Assertion on Race...

 My assertion on race is that some people are of lighter skin complexion because they don't get as much Ultraviolet Radiation from the sun because of how it relects off of them. Depending on wheather you are closer to the sun or farther away and the amount of body hair you have because that is what reflects the radiation off of you. People of a lighter complexion usually have more body hair than people with a darker coplexion.
