Classification

Finding Order in Diversity Taxonomy: classifying system for organisms binomial nomenclature: 2-part scientific name 1st: genus; 2nd: species Ursus arctos – grizzly bear

Linnaeus’s Classification System From largest to smallest: Kingdom Phylum Class Order Family Genus Species

Modern Evolutionary Classification Phylogeny: lines of evolutionary descent Similarities in DNA Cladogram: diagram showing the evolutionary relationship between organisms

The Six Kingdoms Eubacteria Archaebacteria Protista Fungi Plantae Animalia.

The Three Domains Eukarya - protists, fungi, plants, and animals Eukaryotes Bacteria - Eubacteria Archaea – Archaebacteria live in extreme environments
