Chapter 18 Classification

Why Classify? In order to name and group organisms in a logical manner Taxonomy- classifying organisms and assigning each a name

Assigning Scientific Names Early Efforts- described physical characteristics Binomial Nomenclature- (Carolus Linnaeus) two word naming system, the genus and species Always typed in italics Underlined when written

Ursus maritimus Ursus arctos When written or typed the genus is always capitalized and the species is not

Grizzly bear Black bear Giant panda Red fox Abert squirrel Coral snake Sea star KINGDOM Animalia PHYLUM Chordata CLASS Mammalia ORDER Carnivora FAMILY Ursidae GENUS Ursus SPECIES Ursus arctos

Linnaeus’s System (7 levels) Kingdom Phylum Class Order Family Genus Species

Evolutionary Classification Phylogeny- study of evolutionary relationships among organisms Biologists classify organisms by grouping them according to evolutionary descent, not physical characterists.

Cladograms Used derived characteristics to show evolutionary relationships among a group of organisms

Similarities in DNA/RNA
