The “Out of Africa” Hypothesis, Human Genetic Diversity, and Comparative Economic Development
研究提出并实证检验了史前人类走出非洲的迁徙距离影响遗传多样性，进而对各国经济发展产生倒U型效应，解释了非洲高多样性和美洲低多样性不利于发展，而欧亚中等多样性促进发展。
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.
