  1. Is your closet organized?

  2. Living things are organized into 6 kingdoms

  3. 6 Kingdoms-{3 domains} • Archaebacteria • Eubacteria • Protists • Fungi • Plants • Animals

  4. Classification • The systematic grouping of organisms into categories on the basis of relationships between them. • Also known as the science of taxonomy.

  5. Why are things classified?Helps us organize information AND communicate with others EXAMPLES of things that we organize: Supermarket aisles Libraries Classes Teams/sports Members of a family Roads Cities Money

  6. Human Taxonomy • HUMANS • Kingdom Animal • Phylum Chordata • Class Mammals • Order Primate • Family Hominadae • Genus Homo • Species Sapien

  7. KPCOFGS • Kind • Professors • Can • Often • Fail • Good • Students

  8. Early history(2,000 ya) • Aristotle grouped everything into simple groups such as animals or plants • He then grouped animals according to if they had blood or didn’t have blood, and if they had live young or laid eggs, and so on…

  9. Taxonomy • Is the science of naming and classifying organisms-has sub-groups and names • Father of taxonomy is Carl Linnaeus (1707-1778)

  10. Binomial nomenclature • C. Linnaeus developed a system that gives a 2 word name to every organism. • The 2 word naming system is called binomial nomenclature • It helps to avoid confusion • It uses the genus and species name only

  11. Red Snakebark Maple Acer capillipes • Paperbark Maple Acer griseum • Japanese Maple Acer palmatum

  12. PantheraComprising the species:Lion, tiger, jaguar, leopard on the basis of cranial features Tiger- Panthera tigris Lion- Panthera leo • Jaguar- Pantheraonca SNOW LEOPARD also belongs to the Panthera-----added 2008

  13. Rules used to write scientific names Homo sapiens • An organism’s genus is always written first; the organism’s species is always written second • The genus is Capitalized; the species is written in lower case • Scientific names of organisms are always italicized or underlined

  14. Some common names • Canis familiaris - dog • Felis domesticus - cat • Canis lupus - wolf • Vulpes vulpes - fox • Ichthyomyzon gagi - brook lamprey • Populus deltoides - cottonwood • Cercis canadensis - red bud • Diospyros virginiana - persimmon • Carya illinoensis - pecan

  15. A dichotomous key • is used to identify organisms that you do not already know. • A reference tool where a series of choices between alternative characters leads progressively to the identification of the species. • Means "two forks".
