The current appearance of humanity is the result of a complex historical development of human groups and can be described by highlighting special biological types - human races. It is assumed that their formation began to occur 30-40 thousand years ago, as a result of the settlement of people in new geographical zones. According to researchers, their first groups moved from the region of modern Madagascar to South Asia, then Australia, a little later on Far East, to Europe and America. This process gave rise to the original races from which all subsequent diversity of peoples arose. As part of the article, it will be considered which main races are distinguished within the species Homo sapiens(reasonable person), their characteristics and features.

Race Meaning

To summarize the definitions of anthropologists, a race is a historically established set of people who have a common physical type (skin color, structure and hair color, skull shape, etc.), the origin of which is associated with a certain geographical area. At the present time, the relation of race to area is not always revealed quite clearly, but it definitely took place in the distant past.

The origin of the term "race" is not reliably defined, but there has been much debate in scientific circles over its use. In this regard, initially the term was ambiguous and conditional. There is an opinion that the word represents a modification of the Arabic lexeme ras - head or beginning. There is also every reason to believe that this term may be related to the Italian razza, which means "tribe". Interestingly, in modern meaning given word first found in the writings of the French traveler and philosopher Francois Bernier. In 1684 he gives one of the first classifications of the major human races.

races

Attempts to put together a picture classifying the human races were made by the ancient Egyptians. They identified four types of people according to their skin color: black, yellow, white, and red. And for a long time this division of mankind persisted. The Frenchman Francois Bernier tried to give a scientific classification of the main types of races in the 17th century. But more complete and constructed systems appeared only in the twentieth century.

It is known that there is no generally accepted classification, and all of them are rather conditional. But in the anthropological literature most often refer to Ya. Roginsky and M. Levin. They identified three large races, which in turn are divided into small ones: Caucasoid (Eurasian), Mongoloid and Negro-Australoid (Equatorial). When constructing this classification, scientists took into account morphological similarities, the geographical distribution of races and the time of their formation.

Race characteristics

Classical racial characteristics are defined by a set of physical features related to appearance man and his anatomy. The color and shape of the eyes, the shape of the nose and lips, the pigmentation of the skin and hair, the shape of the skull are the primary racial features. There are also minor features such as physique, height and proportions of the human body. But in view of the fact that they are very variable and depend on environmental conditions, they are not used in racial science. Racial traits are not interconnected by one or another biological dependence, therefore they form numerous combinations. But it is stable traits that make it possible to distinguish races high order(major), while minor races are distinguished on the basis of more variable indicators.

Thus, the main characteristic of a race includes morphological, anatomical and other features that have a stable hereditary nature and are minimally influenced by environment.

Caucasian race

Almost 45% of the world's population are Caucasians. Geographic discoveries America and Australia allowed her to settle around the world. However, its main core is concentrated within Europe, the African Mediterranean and southwestern Asia.

In the Caucasoid group, the following combination of signs is distinguished:

• clearly profiled face;
• pigmentation of hair, skin and eyes from the lightest to darkest shades;
• straight or wavy soft hair;
• medium or thin lips;
• narrow nose, strongly or moderately protruding from the plane of the face;
• poorly formed fold of the upper eyelid;
• developed hairline on the body;
• large hands and feet.

The composition of the Caucasoid race is distinguished by two large branches - northern and southern. The northern branch is represented by Scandinavians, Icelanders, Irish, British, Finns and others. South - Spaniards, Italians, southern French, Portuguese, Iranians, Azerbaijanis and others. All the differences between them are in the pigmentation of the eyes, skin and hair.

Mongoloid race

The formation of the Mongoloid group has not been fully explored. According to some assumptions, the nationality was formed in the central part of Asia, in the Gobi desert, which was distinguished by its harsh sharply continental climate. As a result, representatives of this race of people generally have strong immunity and good adaptation to cardinal changes in climatic conditions.

Signs of the Mongoloid race:

• brown or black eyes with a slanted and narrow slit;
• overhanging upper eyelids;
• moderately extended nose and lips of medium size;
• skin color from yellow to brown;
• straight coarse dark hair;
• strongly protruding cheekbones;
• poorly developed body hair.

