Not to derail the thread about this weird research outcome with Christian Nubians, but I made the Toubou fella with the uniparental I posted recently get G25 cords. MY quick modeling told me he was mostly Nilo Saharan with minor West African (totally ~68% SSA), and the rest North African, preferring pristine Early Neolithic and Late Neolithic MAR proxies over modern population with some minor Tunisian on scaled. With unscaled, I got a nice fit, but instead of Tunisian, it was Levantine Middle-Late Bronze Age and no West African. I used all the Sudanese samples in this one.
