Other than white men, who has been in charge of this country for the past 400 years?
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)

Another popular division recognizes 4 major races
The world population can be divided into 4 major races, namely white/Caucasian, Mongoloid/Asian, Negroid/Black, and Australoid. This is based on a racial classification made by Carleton S. Coon in 1962. There is no universally accepted classification for “race”, however, and its use has been under fire over the last few decades.
