race,

one of the group of populations regarded as constituting humanity. The differences that have historically determined the classification into races are predominantly physical aspects of appearance that are generally hereditary. Genetically a race may be defined as a group with gene frequencies differing from those of the other groups in the human species (see heredityheredity,

), but the genes responsible for the hereditary differences between the traditional races are extremely few when compared with the vast number of genes common to all human beings regardless of the race to which they belong. Many physical anthropologists now believe that, because there is as much genetic variation among the members of any given race as there is between the groups identified as different races, the concept of race is unscientific and unsound and racial categories are arbitrary designations. The term race is inappropriate when applied to national, religious, geographic, linguistic, or ethnic groups, nor can the physical appearances associated with race be equated with mental characteristics, such as intelligence, personality, or character.

All human groups belong to the same species (Homo sapiens) and are mutually fertile. Races arose as a result of mutationmutation,

, selection, and adaptational changes in human populations. The nature of genetic variation in human beings indicates there has been a common evolution for all races and that racial differentiation occurred relatively late in the history of Homo sapiens. Theories postulating the very early emergence of racial differentiation have been advanced (e.g., C. S. CoonCoon, Carleton Stevens,

Attempts at Classification

To classify humans on the basis of physical traits is difficult, for the coexistence of races through conquests, invasions, migrations, and mass deportations has produced a heterogeneous world population. Nevertheless, by limiting the criteria to such traits as skin pigmentation, color and form of hair, shape of head, stature, and form of nose, most anthropologists historically agreed on the existence of three relatively distinct groups: the Caucasoid, the Mongoloid, and the Negroid.

The Caucasoid, found in Europe, N Africa, and the Middle East to N India, is characterized as pale reddish white to olive brown in skin color, of medium to tall stature, with a long or broad head form. The hair is light blond to dark brown in color, of a fine texture, and straight or wavy. The color of the eyes is light blue to dark brown and the nose bridge is usually high.

The Mongoloid race, including most peoples of E Asia and the indigenous peoples of the Americas, has been described as saffron to yellow or reddish brown in skin color, of medium stature, with a broad head form. The hair is dark, straight, and coarse; body hair is sparse. The eyes are black to dark brown. The epicanthic fold, imparting an almond shape to the eye, is common, and the nose bridge is usually low or medium.

The Negroid race is characterized by brown to brown-black skin, usually a long head form, varying stature, and thick, everted lips. The hair is dark and coarse, usually kinky. The eyes are dark, the nose bridge low, and the nostrils broad. To the Negroid race belong the peoples of Africa south of the Sahara, the Pygmy groups of Indonesia, and the inhabitants of New Guinea and Melanesia.

Each of these broad groups can be divided into subgroups. General agreement is lacking as to the classification of such people as the aborigines of Australia, the Dravidian people of S India, the Polynesians, and the Ainu of N Japan within the traditional three race system. These exceptions highlight the problems associated with attempting to classify humanity into races and also challenge the validity of the notion of race when applied to human beings.

Race Classification and Racism

Attempts have been made to classify humans since the 17th cent., when scholars first began to separate types of flora and fauna. Johann Friedrich BlumenbachBlumenbach, Johann Friedrich

race

a scientifically discredited term previously used to describe biologically distinct groups of persons who were alleged to have characteristics of an unalterable nature. The concept has been used in the English language since the 16th-century Its meaning has altered several times over the last 400 years in line with changing concepts about the nature of physical and cultural differences and, more importantly the ideological uses of the concept to justify relationships of superiority and exploitation. Banton in Racial Theories (1987) provides a comprehensive account of the different uses of the concept of race.

Social scientists now recognize that ‘race’ is exclusively a socially constructed categorization which specifies rules for identification of a given group. Many writers will not use the term except in inverted commas to distance the use of the word from its historical and biological connotations. It is preferable to refer to ETHNICITY or ETHNIC GROUPS. Despite the discredited nature of the concept of’race’, the idea still exerts a powerful influence in everyday language and ideology. See also RACE RELATIONS, RACISM, ETHNICITY, ETHNIC GROUP.

Race

 

in biology, an ecologically or sometimes geographically related group of organisms within a species or subspecies.

The members of a race have similar morphological, physiological, and ecological characteristics and are distributed in a region that is part of the range of the species or subspecies. Various races are often found in the same locality, but they are differentiated by their living conditions (ecological race). Thus, many plant species include an alpine race, a xeromorphic race, and a race that requires shade. Among animals, there are seasonal races of crustaceans. Many races of parasites are distinguished by their functional adaptation (specialization) to certain plant or animal hosts (races based on hosts). In ichthyology the term “race” refers to local populations (schools) of fish.

Sometimes, geographic races are regarded as subspecies. The term “race” is also used with reference to breeds of domesticated animals.

What does it mean when you dream about a race?

Running a race may depict how the dreamer feels about his or her waking life (a hectic “rat race,” perhaps?), possibly indicating the dreamer should slow down or change his or her approach to life.

The units read and wrote data on a deck of 4x18" cards with a magnetic recording surface. The card was released from the cartridge, passed down a raceway, wrapped around a read/write head and returned. Operating in the late 1960s, the machine jammed frequently, and an operator had to remain nearby to extricate and replace the damaged cards. See CRAM, Data Cell and racetrack memory.

Race

(dreams)
Are you competing or running from or to something? In order to have a good understanding of this dream you should consider those factors. If you are simply running, it may be an indication that you need to slow down in your everyday life. If you are competing, you need to consider your competitive drive and realistically look at the current challenges. If you are running in a race and win, your unconscious may be expressing confidence that you may or may not feel in the wakened state. Running in your dreams may also symbolize the energy levels, the strength, or the force that you have to get through life.
