The Major Divisions of the Human Race
Most anthropologists recognize 3 or 4 basic races of man in existence today. These races can be further subdivided into as many as 30 subgroups.
Ethnographic division into races from Meyers Konversationslexikon of 1885-90 is listing:
Caucasian races (Aryans, Hamites, Semites)
Mongolian races (northern Mongolian, Chinese and Indo-Chinese, Japanese and Korean, Tibetan, Malayan, Polynesian, Maori, Micronesian, Eskimo, American Indian),
Negroid races (African, Hottentots, Melanesians/Papua, “Negrito”, Australian Aborigine, Dravidians, Sinhalese)
