When human DNA is examined however they see no clear lines. If you traveled slowly from, say, Nigeria to Egypt to Turkey to Germany, the DNA of people along that path changes little by little the whole way. There's no spot where you can say "okay, HERE is where one race stops and the next one starts." It's all one long gradual blend, not separate chunks.
Even then, people in the same "race" can be more different from each other than people in different "races." Two people who'd both get called "White" could actually have more genetic differences between them than one of them has compared to someone called "Asian." That breaks the whole idea of race being a tight genetic package.
Specific big boxes labeled "race" don't match how genes are actually organized. It's more like humanity is one long, blended spectrum, and race is a label people put on top of it — not something built into the DNA itself.
Lets discuss something real instead.
Derrick Bell is a great place to restart the thread.
