高加索人種
In 1873, the decade after the expulsion of Circassians from the Caucasus where only a minority of them live today, it was argued that "the Caucasian Race receives its name from the Caucasus, the abode of the Circassians who are said to be the handsomest and best-formed nation, not only of this race, but of the whole human family." Another anthropologist William Guthrie distinguished the Caucasian race and the "Circassians who are admired for their beauty" in particular by their oval form of their head, straight nose, thin lips, vertically-placed teeth, facial angle from 80 to 90 degrees that he calls the most developed one, and their regular features overall, which "causes them to be considered as the most handsome and agreeable".
