[QUOTE]Originally posted by Archeopteryx: [QB] As I mentioned before there is also this abstract by Scheunemann et al who was presented in 2021: Urban, Christian; Neukamm, Judith; Eppenberger, Patrick; Brändle, Martin; Rühli, Frank and Schuenemann Verena, 2021: [b]Human mitochondrial haplogroups and ancient DNA preservation across Egyptian history[/b] At the same conference also an abstract about Nubia from Meroitic time up until c AD 1450 was presented. Scheunemann was involved in that study too. I have not seen that study published yet (?) [QUOTE]The kingdoms of Nubia, located in the Nile River Valley of modern-day northern Sudan and southern Egypt, served as an important corridor of migration for millennia. Little is known of the ancient genetic landscape, but this biological perspective can further our understanding of population movements before this event. Here, we created a time-transect of genetic diversity in the Middle Nile region, using whole mitochondrial (MT) genome analysis of ancient DNA samples obtained from several archaeological sites spanning nearly two thousand years, from the Meroitic period (ca. 350 BCE) to before the Arab expansion (ca. 1450 CE). We trialed 43 individuals, extracting DNA using newly developed 8, including petrosal bone extraction, nonheat sample processing, enzymatic pretreatments, and DNA capture techniques, optimized for samples with very poor DNA preservation. Following strict contamination and authentication assessments, we retrieved whole mitogenomes for six individuals: two with African ancestry and four with Eurasian ancestry. The ancient Nubians showed most genetic affinity with modern East Africans, Middle Easterners, and Egyptians. These results indicate that Nubians had a strong African component with evidence of gene flow from Eurasia dating back to at least Meroitic through Christian times. Although these individuals ncompass varying archaeological contexts and span two millennia, these initial results hint at the complexity of the region's genetic makeup and begin to reconstruct the impact of migrations from outside Africa. Lastly, our work represents the first successful retrieval of full MT sequence data from Middle Nile inhabitants, further demonstrating the viability of paleogenomic work in Sudan.[/QUOTE]Scheunemann et al 2021: [b]Paleogenomic insights into Nubian ancestry from ancient Middle Nile populations[/b] [URL=https://isba9.sciencesconf.org/data/pages/Abstract_Book_ISBA9_2022.pdf]Link to the abstracts[/URL] Both abstracts were presented at the ISBA9 9th International Symposium on Biomolecular Archaeology, June 1st – 4th 2021 (Toulouse, FRANCE) [/QB][/QUOTE]
