[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by capra: [qb] Well, it needs a conversion factor. A recent estimate of an average 1.5% Neanderthal ancestry in Han Chinese might be a good representative of the proportion of Neanderthal in 0% Basal Eurasian populations. So that would suggest that the Medieval Iranian is maybe around half a percent more African than her putative Steppe ancestors. [/qb][/QUOTE]A couple of things to keep in mind here. 1) Estimates of Neanderthal ancestry differ depending on the paper and sometimes even depending on the analyses used in the same paper. The figures are not compatible across papers. Does the analysis you're using give the Neanderthal % of the Iran_Recent sample? 2) 0.5% more Neanderthal in Han compared to Iran_recent does not translate to 0.5% more African ancestry in Iran_recent, if that is what you mean. Going by your figure of 1.5% in Han, 0.5% less Neanderthal would correspond to ~33% extra African ancestry in the Iran_recent sample 3) While the Han Neanderthal % initially seemed to be a good proxy of pure Eurasian ancestry, this is now no longer the case. For instance Eurasian HGs have Neanderthal proportions ranging from ~10-2%. Han Chinese are on the lower end of the range. Meaning, their Neanderthal % also decreased over time 4) It's not just Basal Eurasian that decreased the Neanderthal in Iran_recent and other Eurasians. Bronze Age Semitic speakers for instance also spread recent Sub-Saharan ancestry. This ancestry also would have reached Iran. [/QB][/QUOTE]
