As one of the most complete archaic human fossils,the Harbin cranium provides critical evidence for studying the diversification of the Homo genus and the origin of Homo sapiens.However,the unsystematic recovery of th...
In eastern Asia,several Middle-Late Pleistocene human fossils,such as the Dali,Jinniushan,Hualongdong,and Harbin crania,evidently resemble each other and are phylogenetically closer to H.sapiens than to H.neanderthale...
