The history of Rapes are true as some of you have said, but there's also another aspect to this. I was watching something on the History Channel and it was on the origins of the Amazon and the Hmong people came up. Some Hmong people are descendants from the Mongolian/Tibet Plains and that's why some Hmong people have the light hair/ light eye genes in their genome. Some Mongolian clans have light hair/light eye and Asian people from that region or have ancestors have that gene.
Back to the Amazons, some historians and anthropologists believe that the Amazons from the Roman/Greek days hailed from the Mongolians because after doing many research and carbon dating on the bones between the two places, they share similar traits.
