For those who down voted me because I hurt your feelings lol :)

Here is a study about racial differences. Hell.. I even learned this in high school.

===================================

Here is what this article says.

"The popular classifications of race are based chiefly on skin color, with other relevant features including height, eyes, and hair. Though these physical differences may appear, on a superficial level, to be very dramatic, they are determined by only a minute portion of the genome: we as a species have been estimated to share 99.9% of our DNA with each other.
