explain the major races with their physical traits and global distribution.
Answers
Explanation:
Race as an expression has been used in different contexts, viz. culture, tradition, language and nationality.
There has been some difference of opinion regarding the origin of different races. One school of thought argues that racial differences existed from the very beginning, while another school of thought believes that different races developed from one single ancestral species.
The scientific classification of human racial types is based on certain combinations of fixed, inherited, as far as possible measurable and visually identifiable traits, such as head shape, facial features, nose shape, eye shape and colour, skin colour, stature, blood groups etc. These traits represent morphological, biological and genetical aspects. With the inclusion of more and more traits, the number of combinations increases and the analysis becomes more complex.There is no single way of classifying mankind into biological races. In the past, physical characteristics, such as skin colour and hair type, were used to delineate three to five biological races (Caucasoid, Negroid and Mongoloid and later, Australoid and American Indian).
More subtle techniques, taking into account blood types and hereditary diseases as well as terrain barriers, result in classifications that may include as many as eight or nine geographical races.
Although difference of opinion exists regarding terminology and the exact classification, the following divisions are generally accepted:
1. Caucasoid (European)
2. Negroid (African)
3. Mongoloid (Asiatic or Oriental)
4. Indie (Hindu)
5. Australoid (Australian aboriginals)
