Biologists use classification to organize living things into groups so that the organisms are easier to study. CLASSIFICATION is the process of grouping things based on their similarities. TAXONOMY is the study of how living things are classified. Taxonomy is useful because once an organism is classified, scientists know a lot about the organism.

Carolus Linnaeus Swedish naturalist, 1750’s Binomial Nomenclature First name is Genus Second name is Species Ex: genus Rana has several different species of frogs. Rana catesbiana American bullfrog Rana muscosa Mountain yellow-legged frog Rana pretiosa Oregon spotted frog

In binomial nomenclature, which word is capitalized? Only Genus (first name) is capitalized. How is the name written? In ITALICS when typed, underlined when hand- written. Homo sapiens

Levels of Classification The more classification levels that 2 organisms share, the more characteristics (or DNA) they have in common. Scientists can classify organisms using DNA analysis which can more accurately show relationships among organisms.
