It’s easier for us to admit differences in physical abilities than intelligence. Rather than thinking in terms of race we should think in terms of region. We know there isn’t a black gene for physical abilities the anaerobic abilities comes from a very specific region in Africa just as the aerobic abilities do. <br><br>An interesting an idea I had regarding intellectual ability could be that the group of people that left Africa might have been more endowed with intelligence and that’s why that group or leaders that lead that group left. <br><br>I understand though because it needs to be taken in by the way society at large will take in the information. People usually want something boiled down so it could create a false narrative about race and iq because it’s very complicated.,(reply>), Intelligence IS a  physical difference.
