What system did Carl Von Linnaeus develop for taxonomy?

Carl Von Linnaeus developed binomial nomenclature, which is the formal system of naming species. This method assigns each species a two-part Latin name consisting of the genus name followed by the species name. This system not only standardizes the naming of organisms but also provides a universal language across different regions and languages, reducing confusion that may arise from local common names.

For example, in binomial nomenclature, humans are referred to as Homo sapiens, where "Homo" is the genus and "sapiens" designates the species. This system allows scientists to communicate more effectively about species, as each name is unique and universally accepted.

Other systems like phylogenetic classification are focused on the evolutionary relationships among species, while a dichotomous key is a tool used for identifying organisms based on a series of choices that lead the user to the correct name of a given item. An ecological hierarchy organizes biological entities in layers based on interaction and complexity, but it is not a naming system. Thus, binomial nomenclature is distinct and foundational in the field of taxonomy.
