Bell Ringer How do we organize the different groups for living things?

ANSWER Kingdom (Kings) Phylum (Play) Class (Cards) Order (On) Family (Fat) Genus (Green) Species (Stools)

Why do we classify? Allows us to keep track of the 3 to 10 million different living things on Earth Classification: The systematic grouping of organisms into categories on the basis of evolutionary relationships or physical appearance The Science of classifying is called “Taxonomy” People have been classifying for nearly 2,000 years

Scientific Naming Carolus Linnaeus Developed systems for naming species and organizing them into groups Named over 4000 plants & animals Used appearance to group species “Father of Taxonomy” Used binomial nomenclature

What is Binomial Nomenclature? “Binomial” = two-name “Nomenclature” = naming system Language: Latin Ex: common house cat – – Felis domesticus – Mountain lion, puma, cougar – Felis concolor – Bobcat – Felis rufus Genusspecies Always capitalizedalways lower-case Both are always italicized Genus and species are the most specific levels of organization

There are 7 levels of classification that describe a species Kingdom Animalia Animalia Animalia Phylum Chordata Chordata Chordata Class Mammalia Mammalia Mammalia Order Carnivora Primate Carnivora Family Ursidae Hominidae Canidae Genus Ursus Homo Canis Species maritimus sapians familiaris ***The more levels of organization that two organisms share, the more closely related the two organisms are!***
