Linnaean taxonomy is a system of classification that divides all living things into hierarchical groups based on their characteristics. (i.e Living things are divided into groups, the groups are then divided into smaller groups and so on until every living thing has a distinct name due to their distinct characteristics.)
The Linnaean taxonomy hierarchy from top to bottom:
1. domain
2. kingdom
3. phylum
4. class
5. order
6. family
7. genus
8. species
9. subspecies (occasionally used)
Why is so much of it still in use?
The system has been continuously refined over the years with different groups being added when a new discovery is made.
Linnaean taxonomy is still in use because the hierarchical system is very efficient in presenting information.
For example, the Linnaean classification of humans gives much information about our characteristics:
Domain: Eukaryota
We are eukaryotes, which means we belong to organisms that are composed of more than one cell. (unlike prokaryotes)
Family: Animalia
We are animals (as opposed to plants and fungi eukaryotes), which means we have practically all animal features.
Phylum: Chordata
We are vertebrates, which means we have a spine. (Unlike jellyfish and such)
Class: Mammalia
We have mammalian features, which included being warm blooded, giving live births and feeding on milk.
Order: Primates
We have primate features, five fingers, non-specific teeth, binocular vision etc.
Family: Hominidae
Hominid features: no tail, omnivorous diet, nails instead of claws etc.
Genus: Homo
We are the only modern species of the genus homo. Features include bipedalism. Other living things may have several species within the same genus.
Species: Homo sapiens
The unique name given to our species with all the features of the above hierarchy.
Subspecies: Homo sapiens sapiens
Some classify modern humans as this subspecies due to differing classifications of other (extinct) species of the genus homo.
Due to efficient manner the information of living organisms is presented, the Linnaean taxonomy will continue to be used.

ViviThe Linnaeus classification system, also known as the binomial nomenclature system, is a system for naming and organizing living organisms. Developed by Carl Linnaeus in the 18th century, it assigns each species a two-part name consisting of its genus and species. This system helps to categorize organisms based on their shared characteristics and evolutionary relationships.

What was the name of the book in which Linnaeus published the classification system?
The book in which Linnaeus published his classification system was called "Systema Naturae".
What is the largest taxonomic category in Linnaeus's system of classification is?
The largest taxonomic category in Linnaeus's system of classification is the kingdom.
When was the classification system invented?
The first classification system was developed by Aristotle in ancient Greece around 350 BCE. His work laid the foundation for future classification systems, including the modern scientific classification system developed by Carl Linnaeus in the 18th century.
