The Linnaean Classification System is a naming scheme used by scientists to identify living things, and to sort them according to their relationships to each other.
The Linnaean Classification System, which is also known as the Linnaean Taxonomy, was invented by a Swedish scientist named Carl Linnaeus [1707-1778].
The main levels of the Linnaean Classification System are: Kingdom, Phylum, Class, Order, Family, Genus, and Species. There are also sub-levels between these main levels.
A mnemonic is something that aids in remembering something else.
A mnemonic phrase that aids in remembering the main levels of the Linnaean Classification System is the phrase Kings Play Chess Often For Good Sport (Kingdom Phylum Class Order Family Genus Species).
According to the Linnaean Classification System, organisms are known by their genus name followed by their species name. The first letter of the genus is capitalized, and the species name is all lower-case. According to this system, humans are known as Homo sapiens.
Another classification system for living things is called cladistics, but more on that later.