The Mongoloid race is divided into two branches: the northern Mongoloids (Kalmykia, Buryatia, Yakutia, Tuva) and southern peoples(Japan, residents of the Korean Peninsula, South China). Ethnic Mongols can act as prominent representatives of the Mongoloid group.

The equatorial (or Negro-Australoid) race is a large group of people that makes up 10% of humanity. It includes Negroid and Australoid groups, which mostly live in Oceania, Australia, the tropical zone of Africa and in the regions of South and Southeast Asia.

Most researchers consider the specific characteristics of a race as a result of the development of a population in a hot and humid climate:

• dark pigmentation of the skin, hair and eyes;
• coarse curly or wavy hair;
• the nose is wide, slightly protruding;
• thick lips with a significant mucous part;
• protruding lower face.

The race is distinctly divided into two trunks - eastern (Pacific, Australian and Asian groups) and western (African groups).

Minor races

The main races in which humanity has been successfully imprinted on all continents of the earth, branching out into a complex mosaic of people - small races (or races of the second order). Anthropologists distinguish from 30 to 50 such groups. The Caucasoid race consists of the following types: White Sea-Baltic, Atlanto-Baltic, Middle Caucasoid, Balkan-Caucasian (Ponto-Zagros) and Indo-Mediterranean.

The Mongoloid group distinguishes: Far Eastern, South Asian, North Asian, Arctic and American types. It is worth noting that the last of them, in some classifications, is considered to be an independent large race. In today's Asia, the Far Eastern (Koreans, Japanese, Chinese) and South Asian (Javanese, Probes, Malays) types are most prevalent.

The equatorial population is divided into six small groups: the African Negroids are represented by the Negro, Central African and Bushman races, the Oceanian Australoids are the Veddoid, Melanesian and Australian (in some classifications it is put forward as the main race).

mixed race

In addition to races of the second order, there are also mixed and transitional races. Presumably, they were formed from ancient populations within the boundaries of climatic zones, through contact between representatives of different races, or appeared during long-distance migrations, when it was necessary to adapt to new conditions.

Thus, there are Euro-Mongoloid, Euro-Negroid and Euro-Mongol-Negroid sub-races. For example, the Laponoid group has signs of three main races: prognathism, prominent cheekbones, soft hair, and others. The carriers of such characteristics are the Finno-Permian peoples. Or Ural which is represented by Caucasoid and Mongoloid populations. She is characterized by the following dark straight hair, moderate skin pigmentation, brown eyes, and medium hairline. Mostly distributed in Western Siberia.

• Until the 20th century, there were no representatives of the Negroid race in Russia. In the USSR, during the cooperation with developing countries, about 70 thousand blacks remained to live.
• Only one Caucasian race is capable of producing lactase throughout its life, which is involved in the absorption of milk. In the other major races, this ability is observed only in infancy.
• Genetic studies have determined that the fair-skinned inhabitants of the northern territories of Europe and Russia have about 47.5% of Mongolian genes and only 52.5% of European ones.
• A large number of people who self-identify as pure African Americans have European ancestry. In turn, Europeans can find Native Americans or Africans in their ancestors.
• The DNA of all the inhabitants of the planet, regardless of external differences (skin color, hair texture), is 99.9% the same, therefore, from the standpoint of genetic research, the existing concept of "race" loses its meaning.

A great contribution to the description of human races was made by the Soviet scientist Valery Pavlovich Alekseev (1929-1991). In principle, we are now guided precisely by his calculations in this interesting anthropological issue. So what is race?

It's relatively stable biological characteristic kind of people. They are united by a common appearance and psychophysical characteristics. At the same time, it is important to understand that this unity does not in any way affect the form of the hostel and the ways of living together. General signs are purely external, anatomical, but they cannot be used to judge the intellect of people, their ability to work, live, engage in science, art and other mental activities. That is, representatives of different races in their own way mental development absolutely the same. They also have exactly the same rights, and, consequently, duties.

Ancestors modern man are Cro-Magnons. It is assumed that their first representatives appeared on Earth 300 thousand years ago in Southeast Africa. As the millennia passed, our distant ancestors spread throughout the world. They lived in different climatic conditions, and therefore acquired strictly specific biological characteristics. A single habitat gave rise to and common culture. And within this culture ethnic groups were formed. For example, the Roman ethnic group, the Greek ethnic group, the Carthaginian ethnic group and others.

human races subdivided into Caucasoids, Negroids, Mongoloids, Australoids, Americanoids. There are also sub-races or minor races. Their representatives have their own specific biological traits that other people do not have.

