IIRC Blacks and Asians have some Denisovan genes. Whites have Neanderthal genes, so these questionable results do not apply to Honkeys.
Asians and Caucasians both have Neanderthal DNA-Blacks do not. Asians have Denisovan genes-so do Caucasians from Eurasia. There hasn’t been any Denisovan DNA found in Blacks-apparently, the people in Africa did not travel/trade much in prehistoric times. I seriously doubt that the inability to utilize Zinc can be blamed on the DNA of of our ancestors-more likely it is just a genetic quirk in individuals-like sensitivity to drugs, food allergies, etc. Individuals with depression respond very well to psychotherapy-and I don’t think it is a genetic condition in any case-it makes far more sense to believe it is situational, due to unpleasant life experiences, but that is just my opinion...
