The notion and definition of races have changed over time. With the nineteenth century being the period when the formal classification emerged and three "great races" were recognized under the technical terms of Negroid, Caucasoid and Mongolian.
Black race or before officially does he Negroid race is a historical racial category. It was one of the three main historical races, alongside the Caucasoid and the Mongoloid races. The major population included in the category in the 19th century and early 20th century were blacks from sub-Saharan Africa. As with other races, the black race is divided into subtypes.
In the past, Australian Aborigines, Melanesians and Negrito as well as Papuans (the inhabitants of New Guinea) were included in the Negroid race but have now since the 1940s generally been referred to as the Australoid race. Carleton Stevens Coon, the American physical anthropologist rejected the notion of a unified Negroid race in his 1962 book ” The origin of races '', dividing the population of black Africa into a Congoid race (Central and West Africa) and a Capoid breed (South and East Africa).
More recently, the term Africoid has been used to integrate into the black race more different types of dark-skinned people, including the peoples of East Africa, the Horn of Africa (Ethiopians, Eritreans, Somalis and Nubians)
The term Caucasian race (or Caucasoid, sometimes also Europid, or Europoid) refers to the race or phenotypes of all or part of the indigenous human populations of Europe, North Africa, the Horn of Africa, West Asia, Central Asia and South Asia.
Commonly used in American English, the term "Caucasian" (rarely supplemented by the word "race") is sometimes reserved for Europeans and other lighter-skinned populations in these areas, and can be considered equivalent to the various definitions of white people. The term continues to be used widely in many scientific and general contexts, generally with a narrow meaning of "white", specifically American white in the context of the United States.
The United States National Library of Medicine has used the term "Caucasian" as a race in the past, but ceased its use in favor of the term "European", thus avoiding the now suspicious term "race".
More recently, the inhabitants of the Horn of Africa have started to be included in the larger Africoid group as another type of blacks instead of being an extension of the Caucasian group resulting from the mixing of blacks and Arabs.
The term " Mongoloid " (or Oriental, also Mongolian) is a historical racial category used to describe people from East Asia and Southeast Asia. Its use comes from a variation of the word "Mongolian," a people of East Asia who were considered one of its major proto-populations.
The Mongolian race is generally considered to contain two subtypes: Tunguse or Northern Mongol… and Southern Mongol ”. The inhabitants of East Asia are called Northern Mongoloids as opposed to the peoples of South Asia or Southeast Asia which are the Southern Mongoloids.
Nowadays, terms such as Asia, East Asia, South East Asia which are more neutral seem more appropriate to describe the different groups of people living in Asia and who share certain easily identifiable physical characteristics. It should be noted that these classifications were and still are being developed mainly by researchers of European origin.
