Systema Naturae

Systema Naturae is one of the major works of Swedish botanist, zoologist, and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, Linnaeus was the first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis, which appeared in English in 1806 with the title: "A General System of Nature, Through the Three Grand Kingdoms of Animals, Vegetables, and Minerals, Systematically Divided Into their Several Classes, Orders, Genera, Species, and Varieties, with their Habitations, Manners, Economy, Structure and Peculiarities".

Overview
Linnaeus (later known as "Carl von Linné", after his ennoblement in 1761) published the first edition of in 1735, during his stay in the Netherlands. As was customary for the scientific literature of its day, the book was published in Latin. In it, he outlined his ideas for the hierarchical classification of the natural world, dividing it into the animal kingdom (), the plant kingdom (), and the "mineral kingdom" (). Linnaeus's lists only about 10,000 species of organisms, of which about 6,000 are plants and 4,236 are animals. According to the historian of botany William T. Stearn, "Even in 1753, he believed that the number of species of plants in the whole world would hardly reach 10,000; in his whole career, he named about 7,700 species of flowering plants." His sexual system, where species with the same number of stamens were treated in the same group, was convenient, but in his view artificial. The tenth edition expanded on these varieties with behavioral and cultural traits that the Linnean Society acknowledges as having cemented colonial stereotypes and provided one of the foundations for scientific racism. As a result of the popularity of the work, and the number of new specimens sent to him from around the world, Linnaeus kept publishing new and ever-expanding editions of his work. It grew from 11 very large pages in the first edition (1735) to 2,400 pages in the 12th edition (1766–1768). Also, as the work progressed, he made changes; in the first edition, whales were classified as fishes, following the work of Linnaeus' friend and "father of ichthyology" Peter Artedi; in the 10th edition, published in 1758, whales were moved into the mammal class. In this same edition, he introduced two-part names (see binomen) for animal species, which he had done for plant species (see binary name) in the 1753 publication of . The system eventually developed into modern Linnaean taxonomy, a hierarchically organized biological classification. After Linnaeus' health declined in the early 1770s, publication of editions of went in two directions. Another Swedish scientist, Johan Andreas Murray, issued the section separately in 1774 as the , confusingly labelled the 13th edition. Meanwhile, a 13th edition of the entire appeared in parts between 1788 and 1793. It was as the that Linnaeus' work became widely known in England following translation from the Latin by the Lichfield Botanical Society, as A System of Vegetables (1783–1785). == Taxonomy ==
Taxonomy
In his ', Linnaeus established three kingdoms, namely ', ', and '. This approach, the Animal, Vegetable, and Mineral Kingdoms, survives until today in the popular mind, notably in the form of parlour games: "Is it animal, vegetable or mineral?" The classification was based on five levels: kingdom, class, order, genus, and species. While species and genus were seen as God-given (or "natural"), the three higher levels were seen by Linnaeus as constructs. The concept behind the set ranks being applied to all groups was to make a system that was easy to remember and navigate, a task in which most say he succeeded. Linnaeus's work had a huge impact on science; it was indispensable as a foundation for biological nomenclature, now regulated by the Nomenclature Codes. Two of his works, the first edition of the '' (1753) for plants and the 10th edition of the Systema Naturæ (1758), are accepted to be among the starting points of nomenclature. Most of his names for species and genera were published at very early dates and thus take priority over those of other, later authors. Zoology has one exception, which is a monograph on Swedish spiders, '', published by Carl Clerck in 1757, so the names established there take priority over the Linnean names. His exceptional importance to science was less in the value of his taxonomy, but more in his deployment of skillful young students abroad to collect specimens. At the close of the 18th century, his system had effectively become the standard for biological classification. Animals Only in the animal kingdom is the higher taxonomy of Linnaeus still more or less recognizable and some of these names are still in use, but usually not quite for the same groups as used by Linnaeus. He divided the Animal Kingdom into six classes; in the tenth edition (1758), these were: • Mammalia comprised the mammals. In the first edition, whales and the West Indian manatee were classified among the fishes. • Aves comprised the birds. Linnaeus was the first to remove bats from the birds and classify them under mammals. • Amphibia comprised amphibians, reptiles, and assorted fishes that are not of Osteichthyes. • Pisces comprised the bony fishes. These included the spiny-finned fishes (Perciformes) as a separate order. • Insecta comprised all arthropods. Crustaceans, arachnids and myriapods were included as the order "Aptera". • Vermes comprised the remaining invertebrates, roughly divided into "worms", molluscs, and hard-shelled organisms such as echinoderms. Humans Linnaeus was one of the first scientists to classify humans as primates (originally Anthropomorpha for "manlike"), eliciting some controversy for placing people among animals, thus not ruling over nature. He distinguished humans (Homo sapiens) from Homo troglodytes, a species of human-like creatures with exaggerated or non-human characteristics, despite finding limited evidence. The first edition included Europæus albescens (whitish Europeans), Americanus rubescens (reddish Americans), (tawny Asians), and Africanus nigriculus (blackish Africans). It also incorporates behavioral and cultural traits that the Linnean Society recognizes as having cemented colonial stereotypes and provided one of the foundations for scientific racism. == Editions ==
Editions
Gmelin's 13th (decima tertia) edition of Systema Naturae (1788–1793) should be carefully distinguished from the more limited Systema Vegetabilium first prepared and published by Johan Andreas Murray in 1774 (but labelled as "thirteenth edition"). The dates of publication for Gmelin's edition were the following: • Part 1: pp. [1–12], 1–500 (25 July 1788) • Part 2: pp. 501–1032 (20 April 1789) • Part 3: pp. 1033–1516 (20 November 1789) • Part 4: pp. 1517–2224 (21 May 1790) • Part 5: pp. 2225–3020 (6 December 1790) • Part 6: pp. 3021–3910 (14 May 1791) • Part 7: pp. 3911–4120 (2 July 1792) ==See also==
