The system of classification in which there are seven hierarchies from kingdom to species was introduced by Carolus Linneus. He was a Swedish botanist and zoologist who is known as the "father of modern taxonomy." He developed a system of classification that organized all living things into groups based on their physical characteristics. This system has seven levels, starting with the kingdom and ending with the species. Linneus's system is still widely used today and forms the basis for our modern understanding of the classification of living things. In a simple and comprehensive way, Carolus Linneus introduced the system of classification that organizes living things into seven groups based on their physical characteristics.
