As I said earlier, when I was in school in the US (in the 1950s and 1960s), American Indians (Amerinds) were considered part of the Mongoloid race, since they were generally considered to have migrated to the Americas over the Siberian land bridge from Asia during the Ice Ages. However, I think even then that various anthropologists disagreed with that. Today, of course, anyone with the brains of a cockroach knows that the alleged divisions between the alleged races are entirely artificial..."Whites" and "Blacks" are as much different races as are collies and poodles.
