[QUOTE]Originally posted by Antalas: [QB] [QUOTE]Originally posted by Askia_The_Great: No one is arguing "purity", certainly not me. And even if the Israel_C were not "predominantly" Natufian, they would still have significant Natufian ancestry. In fact other studies showed that Israelis from the Chalcolithic period had SIGNIFICANT ancestry that the Natufians had. As shown [URL=https://www.ncbi.nlm.nih.gov/core/lw/2.0/html/tileshop_pmc/tileshop_pmc_inline.html?title=Click%20on%20image%20to%20zoom&p=PMC3&id=6102297_41467_2018_5649_Fig3_HTML.jpg]here.[/URL] No offense, but I am having a hard time following your argument Antalas(btw that chart is from [i]Ancient DNA from Chalcolithic Israel reveals the role of population mixture in cultural transformation[/i]), as the chart shows in that study Levantine populations during the Chalcolithic period clearly had Natufian like ancestry, meanwhile this same ancestry is not being detected in huge amounts in the Horner, Kenyan/Tanzanian pastoralist or ancient Moroccans profile in large amounts compared to the dark green(which I bet $100 on is indigenous North African) from that chart in the Swahili study. The blue in the Israel_C is Natufian ancestry and I bet $100 on it. If the Israel C were not predominantly Natufian, then can you explain why that ancestry skipped a people(Israel C) who lived in the area that ancestry is from to be found predominantly in Northeast Africans? As for Neanderthals? No one denied Neanderthals were in Africa, however I said Neanderthal ancestry in Northwest Africa was most likely due to ancestry from southern Europe. Northeast Africans as far as I can remember have very little to no Neanderthal ancestry. Unless, you can point me to a study that shows such and I will be interested. And as for that Eurasian component from 30,000 years ago being absorbed? This is NOT "speculation", when a study I posted literally proposed that. Heck, the majority of studies propose this. Unless you're telling me that U6 never became localized? Either way, all in all these profiles are showing dark green and not blue like Israel C which clearly raises eyebrows. Thus far I have not seen any credible evidence/theories that dismisses the dark green as indigenous North African. [/QUOTE]Why are we even arguing ? My proposal was simply that the component could potentially be an older Eurasian component, given that migrations dating back to the Upper Paleolithic are known, and that's also what some papers, such as Hodgson et al 2014, have suggested. However, I am also open to the possibility of an African autochthonous origin, which I find interesting. As for Israel_C like I said it isn't that simple such stark contrast with the other samples can for instance be explained by genetic drift. Don't rely too heavily on it because it's likely that future papers will present new results and modeling that may change the current chart. Anyway the hypothesis that Neanderthal ancestry was mediated by WHG is not supported by archaeology, and if I recall correctly, one of Lazaridis' latest paper showed no evidence of WHG contribution to IBM.
