GGG Ping.
What does GGG stand for? My first thought would be Gravytrain Grant Grubber.
Undoubtedly this study was skewed by the fact that mostly Europeans remains have been studied IE: the Cro-Magnon people of Northern Europe who have still today, larger faces than Asians or other peoples. How many Asians are in the fossil remains? Another point to consider suppose the genetic factors where split 50-50, farming allowed more smaller faced people to survive and past on their genes this would be perhaps be survival of the unfitest.The same arguments could be made about eyesight and an extremely slim build, my slim near sighted brother inlaw would have died in the first famine of childhood if he hadn't fallen off a cliff or been eaten by a lion earlier!
