The stupid nonsense that is anthropolgy:

"The concept of a Caucasian race or Varietas Caucasia was developed around 1800 by Johann Friedrich Blumenbach, a German scientist and classical anthropologist.[3] Blumenbach named it after the Caucasian peoples (from the Southern Caucasus region), whom he considered to be the archetype for the grouping.[4] He based his classification of the Caucasian race primarily on craniology.[5] Blumenbach wrote:

"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; and 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.[6]"
