Then I noticed that the Sardinian reference set was often in the 1-2% range. One explanation for the discrepancy then would be that a few percent of African ancestry in his genome was simply swallowed up by the reference population in the supervised learning framework. [/QUOTE] [QUOTE]Originally posted by BlessedbyHorus: However, I am skeptical of the author as the name "Razid Khan" sounds familiar. [/QUOTE]then you should have a critique of the conclusion here [/QB][/QUOTE]
