The article, the topic and the entire post is purely about “Did the Arab Conquest Replace the Ancient Egyptians? The Myth of Population Replacement”
Specifically about Egyptians. Not about Libyans, Syrians, Saudis leave alone about Europe or the Americas
A recent international study found that modern Egyptians share more ancestry with sub-Saharan Africans than ancient Egyptians did,
whereas ancient Egyptians were found to be most closely related to ancient people from the Middle East and Western Asia.
This DNA analysis indicates that Population Replacement has come and gone before. Refuse such predicate to your peril.
