Caucasian variety — «I have taken the name of this variety from Mount Caucasus, both because its neighborhood, and especially its southern slope, produces the most beautiful race of men, I mean the Georgian; because all physiological reasons converge to this, that in that region, if anywhere, it seems we ought with the greatest probability to place the autochthones (birth place) of mankind» — Blumenbach J. F. De generis humani varietate nativa.— 3rd ed., 1795, trans. Bendyshe (1865).