1 - Negroid, 2 - Caucasoid, 3 - Mongoloid, 4 - Australoid, 5 - Americanoid

Caucasians - white race

The first Europeans appeared in Southern Europe and North Africa. From there they spread throughout the European continent, got into the Middle, Central Asia and northern Tibet. They crossed the Hindu Kush and ended up in India. Here they settled the entire northern part of Hindustan. They also mastered the Arabian Peninsula and the northern regions of Africa. In the 16th century, they crossed the Atlantic and populated almost the entire North America and most of South America. Then it was the turn of Australia and South Africa.

Negroids - black race

Negroids or Negroes are considered the indigenous inhabitants of the tropical zone. This explanation is based on melanin, which gives the skin its black color. It protects the skin from the burns of the scorching tropical sun. No doubt, it prevents burns. But what clothes do people wear on a hot sunny day - white or black? Of course white, because it reflects the sun's rays well. Therefore, in extreme heat, it is unprofitable to have black skin, especially with high insolation. From this we can assume that the Negroes appeared in those climatic conditions where cloudiness prevailed.

Indeed, the oldest finds of Grimaldi (Negroids), belonging to the Upper Paleolithic, were discovered on the territory of Southern France (Nice) in the Grimaldi cave. In the Upper Paleolithic, this entire area was inhabited by people with black skin, woolly hair and large lips. They were tall, slender, long-legged hunters of large herbivores. But how did they end up in Africa? In the same way that Europeans got to America, that is, they moved there, pushing indigenous people.

What's interesting is that South Africa was inhabited by Negroids - Bantu Negroes (classic Negroes that we know) in the 1st century BC. e. That is, the pioneers were contemporaries of Julius Caesar. It was at this time that they settled in the forests of the Congo, savannas East Africa, reached the southern regions of the Zambezi River and ended up on the banks of the muddy Limpopo River.

And who did these black-skinned European conquerors displace? After all, someone lived before them on these lands. This is a special southern race, which is conditionally called " Khoisan".

Khoisan race

It includes Hottentots and Bushmen. They differ from blacks in brown skin and Mongoloid features. They have a different throat. They do not pronounce words on the exhale, like all of us, but on the inhale. They are considered the remnants of some ancient race that inhabited for a very long time. Southern Hemisphere. There are very few of these people left, and in the ethnic sense, they do not represent anything integral.

Bushmen- quiet and calm hunters. They were pushed out by Bichuani Negroes into the Kalahari Desert. That's where they live, forgetting their ancient and rich culture. They have art, but it is in a rudimentary state, since life in the desert is very difficult and you have to think not about art, but about how to get food.

Hottentots(the Dutch name of the tribes), who lived in the Cape Province (South Africa), became famous for being real robbers. They stole cattle. They quickly became friends with the Dutch and became their guides, translators and farm workers. When the British captured the Cape Colony, the Hottentots made friends with them. They live on these lands to this day.

australoids

Australoids are also called Australians. How they got to the lands of Australia is unknown. But they were there a long time ago. It was great amount small tribes with different customs, rituals and culture. They did not like each other and practically did not communicate.

Australoids are not similar to Caucasoids, Negroids and Mongoloids. They only look like themselves. Their skin is very dark, almost black. The hair is wavy, the shoulders are wide, and the reaction is extremely fast. Relatives of these people live in South India on the Deccan Plateau. Maybe from there they sailed to Australia, and also settled all the islands nearby.

Mongoloids - yellow race

Mongoloids are the most numerous. They are divided into a large number of subraces or minor races. There are Siberian Mongoloids, North Chinese, South Chinese, Malay, Tibetan. What they have in common is a narrow slit of the eyes. The hair is straight, black and coarse. The eyes are dark. The skin is swarthy, has a slight yellowish tint. The face is broad and flattened, the cheekbones protrude.

americanoids

Americanoids populate America from the tundra to Tierra del Fuego. Eskimos do not belong to this race. They are alien people. The hair of the Americanoids is black and straight, the skin is swarthy. The eyes are black and narrower than those of Caucasians. These people have a huge number of languages. Among them, it is even impossible to make any classification. There are many dead languages ​​now, as their speakers have died out and the languages ​​have been written down.

