Many of today’s Egyptians are not necessarily representative of Ancients due to outside migration and admixture from European/Arab sources, particularly in Lower Egypt.
Some Coptic claims to be pharanoic descendants not supported by DNA studies or cultural history showing heavy Arabization since 900 ADModern Copt genetic profile shows substantial Middle Eastern and European elements.
Modern Egyptian population not necessarily representative of the ancients
"Cosmopolitan northern Egypt is less likely to have a population representative of the core indigenous
population of the most ancient times“
– Keita 2005. History in Africa, 2005, 32(1).221-246
"Outside influence and admixture with extraregional groups primarily occurred in Lower Egypt—perhaps during
the later dynastic, but especially in Ptolmaic and Roman times (also Irish, 2006).”
