  2. Classification is the grouping of things according to their similarities, or how they are alike.

  3. The science of classifying living things is called taxonomy.Scientists who classify living things are taxonomists.

  4. Taxonomists use many different features of living things to classify them.shared physical characteristicscell structurerelationships between organismsgenetic similarities

  5. Why classify?Classifying living things makes it easier for scientists to investigate and answer important questions about the many organisms of the world.

  6. How are living things classified?

  7. Organisms are classified into a series of seven groups. • Kingdom • Phylum • Class • Order • Family • Genus • Species

  8. The largest classification group is the kingdom. There are six kingdoms of living things. Animals Plants Fungi Protists Archaebacteria Eubacteria

  9. Each kingdom is subdivided into smaller groups called phyla. And each phylum is subdivided into smaller classes.

  10. Each class is subdivided into even smaller groups called orders. And each order is subdivided into smaller families.

  11. Each family is subdivided into smaller groups called genera. And finally, each genus is subdivided into species.

  12. A species is the smallest classification group.

  13. Can you list the seven classification groups from largest to smallest?

  14. Try this mnemonicdevice: King Phillip chooses onions for good soup.

  15. Where did taxonomy begin?

  16. Carolus Linnaeus Carolus Linnaeus was a Swedish physician and botanist who lived in the 1700’s. He founded the science of taxonomy or our modern classification system.

  17. Giving organisms names. Linnaeus developed a system of scientific naming for organisms. This system is called binomial nomenclature.

  18. The scientific name of an organism consists of two Latin words. The first word of the name is the organism’s genus and the second word of the name is its species.

  19. Examples of Organismsand their scientific names. • Elephasmaximus - the Indian elephant • Tyrannosaurusrex - the tyrant lizard • Mephitismephitis - the skunk • Homosapiens - humans • Canisfamiliaris - the dog • Canislupus - the wolf • Felisdomestica - the house cat
