The sub species of man
Experts within the research community say a small but stubborn streak of racial profiling has long persisted in the medical literature, borne out in studies that attribute health disparities between blacks and whites not to socioeconomics or access to health care alone but also to genetic differences between the races—a concept that implies that a biological category of race exists.
And just one more differencebetween some sub species of Homo sapiens is the ability to digest milk when adult.
Many in the scientific community know all this but are too frightened to come out of the closet.
