Taxonomy – the science of organizing or classifying organisms

Animals – Not green

Carolus Linnaeus Made changes to Aristotles’ system 1)Names in Latin, a dead language that will not change 2)Names based on characteristics, the name actually describes the organisms 3)More categories

7 Heirarchies of classification Kingdom Phylum Class Order Family Genus Species (species names are always lowercase) Kings Play Cards On Fine Green Sofas

Species The species name must ALWAYS be lowercase Scientific name is composed of the Genus and species and organism – ex. Homo sapiens The scientific name is better than the common name because it is the same everywhere, there is no error. Linnaeus had 5 Kingdoms, we now have 6. Monera-> Archae + Eu bacteria
