Taxonomy (biology) new common (or apomorphic) traits. However, certain phenetic methods, such as neighbor joining, have found their way into cladistics, as a reasonable approximation of phylogeny when more advanced methods (such as Bayesian inference) are too computationally expensive. Modern taxonomy uses database technologies to search and catalogue classifications and their documentation. While there is no commonly used database, there are comprehensive databases such as the "Catalogue of Life", which attempts to list every documented species. The catalogue listed 1.64 million species for all kingdoms as of April 2016, claiming coverage of more than three quarters of the estimated species known to
Carl Linnaeus difference is of nobility." Linnaeus added a second species to the genus "Homo" in "" based on a figure and description by Jacobus Bontius from a 1658 publication: "Homo troglodytes" ("caveman") and published a third in 1771: "Homo lar". Swedish historian Gunnar Broberg states that the new human species Linnaeus described were actually simians or native people clad in skins to frighten colonial settlers, whose appearance had been exaggerated in accounts to Linnaeus. In early editions of "", many well-known legendary creatures were included such as the phoenix, dragon, manticore, and satyrus, which Linnaeus collected into the catch-all category "Paradoxa".
