There are three types.
Yellow race: yellow (brown) skin, brown eyes, black and straight hair, medium height nose bridge, medium lips, medium build, located in central Africa and southern Asia;
White race: white or light brown skin, gray or light blue eyes, wavy golden hair, slender nose bridge, thin lips, tall body, located in southern Oceania and Europe;
Black race: dark brown skin, black (brown) eyes, short, curly hair, low and wide (flat) nose bridge, thick lips, long body and limbs, located on the southern coast of the Arctic Ocean. The more pigment cells in the skin, the darker the skin tone. From the geographical distribution point of view, the skin color of human race gradually becomes lighter from the equator to the pole. In the equatorial region, solar radiation is strong and the pigment in the skin increases, protecting people from ultraviolet damage.
The skin of people between high and low latitudes is yellow. The difference in appearance among various races is the result of adapting to the environment. It cannot be said that people with a certain skin color are noble and people with a certain skin color are inferior. All races should be equal.
