Races are different ethnic groups of people distinguished by genetic, biological, psychological and cultural characteristics. Identifying race is an important aspect of the study of human diversity and history, and can also help in understanding and solving social and cultural problems. In this article we will look at the main racial characteristics, their characteristics and significance for the study of humanity.
Morphological characters are characteristics that can be determined visually by observing human form and proportions. These include the size and shape of the head, face, hair, skin, tongue, teeth and nails. Morphological differences between races may be due to geographical conditions, climate and nutrition. For example, the round-faced Mongolian peoples have Mongoloid eye sockets, narrow eyelids, dark skin and crescent-shaped ears. The Negroid race has black hair and skin, characteristic thick lips and pointed noses. The Caucasian race is characterized by fair skin, straight hair and oval faces. Human morphology can be determined by biochemical tests such as DNA testing. For example, Indians have greater variability in mitochondrial genetic parameters than other races. These genetic differences may indicate long-term adaptation to different habitats. Other methods used to determine racial traits include genetic markers, dermatoglyphics, and lipid profiles. Genetic markers can show the genetic specificity of populations, while dermatoglyphics can identify different papillary lines and hair growth patterns. Lipid profiles can reveal numerous different constituents of body fat such as palmitol, leucitol, pullulan, cestrione. In addition to morphological characteristics, racial differences are also associated with biological characteristics, including physical characteristics. For example, Negroids have larger lips, straight hair, larger teeth, larger noses, and longer arms relative to other races. Mongoloids are characterized by a smaller nose, thick cheeks and thin lips. Caucasians have a small nose and small ears, and blond hair. However, it is important to note that physical differences between people do not necessarily determine racial differences. Dialects, culture, and many other factors can greatly influence our beliefs about different races. One example of this is variation within white races, where skin, mouth, nose and height can vary significantly. In addition, some peoples may contain characteristics of two or more races, which makes their consideration more complex.
