1 Classification Chapter 18

2 Finding Order in Diversity
Taxonomy: classify organisms and assign each organism a universally accepted name Binomial Nomenclature: each species is assigned a two-part scientific name Always written in italics

3 Linnaeus’s System of Classification
Hierarchical system of classification includes seven levels: (page 450) Species Genus Family Order Class Phylum kingdom

5 Evolutionary Classification
Phylogeny: evolutionary relationships among orgnaisms Appendages Conical Shells Crab Barnacle Limpet CLASSIFICATION BASED ON VISIBLE SIMILARITIES

6 Kingdoms and Domains 6 kingdom classification system: Eubacteria
Archaebacteria Protist Fungi Plantae Animalia

7 Three Domain System Eukarya: protist, fungi, plants, animals
Bacteria: Eubacteria Archaea: Archeabacteria

8 DOMAIN ARCHAEA DOMAIN EUKARYA DOMAIN BACTERIA
