After I have been to Taman Negara, and seen the Australian outback Aborigines, I could make an assumption that natives come from the root of African origin. Because these aborigines shared similar traits: curly black hair, high melanin skins, live in the open wild nomadic life, hardy, highly adaptable to changing environment, and simple and shy in nature.
This is an interesting observation because they are among the first explorers across the globe, way before Columbus discovered new land in America, nor Marco Polo traveling to the East.
Maybe any of you could provide some observations to add to my simplistic theory of natives from African?
