Race and Genes

I learned about how race is more of a societal concept than actual fact today. It's fascinating that race has absolutely no genetic basis. There is no single absolute way to distinguish one race from another. We are all incredibly scientifically similar. I read one fun fact that says that fruit flies have more genetic variation than humans. On top of that, looking at the genetic variation that does exist between people, about 85% of it is between individuals in local populations. Any given two people in one population are likely about as genetically diverse as two people in two different populations. Most variation in the genetics of people are caused by mutation.
