Carl Linnaeus, a Swedish naturalist, botanist, zoologist, and physician, was the founder of modern scientific nomenclature used to label and classify plants and animals. Linnaeus\u2019s designed a system of binomial nomenclature with each element in the system classified and named in terms of its general category or genus and its specific category or species. This led to what was to be known as systematics\u2014a hierarchical organization of species. For example, humans belong to genus \u201chomo\u201d and species \u201csapiens\u201d. Before the invention of binomial classification by Linnaeus, animals were classified according to their mode of movement.<\/p>\n\n\n\n
Linnaeus\u2019s taxonomies consist of three kingdoms, divided into classes, that are subdivided into orders, genera (singular: genus), and species (singular: species).<\/p>\n\n\n\n
Species are subclassified in a ranked hierarchy, starting with domains. Kingdoms are divided into phyla (singular: phylum) \u2014 for animals; the term division, used for plants and fungi, is equivalent to the rank of phylum (and the current International Code of Botanical Nomenclature allows the use of either term). Phyla (or divisions) are divided into classes, and they, in turn, into orders, families, genera (singular: genus), and species (singular: species).<\/p>\n\n\n\n
Linnaeus used his classification system not only to classify animals and plants, but also human diseases.<\/p>\n\n\n\n
Systema Naturae (1735)\u2014in this book Linneaus presents his system of botanical nomenclature which he uses to classify plants, animals and minerals.<\/p>\n\n\n\n
