Color of skin and race are two different things. There are races, for example, in New Guinea and sub-Saharan Africa that have essentially the same skin color but are as different genetically as two races can be. Skin colors in Japan overlap those in Europe to some degree, but those races have been evolving apart for tens of thousands of years. But don't kid yourself: Race is highly significant; racial "equality" is non-existent; and racial divergence is necessary for human evolution to continue.
