the human race and nation are studied by various scientific disciplines.Thus, ethnic groups studying social science - ethnology.The human race are investigated and physical anthropology, biological science.
human settlement began in ancient times.Groups, learning area, naturally side by side with each other, which is also naturally implies a close, including marital relations.
Mistsegenatsiya (physical mixing) of different groups that began in ancient times, continues today.However, significant changes in the so-called race and made a picture of the world The Great Migration IV-VII centuries.
a result of mixing the races today, almost never occur in pure form.This fact applies to the largest nations (for example, the southern Chinese outwardly indistinguishable from the north), and to a relatively small nation - such as Khakassia, Mansi, Altai, Khanty and other peoples of Siberia, the Urals and the Volga region is shaped by the interaction and MongoloidCaucasoid groups.
South and South-East Asian nations differ in varying degrees of intensity mixing Australoid, Mongoloid and Caucasoid elements.
In South India, the human race represented less varied than in other areas.It is adjacent to a lot of sub-ethnic groups that minimally mixed with each other.It should be said that the improved barriers between groups does not exist, therefore mistsegenatsiya occurs.
After the discovery of America and its subsequent development have formed two fairly large groups: the mulattos and mestizos.Mestizo, commonly referred to as the descendants of Indians and "white" and mulatto - the "white" and Africans.
Australian-Negroid race or equatorial different curly hair, dark skin.The characteristic features include its wide nose, big mouth, thick lips.In this large group includes the following types of races:
- Australian - different wavy hair, dark skin with copious amounts of hair on the body and face.The representatives of this subgroup have above-average growth or high.
- Veddoidnaya race is characterized by a low growth and a small amount of hair.These people have a smaller head and a wide nose.
- representatives of the Melanesian race, including negritosskie types differ strongly developed body hair.Its representatives are also characterized by curly hair, protruding eyebrows strongly enough.
- negroid, unlike veddoidnoy and Australia, has high curly hair.For these people, characterized by thick lips, a relatively higher eye orbit, low tolerated tall.
- Negrillskaya Negroid race is different from the less thick lips, short stature.The representatives of this subgroup more abundant tertiary hair and nose appears sharper.
- Bushmen are not only low growth, but a lighter complexion.Their nose is narrow, the face of relatively flat and has a small size.
It should be noted that some people miscegenation occurred only in antiquity and in the era of the Middle Ages.Others have different nationalities mistsegenatsiya increased intensity is today.
races are primarily reflects the average characteristics of a population of one or the other.At the same time a uniquely human attribute even to the largest group is not always possible.Even among the mulattoes there are different types, in the people who are sometimes combined the most contradictory traits.Small local race, meanwhile, tend to be determined on the basis of statistical data medium.
