I'm incapable of reading through genetic studies because me stupid, and as a consequence, I'm unable to confirm or contend with what's said throughout this blog. The writer seems like an extremely competent person, and even though I have no idea of their character, I feel confident thinking them above barefaced lies. I would like for someone with a brain for reading through and comprehending half-words-half-abbreviations studies to clear this particular excerpt up for me regarding our West Eurasian ancestry:
"Almarri et al. (2021) compared the DNA of ancient Egyptian individuals from the Pre-Ptolemaic era with that of the modern Afro-Asiatic-speaking populations in the Horn of Africa. Analysing single nucleotide variants (SNVs), the scientists found that their Pre-Ptolemaic Egyptian specimens provided the best-fitting model for the source of the West Eurasian ancestry borne by the Horn groups, whereas their ancient Levantine sample from Sidon appeared to have contributed most of the West Eurasian ancestry carried by the present-day Arabian and Levantine populations. These results represent a significant advancement over other genomic analyses (e.g. Razali et al. (2021)), which by contrast insisted on employing Levantine or Arabian samples as reference populations in lieu of ancient Egyptian samples. As a consequence, these studies substantially undercounted the Horn groups’ actual West Eurasian ancestry. Thanks to Almarri et al.’s better designed and more logical analysis, we can now estimate that ancient Egyptian-related ancestry is present at frequencies as high as 70% among Cushitic and Ethiosemitic-speaking individuals of the Horn, with a percentage climax in Eritrea and likely northern Somalia (cf. Table S4). (*N.B. Sirak et al. (2021) analyzed Christian-period individuals buried at Kulubnarti in Sudan, and similarly observed that “we obtain a fit only when Egypt_published is used as the West Eurasian-related proxy.” Sirak et al. (2022) also note that “ancient DNA data suggest that the African gene flow observed in present-day Egyptians occurred predominantly within the last 2000 years.”"
