[QUOTE]Originally posted by Djehuti: [QB] ^ The problem comes from what exactly is meant by "Eurasian". Because ancestral Eurasians originated in Northeast Africa, some genetic markers in that region can be confused as Eurasian back-migration. Hence why Elijah asked the question here: [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=009054]What is the true amount of authentic "Eurasian" mix in Horners?[/URL] As I've already shown [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=15;t=013416;p=2]here[/URL] [QUOTE]Originally posted by Djehuti: [qb] [QUOTE]Originally posted by Ibis: [qb] While this thread has provided me a lot of insights on Ethiopia's artistic conventions. I still have questions regarding the genetic component of Tigrayan populations. If we assume that Arabians, specifically south Arabians were phenotypically and genetically indistinguishable from SSA populations how is it that this study was able to find up to 50% non African DNA among them? I like 50% is composed of middle eastern and European populations. [IMG]https://live.staticflickr.com/65535/53030694253_fc37921278_h.jpg[/IMG] Since individual differences haven't been found amoung Tigrayan populations(unlike Oromo) isn't it safe to say that their ancestors were initially Northern/Central Asian semites that back migrated to the horn and mixed with Cushitics resulting in their African admixture? [/qb][/QUOTE]The genetic position of East Africans has been discussed many times before including [URL=http://www.egyptsearch.com/forums/Forum8/HTML/001611.html]here[/URL] in regards to the Tishkoff et al. 2000 study: [i] ..these observations support the hypothesis proposed by other nuclear-genetic studies (Tishkoff et al. 1996a, 1998a, 1998b; Kidd et al. 1998) [b]*[/b]that populations in northeastern Africa may have diverged from those in the rest of sub-Saharan Africa early in the history of modern African populations and that a subset of this northeastern-African population migrated out of Africa and populated the rest of the globe.[b]*[/b][/i] This explains much of the genetic affinities.

[IMG]https://i.imgur.com/c35rdwx.jpg[/IMG] According to the table the Wolayta are 34% 'Eurasian'. Here are some Wolayta [IMG]https://wsca.ucoz.com/_ph/1/38142681.jpg[/IMG] [IMG]https://d.ibtimes.com/en/full/1514916/festival-performers.webp?w=736&f=6f98e5cc37f7caf16a4f8badeb6e153d[/IMG] Yet according to [URL=http://ethiohelix.blogspot.com/]Ethiohelix's data[/URL] in regards to their uniparental lineages.. The Wolayta have 0% Eurasian paternal lineages [IMG]http://3.bp.blogspot.com/-3PNET-Ombu0/VXNsmKulVjI/AAAAAAAAAV0/vofqat4F7qA/s640/ETH_YDNA.png[/IMG] And whatever Eurasian maternal lineages they have does not even reach 20%. http://1.bp.blogspot.com/-BJtLrUrnzrA/VXSMaioAVXI/AAAAAAAAAWQ/10B4diOJpFc/s1600/ETH_MTDNA.png What's more is that the Dogon of West Africa look no different from other West Africans yet their autosomal data shows that they are over 60% Eurasian! [IMG]https://lastplaces.com/wp-content/uploads/2023/01/B_mali_dogon_03_casa_palabra.jpg[/IMG] So there is something more to their Eurasian affinity than mere "admixture" or back-migration.
