There exists a company that can take your DNA and assemble a Map showing where your ancestors lived and came from. OTH, we may not be able to "prove" race from DNA, blood work, etc etc. but one thing for sure; when I see a man or woman of Chinese descent, I know what I see. When I see a Black man, I don't need to run a blood test to know what I am looking at. Ditto for whitey and all the other racial groups. Unfortunately for the Marxists, we are NOT all equal and the same.
