If the earliest African-Americans were black, why weren't people in North Africa and the Middle East black?

The first Afro-Asian people probably lived about 15000 years ago, and they were probably black (no one can say for sure how black they were, but I personally estimate that they were near the southernmost tip of the Arabian Peninsula in Kotri, as shown in the following figure), instead of the common sense of "race" or the black close relatives gene of blacks in West Africa, Central Africa, South Africa and East Africa.

Considering geography, archaeological genetics and archaeology, I think the most likely explanation is that the origin of primitive Asian-African languages is related to the population spread in Northeast Africa, which is distributed between West Asia and Africa. The birthplace of E-M78 haplogroup may be near Egypt or Sudan.

In addition, the Taforalt DNA sample belongs to E-M78 from Morocco (15 kya), which has a very special autosomal additivity (recently, it is estimated that the good genetic evidence is probably ~ Africans whose ancestors came from West Asia in the late Paleolithic period +55% ~ 45% African ancestry before the ancestors of modern sub-Saharan Africans appeared, but they are closer to Africa than other sub-Saharan Africans). We don't know what they look like, but they must have dark skin.

The autosomal mixed genes of "Taforalt-like" or "Ibero-Mauritian-like" happened to account for a significant minority (about 27%) in the genetic composition of Mrs. Natu in the Middle Stone Age, and Mrs. Natu was the main ancestor of the final Levant and Arabs. Most of them (about 73%) came from local West Asians, but in a proper socio-economic and cultural environment, these inputs were enough to lead the region to turn to Asian-African languages. Similarly, ancestors related to Mrs NATO or Ibero-romulus can also find important ethnic minorities in the Afro-Asian language region of East Africa, not to mention the genetic ancestors of North Africa.

Then, its ultimate origin must be somewhere in North Africa, although the genetic composition of people there must be different in the late Paleolithic period. Today, Saharans and Maghreb Berbers have more "Taforalt-like" genes, but still no more than 30%.

15000 years ago, many people in the world, including a large number of people in Europe and West Asia, still lacked specific combinations of different genes, and finally created fair skin. The cumulative effect comes from many different and lighter skin colors, from dark brown to very light brown (such as "white").

Therefore, it is not surprising that the first primitive Asian Africans were probably dark skinned. Some major skin mutations changed color more than15,000 years ago (the allele related to SLC24A5 was 29,000 years ago), but they were not found to create a real light-skinned person with very high frequency, except in some areas of Eurasia.
