What are the three racial groups in the world?

The concept of racial groups is often simplified into three broad categories: Caucasoid (or European), Mongoloid (or Asian), and Negroid (or African). However, it's important to note that these categories are based on outdated and overly simplistic racial classifications. Modern understanding of genetics and anthropology emphasizes that human genetic diversity cannot be neatly divided into these groups, as there is more variation within these categories than between them. Racial classifications are increasingly recognized as social constructs rather than strictly biological ones.
