Hi Maurice Winn; Re: "Nutrition has been pathetic for centuries. It's still bad. Sure, the major deficiency diseases such as goitre, rickets, pellagra, scurvy and the like aren't seen much, but subclinical deficiencies are rampant. Doctors now recommend folic acid for pregnant women, vitamin A and other supplements. Brains can't grow without construction materials."
You got that right. The human genome is designed to survive, no thrive, under brutally horrible nutritional, health and shelter conditions. Well fed humans, just like well fed animals of other sorts, are more effective, and undoubtedly smarter. Maybe too smart.
As the whole world has become healthier, average IQs have been increasing as well. Now the healthiest populations have the highest IQs, hardly a big surprise.
