What do you call someone who doesn't understand genes create biochemicals which create physiology ?
Look at the end of the day we are biochemical robots, ignoring gene differences is good for no one.
African populations have higher prevalence of sickle cell, Europeans have higher prevalence of Alzheimer's. both are thought to be have evolved for some reason.
Genes are not magic. They are very complex code. The idea genes exist for no purpose died with the advent of metagenomics. If there are any gene differences, they have likely behaviorial implications.
