CLASSIFICATION

In an attempt to understand living things, scientists arrange organisms into groups. Organisms that are biologically similar are grouped together and those that are different are placed in a different group.

Initially, organisms were grouped based on physical similarities. Today, organisms are grouped based on evolutionary relationships/genetic makeup/DNA.

The Three Domains of Life

Kingdom Phylum Class Order Family Genus Species K P C O F G S Organisms are placed into groups called taxa. These taxa are: Kingdom Phylum Class Order Family Genus Species K P C O F G S (Most inclusive) Katy Perry Came Over For Great Spaghetti

What are the six kingdoms of living things? The six kingdoms are: Archaebacteria Eubacteria Protista Fungi Plantae Animalia

Most inclusive Most different 9 million 65,000 5400 270 34 7 Gray wolf 1 Gray wolf

9 million 65,000 5400 270 34 Very similar Wolf(3), coyote(1), jackal(3), dog 7 1 Gray wolf

Most Least similar inclusive 9 million 65,000 5400 270 34 Wolf(3), coyote(1), jackal(3), dog 7 Most similar Least inclusive 1 Gray wolf

Homo sapiens (Two names) Carolus Linnaeus (1707 – 1778) - Develop system of classification/taxa - Developed a two-word naming system to identify organisms called binomial nomenclature. two name Each organism has a scientific name that consists of two names: Homo sapiens (Two names)

Homo sapiens genus species The scientific name must be: First name Second name genus species Homo sapiens capitalized lowercase The scientific name must be: italicized in print and underlined when handwritten.

Examples of Scientific Names Canis means dog Canis familiaris - domestic dog Canis latrans - coyote Canis lupus - gray wolf

Examples of Scientific Names Felis means cat Felis catus - Domestic cat Felis beite - Chinese mountain cat Felis chaus - Jungle cat
