text: Yes, it's true.  Developing dark skin was nature's way of providing more protection from the sun's rays. That's why people tan, it's to help protect the skin. Light skin burns easily. Light eyes are more sensitive to bright light. Have you also noticed that  most black americans are not real dark like true africans? They aren't exposed to that harsh sun anymore and have lightened up. I'm not sure about the hair "curling up from steam" it sounds reasonable, but actually, straight hair when seen under a microscope is round like a pencil, and tight curly hair is flatter like a ruler. Soft curly hair is oval shaped. It's the follicles that determine curly or straight. But hey, it might have originated that way from heat, I don't know.\nps. I think brown skin and green eyes are gorgeous, and also shiny black hair with ice blue eyes too. It's different.
