Human nomenclature: from race to racism

Throughout time, evolutionary biologists have attempted to classify human beings according to a nomenclature based on supposed patterns of biological differences that have been used to suggest hierarchical categories. Recent genetic evidence disproves the assumption that races are genetically distinct human populations. Several studies refute human categorization as a severely flawed yardstick. For many, race is a construct that must be overcome in order to eradicate racism. Personal experiences of racism, harassment and discrimination are associated with multiple indicators of poorer physical and mental health status. Additionally, socio-economic differentials are likely to be a fundamental explanation for the observed inequalities in health status among minority groups. This commentary examines the discrepancies that race, ethnicity and similar human nomenclatures present. Furthermore, the potentially harmful consequences of the "scientific" use of race, in the form of stereotyping and racism, are discussed.
