Animal world, the classification of which corresponds to the requirements of modern science, is striking in the variety of existing forms. And today, scientists continue to discover new species of living beings 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 right classification that allows science to develop, move forward.
The science of the taxonomist helps to orient oneself in the variety of species to which the animal world of the Earth is represented. Classification of animals by certain groups is one of the activities that it deals with.
Newly discovered representatives of the animal world should be described by scientists and placed in the place of the common system, where they must be in accordance with the features accepted in the scientific world.
The modern system of distribution of the animal world into groups is constructed on the basis of determining the degree of their kinship, taking into account the origin, external and internal structure of organisms, the ability to reproduce the offspring. The types of animals are located in the table from the lowest to the highest. This corresponds to the general direction of the evolutionary development of the animal kingdom on Earth.
Kind - the basic concept of classification
When determining the concept of a species, the structure of the body of animals, their habitat, and the ability to reproduce are taken into account. The associations of individuals possessing common properties make up the species of animals.
The classification of individual species, in turn, can be represented by populations. A feature of a 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 the place of their permanent habitation.
Carl Linnaeus and the classification of animals
Not always in the academic community there was a common opinion about the rules for the distribution of representatives of wildlife to certain groups. The current system was proposed by the famous scientist Karl Linnaeus more than three hundred years ago. It was very convenient and eliminated confusion in cases where scientists had to describe new species 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
A group indicating the next system unit used when the animals are classified is called genus. It combines close species.
An example is the genus of crows, which includes representatives of such species as jackdaw, crow, rook. Close genera are grouped into families. For example, a family widely known as Vranovs is widespread. It included the following genera of birds: a raven, a jay, forty, a nutcracker.
Detachments and classes
The entire animal world, whose classification is based on species, is grouped into larger groups. These include units. For example, several families are included in the order of the Passeriformes: Sinichevs, Swallows, Vranovs.
Examples of orders can serve as such names as Passeriformes, Owl-shaped, Goose-like. It is easy to guess that the detachments make up the classes of animals. Classification, proposed by Karl Linnaeus several centuries ago, refined and improved by modern scientists, rightly has the status of universal.
Types of animals
All known animal classes are combined into types. Modern science knows about twenty-five types of animals. An example is a type such as Chordovye. It consists of classes of Birds, Mammals, Amphibians. All types known to science form the kingdom of animals. Systematics is not arbitrary. All descriptions of animals and referring them to a particular group in the classification system are subject to scientific justification. There are also international norms governing the activities of scientists from different countries of 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 distinguishes multicellular organisms into another large group of animals. Among them, the following types are considered: Cauchoputal, Flat, Round, Ringworm. There are other types of animals. So, for example, the Mollusca type is represented by the class Gastropoda, Bivalve, Cephalopod. In the type of Arthropods, the classes Crustaceans, Arachnids, Insects are combined.
Another numerous type of Chordates includes classes of Cartilaginous and Bony fishes, which are united by scientists into the Pisces superclass. Amphibians, Reptiles, Birds and Mammals are also of the Chordovye type. In the most highly organized class of mammals, eleven detachments are considered. The animal classification scheme proposed by zoologists is not only filled with concrete content, but has a scientific justification.
