" Q: But isn’t race “just skin deep”? Don’t most scientists now agree that race is a social construct, not a biological reality? A: Biological evidence shows that race is not a social construct. Coroners in crime labs can identify race from a skeleton or even just the skull. They can identify race from blood, hair, or semen as well. To deny the existence of race is unscientific and unrealistic. Race is much more than “just skin deep. "
