Book of Science

In 1953 Linnaeus published his book species plant arum which is internationally accepted as the starting point of modem botanical nomenclature and in 1958 he released the tenth edition of his book systems nature which established itself as the starting point for zoological nomenclature. He first defined the term genus and species in his book. Based on the observations of size, structure and characteristic, plants and animals are named. On the basis of each other's similarity and dissimilarity, grouping organisms is called classification. The aim of classification is to acquire knowledge of every group and subgroup of each organism. To document the accumulated information systematically focusing on the diversity of living organisms, introduce the total knowledge concisely and take proper steps after identifying organisms to conserve them or increase the number of species for the well-being and the living world are the objectives of classification. Until recently, from the age of Carol's Linnaeus up to the middle of the twentieth venture, all living organisms were classified in one of two kingdoms: Animals and plants. With the progress of science, on the basis of data collected from time to time, for instance, the type of DNA or RNA in a cell, feature and number of cell in a living body and made of nutrition that a cell adopts, a five-kingdom classification was proposed by Whitaker in 1969. Then Masculism introduced a modified and expanded form of Whitaker's classification in 1974. She divided the whole living world into two super-kingdoms and grouped the five kingdoms under these two super-kingdoms.
