They dont really do that. Most genetic studies acknowledge there is more nigger blood in Egypt than there was in the past. Genetic studies show ancient Egyptians were genetically closest to Levant people. Also, even historically, NATIVE egyptians were never anything special. They managed to build a significant empire because they were basically living on easy mode living on the nile with very fertile land. For 1000s of years, and even Egyptians will acknowledge this, Egyptianshave been ruled by foreigners, be it Greeks, Persians, Turks, and even now, the upper class in Egypt is Albanian, and even the former ROYAL FAMILY of egypt, which still has living members mind you, has FRENCH blood.
Egypt's main issue, I'd argue, is not genetic, but geographical. The country has 100 MILLION fucking people yet they're all clustered around the nile with NO hope of expanding outward into the wasteland around them.
Nah, Egyptians have played a massive role even now, in medevil and modern times, many Egyptians have invented and discovered alot of scientific advancments.
That's def a factor, but like I said, it's mostly geographic
