I mean, is the biological concept “race” a scientifically meaningful way of explaining human variation?
Correct me if I am mistaken, but arguably there is no one group of humans that is completely distinct according to any bodily characteristic or group of characteristics (hair, skin, etc), blood type, or DNA. There is just as much genetic difference between two people of the same ethnic population as there is between any two humans on earth at random. If that’s true, it means that what distinction does exist is simply due to the fact that we are individuals instead of members of a biologically distict race.
Many anthropological organizations have officially stated their rejection of “race” as a way of understanding human diversity. Instead of distinct races, some have suggested that humanity is more of a continuum with gradual changes.
Sorry I had to be somewhat vague given my limited resources at the moment, feel free to use your favorite four-letter word if you need a statement to be supported. Oh, and keep in mind that cultrually based “ethnicity” does exist, as do racial perceptions–these should not be confused with the issue at hand.
