Assigning Scientific Names To eliminate the confusion of common names, 18 th century scientists

Assigning Scientific Names To eliminate the confusion of common names, 18 th century scientists developed a system to name all organisms in Latin. Binomial Nomenclature: Each species is assigned a two-part scientific name EX: Felis concolor

Scientific Names Written in italics The first word is capitalized It is the organism’s

Scientific Names Written in italics The first word is capitalized It is the organism’s genus Genus: A group of closely related species The second word is lowercased It is the organism’s species Written in Latin

Modern Classification Linnaeus used to group organisms only by their physical characteristics. Using only physical characteristics, how would you classify these organisms?

Modern Classification Now, we use a 3 domain system because of vast differences in different types of bacteria. Current classification system: Domain Kingdom Phylum Class Order Family Genus Species