Pygmies and Caucasians

pygmies

Pygmies belong to the Negroid race. They live in the forests of equatorial Africa. Notable for their small stature. They have it 1.45-1.5 meters. The skin has Brown color, lips are relatively thin, hair is dark and curly. Living conditions are poor, hence the small growth, which is the result of a small amount of vitamins and proteins necessary for the body for normal development. Currently, short stature has become a genetic heredity. Therefore, even if the pygmy babies are heavily fed, they will not become tall.

Thus, we have considered the main human races that exist on Earth. But it should be noted that race has never been of decisive importance for the formation of culture. It is also noteworthy that over the past 15 thousand years, no new biological types of people have appeared, and the old ones have not disappeared. Everything is still stable. The only thing is that there is a mixing of people of different biological types. There are mestizos, mulattos, sambo. But these are not biological and anthropological, but social factors determined by the achievements of civilization..

In modern humanity, there are three main races: Caucasoid, Mongoloid and Negroid. These are large groups of people who differ in some physical features, such as facial features, skin color, eyes and hair, hair shape.

Each race is characterized by the unity of origin and formation in a certain territory.

The Caucasian race includes the indigenous population of Europe, South Asia and North Africa. Caucasians are characterized by a narrow face, a strongly protruding nose, and soft hair. The skin color of northern Caucasians is light, while that of southern Caucasians is predominantly swarthy.

The Mongoloid race includes the indigenous population of Central and East Asia, Indonesia, and Siberia. Mongoloids are distinguished by a large flat wide face, slit eyes, hard straight hair, dark skin color.

In the Negroid race, two branches are distinguished - African and Australian. The Negroid race is characterized by dark skin color, curly hair, dark eyes, a wide and flat nose.

Racial characteristics are hereditary, but at present they are not essential for human life. Apparently, in the distant past, racial traits were useful for their owners: the dark skin of blacks and curly hair, creating an air layer around the head, protected the body from the action of sunlight, the shape of the facial skeleton of the Mongoloids with a larger nasal cavity, perhaps, is useful for heating cold air before it enters the lungs. By mental capacity, i.e., abilities for cognition, creative and labor activity in general, all races are the same. Differences in the level of culture are associated not with the biological characteristics of people of different races, but with the social conditions for the development of society.

The reactionary essence of racism. Initially, some scholars confused the level social development with biological characteristics and tried to find transitional forms among modern peoples that connect man with animals. These mistakes were used by the racists, who began to talk about the alleged inferiority of some races and peoples and the superiority of others in order to justify the merciless exploitation and direct destruction of many peoples as a result of colonization, the seizure of foreign lands and the outbreak of wars. When European and American capitalism tried to conquer the African and Asian peoples, the white race was declared the highest. Later, when the Nazi hordes marched across Europe, destroying the captured population in the death camps, the so-called Aryan race was declared the highest, to which the Nazis ranked the German peoples. Racism is a reactionary ideology and politics aimed at justifying the exploitation of man by man.

The failure of racism is proved by the real science of races - racial science. Racial science studies racial characteristics, the origin, formation and history of human races. The data obtained by racial science indicate that the differences between races are not sufficient to consider races as different biological species of people. Mixing of races - miscegenation - occurred constantly, as a result of which intermediate types arose at the boundaries of the ranges of representatives of different races, smoothing out the differences between races.

Will races disappear? One of the important conditions for the formation of races is isolation. In Asia, Africa and Europe, it still exists to some extent today. Meanwhile, newly settled regions such as Northern and South America, can be compared to a cauldron in which all three racial groups are melted down. Although public opinion in many countries does not support interracial marriages, there is little doubt that racial interbreeding is inevitable and will sooner or later lead to the formation of a hybrid human population.

Lesson Plan

1. What human races do you know?
2. What factors cause the evolutionary process?
3. What influences the formation of the gene pool of a population?

What are human races?

Human predecessors are Australopithecus;
- ancient people- progressive australopithecines, archanthropes (pithecanthropes, synanthropes, Heidelberg man, etc.);
- ancient people - paleoanthropes (Neanderthals);
- fossil people of the modern anatomical type - neoanthropes (Cro-Magnons).

