Carl Linnaeus was the Swedish scientist who formulated the modern classification system used for naming organisms.
Born in 1707, Linnaeus developed a hierarchical system that grouped organisms into categories such as genus and species. His two-part naming method, or binomial nomenclature, gave each species a standardized Latin name. This made it easier for scientists in different countries to communicate about the same organism.
Linnaeus did not discover every species he named, and modern biology has revised many of his groupings using evolutionary and genetic evidence. Nevertheless, his naming framework remains foundational. His best-known work, Systema Naturae, was first published in 1735 and expanded through multiple editions. The scientific name Homo sapiens follows the binomial pattern he helped establish.
