Straight from Nick Wade in the journal of note the NYT – East Asians have thicker hair, smaller breasts and characteristically identified teeth that is different from other races.
Researchers tested this by inserting a known Asian gene mutation into mice and seeing if the mice developed different physical characteristics. The mice indeed grew thicker hair and had less breast tissue. Teeth are so different in mice that no conclusions could be drawn.
The method they used to test these changes can be applied to 400 other sites in the human genome. One might wonder what other traits they could test for… inclination to violence? intelligence? other personality traits? There is now a vast untapped trove of testable hypotheses for researchers to mine.
What’s also interesting is the age of this mutation. I didn’t have the impression that Asians as a group had already differentiated themselves from other races 35k years prior. I had for some reason thought that differentiation didn’t happen until much later, say 25k-20k years earlier. I thought that it was only in the past 10k years that much of what we see in today’s groups appeared and gave rise to our modern day stereotypes. If differentiation happened much earlier, any attempt to “homogenize” race (either by gov’t policy or by breeding between races) so that it really becomes meaningless has over 30k years of evolution to overcome instead of 10k. Egalitarianism is DOA.
