Animal kingdom classification [taxonomy]

Compare the cat, and actin, and then a cat and a fox. What pair has more common features? Without a doubt: a fox and a cat. So, the cat and the fox by the number of common features can be combined into a group of “close relatives”, and the cat and actin — into a group of “distant relatives”. That is, combining animals in the group, characterized by a certain number of common features, scientists classify them. Classification principles were offered by a great Swedish scientist Carl Linnaeus nearly 300 years ago. However, until now scientists still continue to work on its improvement.

In modern classification, the signs, due to which animals are combined in groups, are the features of their internal and external structure, life processes, the ability to produce viable offspring, etc. The subject of systematics science — is description, naming and classification of animals into groups according to common features. To find out what systematic group owns particular animal, special books — determinants of animals — are used.

To classify organisms — means to identify their belonging to all the main systematic categories.

Animal taxonomy

Animals are studied by one of many biological sciences — zoology. Scientists-zoologists are interested in animals’ structure, life processes, distribution, and variation, etc.

The science of animal taxonomy helps to navigate in a stunning variety of animals that inhabit our planet. Its main task is to describe the types of animals, give them names and determine their place in the system of the organic world. At the same time, scientists are studying not only the taxonomy of modern species, but also that lived in the distant past.

Taxonomy categories

The first major systematic categories were introduced in the XVIII century by a prominent Swedish scientist Carl Linnaeus.

The main systematic categories used in the taxonomy and systematics of plants the animals are similar, except difference in “Division” (plants) and “Phylum” (animals) rank.

This list has only main systematic categories used in the taxonomy. In taxonomy of certain animals groups additional categories are used, such as subkingdom, superclass, suborder, superspecies. As in plant systematics, in taxonomy of animals the basic systematic category is species.
