== uncited additions == 

  
 dear editors, 

 Arguments advancing the notion of racial similarities between a Nubian and a Dravidian, both classified as Negroid, Afrocentrists contend, are far more credible than those of beween, say, a Swede and a modern-day Turk, both classified as Caucasian. Traditional racial classifications, after all, are not based on genetics, but on phenotype 

 this is an uncited addition and seems like it may be "original research".   I won't remove it, the editor that added it may have just forgotten to put a reference and it seems fairly believable, but there is a lot like this in the article and it is eventually going to be removed for lack of verifiability.   your time would be better spent adding citations or cited material than adding even *more* uncited material. 

 please make sure you've read the following:
