The "Out of Africa" Hypothesis, Human Genetic Diversity, and Comparative Economic Development

Quamrul Ashraf () and Oded Galor ()

No 2010-03, Center for Development Economics from Department of Economics, Williams College

Abstract: This research advances and empirically establishes the hypothesis that, in the course of the prehistoric exodus of Homo sapiens out of Africa, variation in migratory distance to various settlements across the globe affected genetic diversity and has had a persistent hump-shaped effect on comparative economic development, reflecting the trade-off between the beneficial and the detrimental effects of diversity on productivity. While the low diversity of Native American populations and the high diversity of African populations have been detrimental for the development of these regions, the intermediate levels of diversity associated with European and Asian populations have been conducive for development.
