The Roots of Global Inequality: The Role of Biogeography and Genetic Diversity
检验了贾雷德·戴蒙德的假说，即前现代时期全球技术差异源于生物地理因素，同时考察了遗传多样性作为不平等根源的替代假说，发现后者缺乏稳健证据。
This paper adds further evidence supporting Jared Diamond’s hypothesis that global technological differences in the pre-modern era were fundamentally due to bio-geographic factors: the time elapsed since the onset of agriculture and husbandry, the size of the population relative to the territories, the shape of continents. An alternative hypothesis, that genetic diversity within populations is the ultimate cause of global inequalities, is also examined. Results show how there is no robust evidence supporting a possible effect of genetic diversity on international differences in population density and technology in the pre-modern era.
