Wrong again, US boy. ‘Caucasian’ actually included most of Asia, since ‘Mongoloid’ only properly described East-Asians like the Chinese, Mongols, Siberian natives etc. Indians and Arabs (i.e.Aryans) were included in ‘Caucasians’, although the definition was debated.

Also, the ‘scientific racism’ theory was thought up at the University of Göttingen in Germany, when the US was just a few years old.
