What are the taxonomic categories of Linnaeus

Carl von Linné (* May 23, 1707, † January 10, 1778)

The Swedish natural scientist Carl von Linné put with his work 'Systema Naturae'' the essential cornerstone for the scientific classification and naming of animal and plant species. First published in 1735, the book only contained a few pages on the three natural kingdoms of minerals, plants and animals (assumed by Linnaeus). The last, 12th edition from 1768, on the other hand, described more than 15,000 animal and plant species. Carl von Linné practically extended his entire life through the 'Systema Naturae', which in large parts is still valid today or serves as a basis.

The classification according to Linnaeus looks like this: rich (Animals, plants, minerals), class (Amphibians, fish, insects, mammals, worms, birds), order, genus, Art and variety. But be careful, because this division is no longer up to date. The highest category for classification is now the domain (archaea, bacteria, eukaryotes). Furthermore, minerals could not assert themselves as a realm of their own. Finally, the variety falls completely out of the currently valid nomenclature.
In the course of history there have been frequent changes to the systematics or the re-classification of species in the systematics. The possibilities for examining relationships for the purpose of precise assignment have increased immensely in recent years. Using DNA analyzes, animals can be brought into contact with their close relatives in a relatively reliable manner. But even if some of Linnaeus' 'Systema Naturae' turned out to be wrong, his oeuvre is probably the most important and groundbreaking work for biology in the 18th and 19th centuries.

In different languages, animals sometimes have completely different names. In order to be able to conduct a scientific discourse on animals and plants at all, each individual species must in principle be given a fixed and globally valid name. Aware of this, Carl von Linné gave each known animal and plant species its own scientific name. For this he chose Latin as the language, the universal language widely used at the time among scholars. To this day, the biological nomenclature for naming and classifying is kept in Latin. This is the only way to ensure that two researchers from different countries with different languages ​​also mean the same living being when they communicate with each other.
By the way, everyone has probably heard the scientific name for us humans: homo sapiens.
