Step 1: Understanding Human Racial Classifications.
Human races have been traditionally classified into several categories based on physical and geographical characteristics. These classifications have evolved over time, but traditionally, the main categories are:
- Caucasoid: Refers to people with lighter skin and European, Middle Eastern, and South Asian ancestries.
- Australoid: Refers to indigenous peoples from Australia and the Pacific Islands, often characterized by distinct features like dark skin and curly hair.
- Negroid: A term used to describe populations of Sub-Saharan African descent, characterized by darker skin and other physical traits.
- Mongoloid: Refers to populations of East Asia, Southeast Asia, and the Americas, characterized by distinct facial features, including epicanthic folds.
Step 2: Conclusion.
The major human racial categories based on physical characteristics are Caucasoid, Australoid, and Mongoloid. Negroid, although historically used, is considered outdated and not in common use today.
