1 - From some of the studies I have seen before, ancient Egypt(ANCIENT, from the beginning, not Ptolemaic-Greek or Roman Egyptians that Cacs try to pass as eras close to the beginning of Egypt) was originally a place consisting of Nilo-Saharan, Nilotic and Cushytic(These Cushytic were already a mix of ancient Nilotic with ancient Levantine) speaking people. These people eventually mixed for many generations, creating a new group of their own. These were the founders of ancient Egypt that were later invaded by a range of different groups. The change didn't start with Arab invasions. It started way back.
1.1
But all this situation is funny because Cacs used to say that the true ancient Egyptians were Copts and spoke a coptic language. However, Copts are a recent group, developed after the introduction of Christianity into Egypt. I mean, Nabta Playa dates to 7500 BC, showing affinity to Nilo-Saharan speakers but heavily admixed Copts(ethnoreligious group born out of 1st Century AD Christianity) are the ancient Egyptians?
2 - Also, some more context is needed:
2.1 Berbers were not really related to ancient Egyptians. And today, they are mostly mulattoes ruled by Arabs and Turkish descendants. Some Jewish descent rulers too, because some Jews that were expelled from Iberia ended up in the Maghreb. Anyways, true berbers are not close to white. They are mostly brown like Tuaregs PS: Funny, even Gaddafi(described by many as a true Berber) was an Arab descendant. He was a Qadhadhfa, an Ashraf Arab tribe, related to Bedouin nomads from Arabia.
2.2
Originally, Berbers came to exist from a mix of ancient native black Saharans(that lived in the region during the Green Sahara period), ancient Levantines and also ancient Southern Europeans. Plus, they have constantly received Middle Eastern DNA through multiple conquests. From Phoenicians to Ottoman Turks and even modern Arab rule in places like Morocco. PS:To this day, in places like Morocco they are still ruled by an Arab dynasty, called the Alawi/Alaouite dynasty, that immigrated from Saudi Arabia to Morocco and has been ruling them since the 17th century.
So, the idea of grouping "Ancient North Africa" into one and also projecting it to modern populations in North Africa is just Cac nonsense.
I seriously don't care much about North Africa or even Egypt, since the northern part of Africa is one of the most conquered regions in history but yeah, I don't think the video is entirely correct.
PS: The picture above gives you a good perspective of the multiple changes that happened in the North, specifically Egypt. And it is missing some. For instance, it doesn't even include the Nubian rule or the fact that most rulers from 1952 - Present haven't been really Egyptians. They have been mostly Arab descendants, with some Albanian elites still controlling important sectors. I think the only somewhat native ruler since 1952 was Anwar el-Sadat. Modern Egypt is an Albanian project.
Also, I seriously wonder how Cacs will spin most of their traditional lies about history. Archaeology is starting to receive a lot of funding and attention. And right now, they are too deep into their lies. Also, I think that archaeology will end up proving that African oral history has been more reliable and consistent than "I'm white and I say so" writings.
