Just for clarification — most Europeans have mixed ancestry considering all of “hordes from the east” that plagued the Roman Empire — so if you go way back there is not a homogeneous Europe.
Having spent time in Asia I know that most coastal peoples look Chinese but in the villages there is a more aboriginal look.
You are certainly right about that. Most of us are also descended from slaves, too. 25% of the population of the Roman empire were slaves. Do you want to get hung up on that or celebrate freedom today?
