Abstract:
This research establishes that migratory distance from the cradle of anatomically modern humans in East Africa and its effect on the distribution of genetic diversity across countries has a hump-shaped effect on nighttime light intensity per capita as observed by satellites, reflecting the trade-off between the beneficial and the detrimental effects of diversity on productivity. The finding lends further credence to the hypothesis that a significant portion of the variation in the standard of living across the globe can be attributed to factors that were determined in the distant past.
