The sampled Ancient Egyptians are from Lower to Middle Egypt... That's the first thing.
Secondly, the dynasties that were sampled (New Kingdom to Ptolemaic) makes a big difference. Even those who carried out the results clearly mentioned that it wasn't representative so I don't see why you're trying so hard to convince us otherwise.
This is the sample you guys keep quoting as evidence:
Khairat R, Ball M, Chang CC, Bianucci R, Nerlich AG, Trautmann M, Ismail S, Shanab GM, Karim AM, Gad YZ, Pusch CM (August 2013). "First insights into the metagenome of Egyptian mummies using next-generation sequencing". Journal of Applied Genetics. 54(3): 309–25.
They mention themselves that it is NOT a representative sample and should not be seen as that. Interesting most people who quote this study are white supremacists and you guys on Somalispot.
