🧑‍🤝‍🧑 Historical Racial Classifications

Historical term: “Caucasoid”

Obsolete classification used in older textbooks for peoples of Europe, West Asia and North Africa; not a valid biological race.

Historical term: “Mongoloid”

Obsolete classification used in older texts for East/Central Asian and some Indigenous American peoples; not a valid biological race.

Historical term: “Negroid”

Obsolete classification used in older texts for sub-Saharan African peoples; not a valid biological race. Do not extend this label to Oceania.

⚡ Quick Recall
Human variation is continuous and overlapping. Learn these labels only as obsolete historical classifications; modern anthropology does not divide humanity into three discrete biological races.
