The Long Shadow of Genetic Capital

摘要

Comparative analyses of human genomes have contributed to a spatiotemporal narrative that begins in East Africa and extends to the other continents. These historical traces reveal a decrease in genetic diversity as migratory distance from Addis Ababa increases. Ashraf and Galor present the hypothesis that genetic diversity has exerted a long-lasting effect on economic development-which is quantified as population density in the precolonial era and as per-capita income for contemporary nations-beyond the influences of geography, institutions, and culture.
