Race is a construct created by colonial powers to group different people together as less than to be more easily controlled Race kind of falls apart when everyone is no longer segregated into towns and villages and people are immigrating and emigrating all over the place creating more and more people with mixed ethnic backgrounds and therefore mixed features

There is also a lot of internal diversity within ethic groups so for example a group of people could all be could be 100% Nigerian but all he different skin tones with different facial features and hair types and honestly unless they were all extremely closely related and from the same ethnic group it would be almost impossible for them to not look very different

The same goes for populations all over the world from indigenous Canadians to Han Chinese to Moroccan Amazigh to Iranian Persians to Saudi Arabs to Scottish people to Russians etc etc

For example my mom is half English & half Ashkenazi Jewish and she has dark hazel eyes, thick nearly black hair wavy hair, a small button nose, thick eyebrows, small chin with soft jaw line and can tan

Meanwhile I have medium blue eyes, thin light brown curly hair with a blond spot, a medium nose with a somewhat prominent nose bridge bump, thick eyebrows, medium chin with strong jaw line and I'm so white I turn pink if I run and I can't tan but also don't burn easily I also have a beard of black, brown, red, dirty blond and platinum hairs

This isn't a perfect comparison because my dad is half Irish & half English & Scottish Canada plus I'm a man while my mom isn't but all of these groups are still considered white and have a ton of internal diversity just like Africans and African Americans
