Sexual behavior is the crucial element of global migration and the population expansion of humans in the past Based on the previous proposal that female pubic length is inversely correlated with the sexual activity of her male partner, the sexual activity of hominids in Palaeolithic Europe, Middle East and East Asia was assessed. A long pubic feature in the female pelvis of current East Asians can be seen in the Asian Palaeolithic hominid, i.e. the Jinniushan (around 200,000 years old), China. On the other hand, short pubises, characteristic of current Europeans, were seen in Pleistocene female hominins (except for Neanderthals) unearthed in Europe and Middle East. It was inferred from the previous proposal that their male partners could be sexually more active than East Asian male hominins. In addition to East Asian characteristic facial and dental morphology, close similarity in the sexual behavior of current East Asians to the Jinniushan can be satisfactorily explained by the model of the regional origin of the East Asian population.
