The fauna, the classification of which meets the requirements of modern science, is striking in its diversity of existing forms. And today, scientists continue to discover new species of living creatures that live on the planet. It is for this reason that zoology needs an order that takes into account the types of animals. It is the correct classification that allows science to develop and move forward.

Systematics

The science of systematics helps to navigate the diversity of species that represent the animal world of the Earth. The classification of animals in certain groups is one of the activities in which it is engaged.

Animal Classification: Systematic GroupsThe newly discovered representatives of the animal world should be described by scientists and placed in the place of the general system where they should be in accordance with the characteristics adopted in the scientific world.

The modern system of distribution of the animal world into groups is based on determining the degree of their kinship, taking into account the origin, the external and internal structure of organisms, the ability to reproduce offspring. Types of animals are located in the table from lower to higher. This corresponds to the general direction of the evolutionary development of the animal world on Earth.

Type - the basic concept of classification

In defining the concept of a species, the structure of the body of animals, their habitat, and the ability to reproduce are taken into account. Associations of individuals with common properties constitute animal species.

The classification of individual species, in turn, can be represented by populations. A feature of the group of animals that make up a particular population is relative isolation from representatives of the same species. The formation of such groups of animals is associated with their permanent habitat.

Karl linney and animal classification

Not always in the academic environment there was a unanimous opinion about the rules for the distribution of representatives of wildlife into certain groups. The current system was proposed by the famous scientist Carl Linnae more than three hundred years ago. It was very convenient and eliminated confusion in cases where scientists had to describe new types of animals.

The classification used today, requires to include in it the names of animals only in Latin. Part of the name consists of two words. The first of these indicates the identity of the animal the genus name is a noun. The second word in the title must be an adjective and to indicate the identity of the animal to species.
Such a classification of animals does not allow to confuse, for example, the gull lake with some other species of birds. Among a huge variety of animals she the only one who has such a name.

Family and family

The group indicating the following system unit used in the case when the classification of animals is carried out is called a genus. It combines related species.

An example is the genus Raven, which includes representatives of such species as the jackdaw, crow, and rook. Close births are grouped into families. For example, a widespread family, called Vranovye. It includes the following genera of birds: raven, jay, magpie, nutcracker.

Troops and classes

The whole animal world, the basis of the classification of which is a species, is grouped into larger groups. These include troops. For example, several families are included in the Sparrow-like detachment: Sinitsevye, Lastochkovye, Vranovye.

Examples of orders can be such names as Sparrows, Owls, Goosebirds. It is easy to guess that the troops are classes of animals. The classification proposed by Karl Linnaeus several centuries ago, refined and improved by modern scientists, rightfully has universal status.

Animal types

All known classes of animals are combined into types. Modern science knows about twenty-five types of animals. An example is such a type as Chord. It consists of classes of Birds, Mammals, Amphibians. All types known to science constitute the animal kingdom. Systematics is not arbitrary. All descriptions of animals and their assignment to a particular group in the classification system have scientific rationale. There are also international standards governing the activities of scientists from around the world.

You must know that the science of taxonomy continues to evolve. Today, scientists agree on the allocation in the General system of categories such as superorder, subtype, subclass. There is a discussion of what place in the system must occupy a single-Celled or Simple. In some textbooks these representatives belong to a special group, representing the types of animals.

The classification allocates multicellular organisms to another large group of animals. Among them are considered the following types: Intestino-flatbone, Flat, Round, Ringed worms. There are other types of animals. For example, the Mollusks type is represented by the class Gastropods, Bivalves, Cephalopods. In the Arthropod type, the classes are Crustaceans, Arachnids, Insects.

Another numerous type of chord includes classes Cartilage and Bone fish, which are combined by scientists in the superclass Pisces. Amphibians, Reptiles, Birds and Mammals are also Chordate. In the most highly organized class of mammals, eleven orders are considered. The animal classification scheme proposed by zoologists is not only filled with specific content, but has a scientific rationale.
