The Modern Taxonomic System ,[object Object],[object Object],[object Object],2 kingdoms by Swedish botanist Carolus Linnaeus (1707–1778) Linnaeus wrote a huge encyclopedia of life “ Systema Naturae” (system of nature), containing all living things at that time. PLANTS ( Regnum Vegetabile) ANIMALS (Regnum Animale)

Historically, the number of kingdoms in widely accepted classifications has grown from two to six. However, phylogenetic research from about 2000 onwards does not support any of the traditional systems.

Archaea live in harsh environments and may represent the first cells to have evolved. Sewage treatment plants, thermal vents, etc.

Eubacteria, some of which cause human diseases, are present in almost all habitats on earth. Many bacteria are important environmentally and commercially. Live in the intestines of animals