The historical development of man was carried out under the influence of the same factors of biological evolution as the formation of other types of living organisms. However, a person is characterized by such a unique phenomenon for wildlife as an increasing influence on the anthropogenesis of social factors ( labor activity, social way of life, speech and thinking).

For a modern person, social and labor relations have become leading and determining.

As a result of social development Homo sapiens has acquired unconditional advantages among all living beings. But this does not mean that the emergence of the social sphere canceled the action of biological factors. Social sphere only changed their expression. Homo sapiens as a species is integral part biosphere and the product of its evolution.

These are historically formed groupings (groups of populations) of people, characterized by the similarity of morphological and physiological features. Racial differences are the result of people's adaptation to certain conditions of existence, as well as the historical and socio-economic development of human society.

There are three large races: Caucasoid (Eurasian), Mongoloid (Asian-American) and Australo-Negroid (Equatorial).

Fundamentals of ecology

After reading this chapter, you will learn:

What does ecology study and why does every person need to know its basics;
- what is the significance of environmental factors: abiatic, biotic and anthropogenic;
- what role do the conditions of the external environment and the internal properties of the population group play in the processes of change in its size over time;
- about different types of interactions of organisms;
- about the features of competitive relations and factors that determine the outcome of competition;
- on the composition and basic properties of the ecosystem;
- about energy flows and the circulation of substances that ensure the functioning of systems, and about the role in these processes

Even in the middle of the XX century. the word ecology was known only to specialists, but now it has become very popular; most often it is used, speaking about the unfavorable state of the nature around us.

Sometimes this term is used in combination with words such as society, family, culture, health. Is ecology really such a vast science that it can cover most of the problems facing humanity?

Human races are biological subdivisions of the Homo sapiens species, historically formed in the evolution of man. They differ in complexes of hereditarily transmitted and gradually changing morphological, biochemical and other features. Race-occupied modern geographical areas distributions, or areas, make it possible to outline the territories in which races were formed. Due to public nature human races are qualitatively different from subspecies of wild and domestic animals.

If for wild animals the term "geographical races" can be applied, then in relation to man it has largely lost its meaning, since the connection of human races with the original areas is broken by numerous migrations of masses of people, as a result of which there was a mixing of the most diverse races and peoples and formed new human associations.

Most anthropologists divide humanity into three large races: Negroid-Australoid ("black"), Caucasoid ("white") and Mongoloid ("yellow"). Using geographical terms, the first race is called the Equatorial, or African-Australian, the second, the European-Asian, the third, the Asian-American race. There are the following branches of large races: African and Oceanian; northern and southern; Asian and American (G. F. Debets). The population of the Earth is now over 3 billion 300 million people (data for 1965). Of these, the first race accounts for approximately 10% of the second - 50% and the third - 40%. This is, of course, a rough total count, since there are hundreds of millions of racially mixed individuals, numerous minor races, and mixed (intermediate) racial groups, including those of ancient origin (eg Ethiopians). Large, or primary, races, occupying vast territories, are not completely homogeneous. They are divided according to physical (bodily) characteristics into branches, into 10-20 small races, and those into anthropological types.

Modern races, their origin and systematics are studied by ethnic anthropology (racial science). Population groups are subjected to research for survey and quantitative definition of so-called racial signs with the subsequent processing of mass data by methods of variation statistics (see). Anthropologists use for this scale the color of the skin and the iris of the eyes, the color and shape of the hair, the shape of the eyelid, nose and lips, as well as anthropometric instruments: compasses, goniometer, etc. (see Anthropometry). Hematological, biochemical and other examinations are also conducted.

Belonging to a particular racial division is determined on men 20-60 years old according to a complex of genetically stable and sufficiently characteristic features physical structure.

Further descriptive features of the racial complex: the presence of a beard and mustache, the stiffness of the hair of the head, the degree of development of the upper eyelid and its fold - the epicanthus, the slope of the forehead, the shape of the head, the development of the superciliary ridges, the shape of the face, the growth of hair on the body, the type of addition (see Habitus) and body proportions (see Constitution).

Options for the shape of the skull: 1 - dolichocranial ellipsoid; 2 and 3 - brachycranial (2 - round, or spheroid, 3 - wedge-shaped, or sphenoid); 4 - mesocranial pentagonal, or pentagonoid.

