Could it be that racism had occurred since the dawn of human existence? According to Business Insider’s “DNA Of Ancient Human Spawns New Theory Of Why Europeans Became White” article by Dina Spector, ancient humans from specific parts of the world began to lose dark skin pigments for they had switched to a diet which contained more grains, thus they (researchers) assumed losing dark skin pigments helped ancient humans to synthesize vitamin D from the sun more readily. I don’t think this is right!
Personally, I myself know nothing about this field of science, and I don’t have any awesome knowledge in related areas. Nonetheless, I have opinion in regarding to this study. For me, I like to borrow Darwinism’s bits and pieces, thus I like to think that in the ancient time the natural selection had created few skin anomalies (e.g., white skin, yellow skin, red skin, brown skin) in ancient human population. These ancient skin anomalies had allowed the ancient humans to become racist and stick to similar skin groups.
As time progressed, ancient people with same skin color began to populate more and more, thus they had weened out the ancient people who shared the minority skin colors in a specific ancient human group. Moreover, different skin color groups (e.g., white skin, black skin, yellow skin, red skin, brown skin) traveled farther apart from each other, and so they developed earliest unique customs, living conditions, traditions, and so on. I surmise much later on they began to meet up again, and thus we had the so called “the clashes of ancient civilizations” of people who did not share same skin colors. Obviously, these cases were true only when such occurrences had occurred for the very first time for each unique “clash of ancient civilizations” which could depict the clashed of different skin color groups (i.e., clans).
In conclusion, I don’t think we can know for sure what had happened which allowed the ancient humans to develop different skin colors. Obviously as time progresses and the advancing of technologies, we might come up with an even better answer than what we have had in regarding to this specific quest. My assumption on the development of skin colors of ancient people might be off the mark by a gazillion miles, but this is my own opinion and explanation to why ancient people began to develop different skin colors. I can’t agree with the article which I had mentioned in the very first paragraph. If I understand this article correctly, it assumes that ancient humans could morph to white skin and shed their dark skin pigments at will.
