Which term describes the biological and anatomical features that distinguish groups of people?

The term that accurately describes the biological and anatomical features distinguishing groups of people is race. This concept typically encompasses perceived physical differences, such as skin color, facial features, and other hereditary traits. While race can have social and cultural implications, it fundamentally derives from biological characteristics that are often used to categorize individuals into distinct groups.

In contrast, culture refers to shared beliefs, customs, and behaviors of a group, which encompass language, traditions, and practices, and does not directly relate to biological differences. Ethnicity, while closely related to race, refers more specifically to a group’s shared cultural heritage and identity based on common ancestry, language, or cultural practices, rather than on biological features. Nationality pertains to an individual's membership in a nation, often based on citizenship, and does not address characteristics that are biological or anatomical in nature.
