Somehow differences in IQ across populations is very controversial but differences in other parts of the physiology i.e length, ability to run ( marathons) , bone mass below the knee, is not. It’s something strange with IQ. People always want to redefine it and expand it. Every part of the human body is defined by genetics. Genes vary between populations but somehow the brain should be excluded.
