Ever since our early human ancestors left the homeland in Africa, their descendants migrated, radiated and occupied all major ecological niches around the world and then developed their own Paleolithic cultures. The ancient mongoloid in East Asia could have been the largest subspecies in terms of the dispersal rate and scale ever since the last glacial. The main purpose of this paper is to review the current researches on the origins and then on the status of southern mongoloid by physical anthropologists and molecular biologists. Two key questions are discussed in this paper: first, the major morphological characteristics of southern mongoloid that can be used to distinguish northern mongoloid in East Asia? Since when they were separated?
