His death was on January 10, 1778, Uppsala), and he is considered one of the most important natural scientists and explorers, and he died on January 10, 1778, in Uppsala, one of the most important scientists of Sweden. Linnaeus grew up in Småland, one of the poorest regions in southern Sweden, and his initial interest was in botany. Guided by a teacher in the Växjö gymnasium, who introduced him to the botanical system of the French botanist and physician Joseph Bethune de Turnfort.

Karl's father taught him Latin and geography at a very young age in an effort to prepare him to take up the priesthood when Niels retired. Karl spent two years teaching but did not like the man he had chosen to teach and then went to the Low Grammar School in Vaxjo,Linnaeus wrote his thesis on the sexuality of plants, which earned him a place as a lecturer at the college. He spent most of his life traveling and discovering new types of plants and useful minerals.

Linnaeus' classification: The evolution of life on planet Earth over the past four billion years has led to a huge diversity in the types of living things. For more than two thousand years, scientists have tried to classify this great diversity of life, The classification of living things is one of the important steps in the science (taxonomy) and understanding of the current diversity and the previous evolutionary history of life on Earth, and it should be noted that all classifications are carried out according to the scheme of animal classification. kingdom.

Classification is one of the most important sciences that made it easier for researchers to study living organisms. Classification is hierarchical or hierarchical relational schemes instead of hierarchical schemes. Linnaeus is considered one of the most important modern taxonomists,Modern science focused on taxonomy and made groups of organisms more detailed and accurate in terms of name, characteristics, and species, Many scholars have provided information and observations in classification systems, each of which depends on different bases or complements the journey of previous scholars.

Early in Linnaeus' career, he believed species to be permanent and immutable, as his devout father taught him. However, the more he studied and classified plants, the more he began to see changes in species through crossbreeding.
Linnaeus relied on some principles, including, he used the Latin language in the names of living things, he adopted the binary label in Linnaeus' classification, he used hierarchical levels to classify organisms from species to kingdom.

A well-known example of Linnaeus' classification of organisms is his classification of wolves, gray wolves and coyotes share a long evolutionary history and are closely related, because they belong to the same domain, kingdom, asylum, class, order, family, and genus. Their scientific names indicate that they belong to different species.

Linnaeus came to believe that all living things reproduce sexually, and as a result, he predicted that every plant had both male and female sexual organs (stamens and pistils), or "husbands and wives", and on that basis he designed a simple system of distinguishing features to classify each plant.Scientists have classified the living organisms around them according to the levels of classification followed in the system and network distribution, which are:
Genus, genus, family, order, class, phylum, kingdom.
