  1. Classification History

  2. Classification History • Taxonomy: Branch of biology that groups all life according to their characteristics and history • All life on earth is placed into 1 of 6 kingdoms: • Eubacteria • Archaea • Protista • Fungi • Plantae • Animalia prokaryotes eukaryotes

  3. Carolus Linnaeus • Developed classification system based on physical features • Many rules still used today • Binomial Nomenclature: System of giving every organism 2 names • 1st word: Genus (broad) • 2nd word: Species (specific) • Example: House cat • Genus: Felis (cougars, lions, tigers, cheetahs, etc…) • Species: catus

  4. Binomial Format • When Writing: • Genus capitalized • species lowercase • Underlined entirely Ex: Homo sapiens • When Typing: • Same, except use italics Ex: Homo sapiens Bos taurus

  7. Taxa Kings Play Chess On Fine Gold Stools • 7 individual levels (taxa) used to classify organisms Kingdom (broadest) Phylum Class Order Family Genus Species (specific) • Allows relationships to be clearly seen

  8. Kingdom Phylum Cheetah Classification Class Order Family Genus Species

  9. Kingdom Phylum Red Wolf Classification Class Order Family Genus Species

  10. Kingdom Phylum Class Order Family Human Classification Genus Species

  11. Killer whale classification Kingdom Phylum Class Order Family Genus Species

  12. The more levels in common...the more related the species.

  13. Which two organisms are most related to one another? Killer Whale K = Animals P = Chordata C = Mammals O = Cetacea F = Delphinidae G = Orcinus S = orca Red Wolf K = Animals P = Chordata C = Mammals O = Carnivora F = Canidae G = Canis S = vulpes Polar Bear K = Animals P = Chordata C = Mammals O = Carnivora F = Ursidae G = Ursus S = arctos

  16. Who created the classification system used today? Name the 6 kingdoms of life. Which kingdom(s) are prokaryotic? Which kingdom(s) may be unicellular? Which kingdom(s) are bacteria? Which two taxa make up an organisms binomial name? Place the 7 levels of taxonomy in order from largest to smallest. Name the 7 human taxa, from largest to smallest. Kobe Kuiz
