Is race skin deep

Answer 1

No. What people perceive as racial groups are combinations of physical characteristics, not simply skin color. Also, to some degree, race is a social construct which involves culture and ethnicity as much as it does physical attributes. However, racial groupings do correlate well enough with biomedical disparities between different population groups, particularly probabilities of different medical conditions, to be helpful in diagnosis. Genetically, it is possible to identify clusters of multiple genetic markers that correlate fairly closely with racial phenotypes, but no single genetic marker is exclusive to any one cluster. Certainly, the early twentieth-century theory that different races represent genetically divergent populations has been completely disproved by modern genetic studies. In terms of taxonomy, race is meaningless; all humans are of the same subspecies.
