  1. Chapter 17: The Tree of LifeHow Do We Classify Organisms

  2. How do we group the place where the utensils are place? Draw it in the space below • There are 1.9 million different identified species (alive and extinct) • How can we keep all these organisms in order?

  3. Classification • is the method of logically grouping organisms based on some common characteristics • Physical & Structural similarities • Biochemistry– more similar the proteins the more similar the DNA • Evolutionary history

  4. Think of the many words you can use to describe something that is really, really good. Binomial Nomenclature. • Every species is given a two-part scientific name using Latin words • Homo sapiens – that’s us • Canisfamiliaris – domestic dog • Felisdomestica – house cat

  5. 8 Major Levels of Classification Dear King Philip Came Over From Germany Saturday

  6. The Taxonomic order: • From the largest, most inclusive group to the smallest, most exclusive, specific taxa. Taxa Human Grizzly Chimp Domain Eukarya Eukarya Eukarya Kingdom Animalia Animalia Animalia Phylum Chordata Chordata Chordata Class Mammalia Mammalia Mammalia Order Primate Carnivora Primate Family Hominoidae Ursidae Hominoidae Genus Homo Ursus Pan Species sapiens arctos troglodyte Which two organisms are more closely related and why?

  7. The Six Kingdom System

  8. Name their Kingdom

  9. Name the 6 Kingdoms • Eubacteria • Archaebacteria • Protista • Plantae • Animalia • Fungi

  10. CladisticsTakes an evolutionary look into classification Cladogram is an evolutionary tree that hypothesizes how species may be related to each other through common ancestors • Clade • Group of species • Derived Characters • Trait that is common to all the species up the cladogram

  11. Outgroup
