In 1900, Joseph Deniker said, the "Mongol race admits two varieties or subraces: Tunguse or Northern Mongolian... and Southern Mongolian".
In the 1944 edition of Rand McNally's World Atlas, the three subraces of the Mongolian race are depicted as being the Mongolian race proper, the Malayan race, and the American Indian race.
Archaeologist Peter Bellwood claims that the vast majority of people in Southeast Asia, the region he calls the "clinal Mongoloid-Australoid zone", are Southern Mongoloids but have a high degree of Australoid admixture.
Professor of anthropology, Akazawa Takeru (Japanese:赤沢威) at the International Research Center for Japanese Studies, Kyoto, said that there are Neo-Mongoloids and Paleo-Mongoloids. Akazawa said Neo-Mongoloids have "extreme Mongoloid, cold-adapted features" and they include the Chinese, Buryats, Eskimo and Chukchi. In contrast, Akazawa said Paleo-Mongoloids are less Mongoloid and less cold-adapted. He said Burmese, Filipinos, Polynesians, Jōmon and the indigenous peoples of the Americas were Paleo-Mongoloid.
