Brains are all the same color. And skin color is a product of ancestry. The darker the skin the better the survival rate around the equator. White people would have died out under those conditions. People with more melanin in their skin could survive anywhere.
Don’t be f***ing stupid. You ever hear of things like shade, buildings, clothes? White people have been living in Brazil and Columbia for 500 years. I know Egypt’s not on the equator but it’s still friggin hot there. White people ruled Egypt for 500 years with the Greeks and Romans. And Australia’s pretty close to the equator also.
