The term "different races" refers to groups of people who are distinguished from one another by physical characteristics such as skin color, hair texture, and facial features. These differences have been used historically to categorize human beings into distinct categories or groups based on their ancestry and heritage. The concept of race is a social construct that has evolved over time and varies across different cultures and societies. While some people believe in the biological reality of race, most scientists today agree that there is no genetic basis for racial classification. Despite this, the idea of "different races" continues to be used as a way to understand and explain differences between groups of people around the world.
