The term "Caucasians" generally refers to people of European descent, although it can also include individuals from parts of the Middle East and North Africa. This classification is based on historical and anthropological studies that categorize humans into different racial groups. The term originates from the Caucasus Mountains, which were once thought to be the origin of the white race. Caucasians typically have lighter skin tones, but there is a wide range of physical features within this group. They may have various hair colors, eye colors, and facial structures. The concept of race is complex and often debated, as it encompasses cultural, social, and genetic factors beyond mere physical appearance.
