Don't get me wrong, I'm not saying there are no differences between ethnicities, just that those differences are based on ancestry not race. People of a specific "race" don't share the same ancestry all the time, some times they have more in common with a different "race" than their own. Race as we know it today is a means of classifying humans that came about at a time when colonial expansion was booming. Classifying people based on their outward appearance was all too convenient. It's like someone learning how to code who found out there are thousands of programming languages and categorized them using terms like "curly brace language","lots of parenthesis language","indentation oriented language". It's lazy and childish. But once you learn more about the languages you should abandon the old ways of classifying things.
