  1. Taxonomy & Scientific Names pg. 190 - 193

  2. What is Taxonomy? Taxonomy - the science of classifyingall organisms (living AND extinct) • Not to be confusedwith taxidermy...

  3. Classifying everything ever... • How would you classify all life on Earth?

  4. The current system... • Very old (1700s), all ‘names’ in latin • Based on physical/structural features( the more two things look alike, the closer their relationship) • 7 levels of organization

  5. King Paul... • It all starts withKingdom... • There are 5 Kingdoms: • Anamalia • Plantae • Fungi • Protista • Eubacteria • Archaebacteria

  6. Commomtaxonomics… • Every level of classification is more specific • The scientific names that matter most (and are the MOST specific) are the Genus and Species Species – a group of organisms with similar features that can interbreed to make fertile offspring + = mule horse donkey

  7. Name that organism Homo Genus: Species: Abbreviated: Common name: sapiens H. sapiens Human

  8. Name that organism Castor Genus: Species: Abbreviated: Common name: canadensis C. canadensis Beaver

  9. Name that organism Escherichia Genus: Species: Abbreviated: Common name: coli E. coli E. coli

  10. Why I owe taxonomy big time... Genus: Avicularia Species: avicularia Genus: Avicularia Species: urticans Genus: Avicularia Species: avicularia

  11. Dichotomous keys • Ever play 20 questions? • Let’s try! • A dichotomous key is like 20 questions except strictly for organisms

  12. Dichotomous keys cont’d • Two-part answer key • Series of choices must be made • Each choice leads to new branch • End result = name of organisms being identified

  13. Try this... • Classifying Sharks activity
