[QUOTE]Originally posted by Elijah The Tishbite: [QB] [QUOTE]Originally posted by Antalas: [qb] [QUOTE]Originally posted by Elijah The Tishbite: [/qb]This study is from 2014 as well and none of the Horners approach 40% Eurasian: https://www.nature.com/articles/srep06055 Check Supplementary Table 1 Afar 10.5% Arabian Ethiopia Jews 13.6 Arabian Ethiopian Amhara 14.7 Arabian Ethiopian Oromo 5.1 Arabian Ethiopian Somali 0% Arabian Ethiopian Tigray 16.3 Arabian/Levantine Caucasian 6.1% Oromo 10.3% Arabian Tygray 14.4% Arabian Wolayta 6.1% Arabian Also from the study: [i]The Amhara, Oromo and Wolayta samples from Ethiopia had Lowland East Cushitic, Nilo-Saharan, Omotic and Arabian ancestry and the Tygray sample also had a small amount of Levantine-Caucasian ancestry (Supplementary Table 1). These samples of Ethiopians had no Niger-Congo or European ancestry (Supplementary Table 1). These results indicate that the YRI and CEU samples are not optimal choices as proxies for the parental populations of Ethiopians. [b]Furthermore, these Ethiopian samples have four or five ancestries and therefore should not be modeled by two-way admixture.[/b] As with the Mozabite sample, use of the YRI and CEU samples as proxies for the parental populations for the Ethiopians will lead to reconstruction of excessively short haplotypes, estimation of excessively long times since admixture began and poor estimates of admixture proportions.[/i] [/QB][/QUOTE]You just contradicted yourself : Why are you simplifying West Eurasian ancestry as merely "Arabian"? Even the quote you referenced acknowledges that multiple proxies are necessary to accurately model them. Seems like you are not even aware of the fact that multiple waves of Eurasian migration occurred at different periods in the Horn of Africa. [/QB][/QUOTE]I guess you can't read, the 4 or 5 ancestries that Ethiopians and Somalis have according to THAT study in 2014 are Lowland eastern Cushitic, Nilo-Saharan, Omotic, Arabian, and in the case of the Tigray only, Levantine Caucasian. That 30-50% Eurasian figure is way overstated and what "multiple waves" of Eurasians migrated into the Horn? There's no evidence of that. Some of what these geneticists are calling "Eurasian" is no doubt shared common ancestry from the African population that spawned OOA migrations as noted here below: [i]Hence in conclusion we argue that the X-chromosome evidence presented here shows a genetic continuity ranging from Sub-Saharan Africa, through North-Eastern Africa, into the Near East. [b]However, the reduction in Tn diversity does suggest that a population bottleneck occurred in Ethiopia, associated with a major out of Africa expansion(s), which parallels the conclusion made by Tishkoff et al. (1996) from analysis of the CD4 locus. Certainly our data are not incompatible with the argument from Tishkoff et al. (1996) that an element of the contempo-rary Ethiopian population may be descendants of the ancestral population that spawned the migration out of Africa.[/b] We also argue, however, that in addition to this early bottleneck event, later periods of admixture have played a major role in shaping the gene pool of Ethiopia, and its populations display both Eurasian and Sub-Saharan genetic influences. While these results are from the analysis of just one locus, and samples sizes for a number of populations remain relatively small (particularly in the case of the Oromo and the Ethiopian Jews), we feel that in association with data from other marker systems they add a complemen-tary perspective to the history of Ethiopia and her peoples.[/i] Ethiopia: between Sub-Saharan Africa and Western Eurasia There is no doubt that Horners have Eurasian mixture, just not to the tune of 38-50%.
