2. Classification… Before the 1600’s many scientists believed that all organisms were either plants or animals With the invention of the microscope and discovery of more organisms the classification and organization became more complex In the 1700’s a Swedish scientist, Carolus Linnaeus founded what is modern day taxonomy ~ the science of describing, classifying, and naming living things

3. Why Classify? Scientists classify organisms to help make sense and order the many different kinds of living things in the world Classification helps scientist to answers important questions such as: How many species are there? What are their defining characteristics of each species? What are the relationships between these different species? There is a specific system scientists use to classify organisms based on the characteristics that they share

4. 8 Level of Classification Domain: The largest and most general. Archaea, Bacteria, and Eukarya All living things in the domains are then separated into Kingdoms, Phylum, Class, Order, Family, Genus, and finally, the most fundamental, Species K ing P hilip C ame O ver F or G ood S oup

5. Binomial Nomenclature Linnaeus also made it simple to name each individual organism by giving them a 2-part scientific name Advantages of scientific naming over common names: Accepted by all languages Only one name for each species Each species only has one name

6. The 1 st part of the name is genus name (ALWAYS CAPITALIZED) The 2 nd part is the species name **Example: Asian elephant is Elephas maximus **Tryannosaurus rex ***Scientific name is ALWAYS either italicized or underlined*** Genus : A grouping of similar species For Example: the domestic cat and bobcat are in the same genus: Felis Dogs, wolves, and jackals belong to Canis Species: Fundamental unit of classification Consist of populations of genetically similar interbreeding or potentially interbreeding individuals
