The concept of race classification in physical anthropology lost credibility around the 1960s and is now considered untenable. A 2019 statement by the American Association of Physical Anthropologists declares:Race does not provide an accurate representation of human biological variation. It was never accurate in the past, and it remains inaccurate when referencing contemporary human populations. Humans are not divided biologically into distinct continental types or racial genetic clusters. Instead, the Western concept of race must be understood as a classification system that emerged from, and in support of, European colonialism, oppression, and discrimination.Wagner et al. (2017) surveyed 3,286 American anthropologists' views on race and genetics, including both cultural and biological anthropologists. They found a consensus among them that biological races do not exist in humans, but that race does exist insofar as the social experiences of members of different races can have significant effects on health.
