Maybe you have heard that the Celts — Scots, Irish and Welsh — were all no more than five feet tall in their native estate. Now, it’s commonplace to see very tall and large Celtic-descended people, because they have prospered here with good nutrition since the mid-1800s, and some a century before that. Slave-descendents of African origin, on the other hand, did not achieve full civil rights until about 60 years ago. I see no reason why members of their group cannot also begin to increase in health and intelligence if they can change behaviors to achieve middle-class habits and nutrition.

I wish them luck. Why wouldn’t every race have increasing IQs over time?
Small stature Asians, for instance?
