REPOST: Sudani Results W/ Improvised Fitting
This is meant to be an update on my previous post.
Okay, so I re-ran my models from a few days ago using a Global fit, and the results are noticeably better—especially for the Medieval period. The fits are tighter overall and line up well with multiple Vahaduo runs I did using my G25 coordinates.
Main Result:
Sudanese Nubians/Arabs are best modeled as a 3-way mix of:
- Medieval Nubians
- Additional Nilotic/Cushitic ancestry
- Arabian-related input
Meanwhile, Medieval Nubians themselves fall along a 2-way cline:
- Deep Nilotic (“Dinka-like”) ancestry native to Sudan/South Sudan
- An ancient Northeast African component linked to populations native to modern day Egypt
The local Northeast African component is better proxied in models using West Eurasian-related ancestry and is believed to be a Natufian-like Egyptian hunter gatherer population.
Overall, this lines up pretty well with what we’d expect historically: continuity from indigenous Nilotic populations + a Northeast African layer + later historic Arabian input.
