Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
Carl Linnaeus in the 18th century. Linnaeus used Latin terms to arrange species according to observable similarities and differences in their physical morphology. With recent innovations in molecular biology, the traditional classification system has been made more precise by the possibility of going beyond superficial similarities and mapping similarities and differences between species at the genetic level.