A unified anthropometric examination on a living person, as well as on the skeleton, mostly on the skull (Fig.), allows you to clarify somatoscopic observations and make a more correct comparison of the racial composition of tribes, peoples, individual populations (see) and isolates. Racial characters vary and are subject to sexual, age, geographical and evolutionary variability.

The racial composition of humanity is very complex, which to a large extent depends on the mixing (miscegenation) of the population of many countries in connection with ancient migrations and modern mass migrations. Therefore, on the land area inhabited by mankind, contact and intermediate racial groups are found, formed from the interpenetration of two or three or more complexes of racial features during the miscegenation of anthropological types.

The process of racial miscegenation greatly increased in the era of capitalist expansion after the discovery of America. As a result, for example, Mexicans are half-mestizo between Indians and Europeans.

A noticeable increase in interracial mixing is observed in the USSR and other socialist countries. This is the result of the elimination of all kinds of racial barriers on the basis of correct scientifically based national and international policies.

The races are biologically equivalent and related by blood. The basis for this conclusion is the doctrine developed by Charles Darwin about monogenism, that is, about the origin of man from one species of ancient bipedal apes, and not from several (the concept of polygenism). Monogenism is confirmed by the anatomical similarity of all races, which, as Charles Darwin emphasized, could not have arisen through convergence, or convergence of characters, of different ancestral species. The species of monkeys that served as an ancestor for humans probably lived in South Asia, from where the most ancient people settled on the Earth. Ancient people, the so-called Neanderthals (Homo neanderthalensis), gave rise to "reasonable man." But modern races did not originate from Neanderthals, but were formed anew under the influence of a combination of natural (including biological) and social factors.

The formation of races (racial genesis) is closely connected with anthropogenesis; both processes are the result of historical development. Modern man arose over a vast territory, approximately from the Mediterranean to Hindustan or somewhat more. From here, Mongoloids could form in the northeast direction, Caucasoids in the northwest, and Negroids and Australoids in the south. However, the problem of the ancestral home of modern man is still far from being fully resolved.

In more ancient eras, when people settled on Earth, their groups inevitably fell into conditions of geographic and, consequently, social isolation, which contributed to their racial differentiation in the process of interaction of factors of variability (see), heredity (see) and selection. With an increase in the abundance of the isolate, a new settlement occurred and contacts with neighboring groups arose, which caused miscegenation. In the formation of races, a certain role was played by natural selection, the influence of which, with the development of the social environment, noticeably weakened. In this regard, the signs modern races are of secondary importance. Aesthetic or sexual selection also played a certain role in the formation of races; sometimes racial features could acquire the value of identifying features for representatives of one or another local racial group.

As the human population grew, both the specific significance and the direction of action of individual factors of racial genesis changed, but the role social influences increased. If for the primary races miscegenation was a differentiating factor (when the miscegenated groups again fell into conditions of isolation), now mixing levels out racial differences. Currently, about half of humanity is the result of miscegenation. Racial differences that have naturally arisen over long millennia must be and will be, as K. Marx pointed out, eliminated historical development. But racial traits will manifest themselves for a long time in various combinations, mainly in individuals. Cross-breeding often causes the emergence of new positive features of the physical warehouse and intellectual development.

The race of the patient must be taken into account when evaluating some of the findings of the medical examination. This applies mainly to the features of the color of the integument. The color of the skin, characteristic of a representative of the "black" or "yellow" race, in the "white" will turn out to be a symptom of Addison's disease or icterus; the purple tint of the color of the lips, the bluish nails of the Caucasoid, the doctor will evaluate as cyanosis, in the Negro - as a racial feature. On the other hand, color changes in "bronze disease", jaundice, cardio-respiratory failure, distinct in Caucasians, can be difficult to determine in representatives of the Mongoloid or Negroid-Australoid race. Much less practical value have, and less often may require, corrections for racial characteristics in assessing the physique, height, shape of the skull, etc. As for the alleged predisposition of a given race to a particular disease, increased susceptibility to infection, etc., these features, as as a rule, they do not have a “racial” character, but are associated with social, cultural and other living conditions, the proximity of natural foci of infection, the degree of acclimatization during resettlement, etc.
