comment Were there prehistoric interaction between Caucasian and Asian people?
Maybe i should limit the scope to Eastern Asian. Before the Silk Road, are there interactions between eastern asian and European people? The geological closeness between the home ranges of Mongoloid and Caucasoid probably mean they must have lots of opportunities to interact. Are there many evidences?
