I'm going to put this very simply.
Ancient people were all brown.
Different shades and hues. They didn't get separated by color. They got separated by geography, tribe, and nation.
Black people in the US are many different shades of brown. The only reason we say "black" today is in contrast to the racial construct of whiteness that whites invented. No offense intended. Just facts.
But everyone (including whites) came from Africa.
And yes, there are some black people who are confused and don't know these things and some of them think the darker you are the more black/African you are. This is not true.
One of the oldest tribes still in existence is the San Tribe of Africa.
If you look at their pictures you will see features of all races and cultures, from black to European, to Asian. They are a beautiful people and ALL we who have diverged from their genetic lineage, are beautiful people.
Many people forget where they came from and only see themselves as beautiful.
The theory I subscribe to as the origin of the white race does in fact involve a skin disease that mutated the melanin. Although the English word biblical translators used is "leprosy" that doesn't mean it is the same form of what we call leprosy today. My theory, based on certain sources, is that people who had this disease were thought to be "unclean" and people were afraid that it was something that could be communicated. So they camped to the north in these leper colonies. I don't know how we treated them. But perhaps we feared infection. The interesting thing about biblical leprosy was that it was considered clean, not when the person's skin went back to being brown, but when the person's skin fully changed to being all white. And at the same time you have people who born white or "albino".
Albinism is an inherited condition. So in theory, if there were camps of people with some sort of skin disease and it somehow affected their DNA, they could breed a type of albino that was fully white but, not having no pigmentation, but just a different type of pigmentation. If these camps getting bigger as more people were affected (or maybe even infected) then they would have to go further north. Perhaps, they eventually moved so far north and became so big, and went through so many rounds of breeding out the normal sort of albinism, that they eventually started to look better, retaining some of the African DNA, but really splintering off in a new direction and adopting the more modern European look.
And then out of that group, the blond recessive started coming out more and the blue eyes, green, especially under different environmental conditions. But all those features, including blond hair and blue eyes, are still African in origin. That's what's frustrating to me. The mainstream has taken a much more narrow (more inbred, sorry no offense) gene pool and said THAT is the image and standard of beauty and then equated the white skin (not light but white) as being good and pure when skin, like soil, there's no such thing. Darker soil has been thought to be more fertile; especially in comparison to sand. And yes, you don't want to be light skin in the desert because you're more likely to get skin cancer and die. And perhaps that's what led to darker tones being more dominant in Africa while lighter tones were able to escape the sun in colder climates. So when we talk about survival of the fittest... its not about superiority of a race but rather how much your body can adapt to its local climate. We would all die on the moon or under water just as quickly. I didn't know dark skin people can get sun burn too, but apparently they can. My godfather is an example.
But it's frustrating when whites who descended from black, try to act like they didn't. And that's why I say look at the San Tribe. The truth is we are virtually identical in terms of DNA, even errors in our DNA. That means we came from the same people. So why don't we see all see the beauty of color, just because whites want to have a very limited palette? Why glorify less color when you love flowers that are many? It seems to me like overcompensation. And then it's like most white women almost feel like they have to wear make up, adding color or risking sub burn to get a tan. This while many darker skinned people are more attracted to lighter skin people. Two Jamaicans live on my street and both are with white women.
At the end of the day color is something we should all love, appreciate, and find beauty in.
