This research presents the first evidence that moderate fecundity maximized long-run reproductive success within the human species. Exploiting an extensive genealogy record for nearly half a million individuals in Quebec during the seventeenth and eighteenth centuries, the study traces the...

This research explores the biocultural origins of human capital formation. It presents the first evidence that moderate fecundity and thus predisposition towards investment in child quality was conducive for long-run reproductive success within the human species. Using an extensive genealogical...

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...
