FYI They have the Silver Medals in select sizes as well . <| sep |> There are genetic differences that cluster around geographic ancestry . That is the stunning finding of that article . Of course , there are also genetic differences between blondes and brunettes . We say race is socially constructed not because of an absence of some genetic differences , but because we socially pick and choose which genetic differences to make important or unimportant , and fail to acknowledge that those differences are largely superficial skin color , hair texture , etc . . The overwhelming amount of human genetic code is the same regardless if you ' re from Asia , Africa or Europe . There is a long history of racists using science to prove their own biases of superiority in fact , Hitler used studies of this type made in the United States , and this is no different . Remember the old blue eye brown eye experiment ? I could argue those differences were based on genetics as well , but the social dimension of that distinction is still artificial .
