The question “why do black people have big lips” is based on a racial stereotype that lacks scientific basis. Lip size is determined by genetics and varies widely among individuals of all races.
The diversity of lip size within the black community is as vast as in any other population group. Some black people have thin lips, while others have full lips. The shape and size of one’s lips are influenced by a combination of genetic and environmental factors, including climate, diet, and personal habits.
