Modern Egyptians have some admixture from West Asian invaders, Hyskos, Greeks, Persians, Arabs, Berbers, Levantines, Mamluks etc. So they will look lighter and more Caucasoid than the Ancient Egyptians. There is also some Black admixture; they were after all conquered by the Nubians, and later Islam brought slavery, but looking at some of the pre-Nubian statues, there already were some Blacks in Ancient Egypt in high positions.
The best representation of Ancient Egyptians is from the mural in the Tomb of Seti. In Gates’ book, The Races of Man, the Ancient Egyptians portray themselves as brownish, while the Semites and Berbers are portrayed as White and the Nubians as Black.
Ancient Egyptians in my humble opinion are their own distinct group.
How will modern Egyptians look more Caucasoid than the Dynastic Egyptians? The Dynastics were 13% Black, and the modern Egyptians are 30% Black, 20% in the north and 40% in the south. The Black percentage of the stock has increased by 2.5X, and the Caucasoid percentage of the stock has decreased by 20%. Given that, how could they possibly look more Caucasoid?
The problem here is that we look at these ancient races through modern lenses. Caucasoids in some parts of the world looked quite different than they do now.
And this is true not only of Caucasoids but of other races too. Racial stocks existed then which have vanished from the Earth. Kennewick Man’s race has vanished. There is not a trace of his race left. There are only a few minor races that look somewhat like Kennewick in the sense that they place closest to him on a graph, but they are not his people. His people are gone.
The ancient Romans are gone. There is nothing left of them at all. It is another vanished race. Sure, the modern Italians have evolved from them, but few if any modern Italians are actually “Romans” because this racial stock has vanished.
It is clearly the same with the ancient Egyptians with the caveat that skull studies show broad continuity between modern and ancient Egyptians. Modern Egyptians look more like Dynastics than any other stock on the planet does, but in general, they are not Dynastics.
The Dynastics were a peculiar Caucasoid race that has vanished from the Earth. However, based on studies of skulls and even genes, the Dynastics were absolutely Caucasian. The skulls plot clearly Caucasian on a graph. And 87% of the genes are derived from the surrounding region, mostly from the ancient Levant where the pre-Dynastics originated prior to 13,000 YBP. At that time, these archaic Levant Caucasians moved out of the Levant, down into Egypt and over time evolved into the Dynastics.
