i dont get it. if science says that we are all descendants of mitochondrial eve (except some african tribe), y-chromosome adam and if africa has maintained its genetic diversity as our first home to exist. and if europians are people of low genetic diversity (essentially "one" group), then why are people racist towards africans and not europeans? arent africans supposed to be genetically superior and more diverse than europians? why do people keep ignoring this? is there any scientific response to such people?
