  1. Classification Original powerpoint created by Kelso Consulting, 2004 Modified and added to by Ms Parker, 2011

  2. What is Classification? • Classification is the arrangement of organisms into orderly groups based on their similar characteristics. • The science of classification which involves identifying, classifying and naming is also known as taxonomy. • taxis = arrangement or order • nomy = law

  3. Classification Groups • Taxon ( taxa-plural) is a category into which related organisms are placed • There is a hierarchy of groups (taxa) from broadest to most specific • Domain, Kingdom, Phylum, Class, Order, Family, Genus, species

  4. Hierarchy-Taxonomic Groups • Domain • Kingdom • Phylum • Class • Order • Family • Genus • Species

  5. Domain Eukarya • Dear • King • Phillip • Came • Over • For • Great • Sushi

  6. KINGDOM PHYLUM – What is in kingdom that is not in phylum? CLASS – What is in Phylum that is not in class? Bird – It does not nurse its young.

  7. After domain each taxon becomes narrower and characteristics become more specific until the final two taxa name the genus and species. • Genus – a group of different organisms that share similar characteristics and are related to each other. It may consist of several closely related species or sometimes only one species. • Species – the smallest taxa that refers to a group of organisms that are able to breed, producing fertile offspring.

  8. Confusion in Using Different Languages for Names

  9. Latin Names are Understood by all Taxonomists

  10. Benefits of Classifying • Accurately & uniformly names organisms • Prevents misnomers such as starfish & jellyfish that aren't really fish • Uses same language (Latin or some Greek) for all names Sea”horse”??

  11. Carolus Linnaeus1707 – 1778 • 18th century • Taxonomist known • as the “Father of • Taxonomy” • Classified • organisms by their • structure,size, shape and color

  12. Carolus Linnaeus • Developed the modern system of naming known as binomial nomenclature • Every organism gets a • Two-word name (Genus & species) • (Like our last and first name in a database.)

  13. Standardized Naming Rules • Binomial nomenclature • uses Genus and species • Latin or Greek • a.Italicize if typed • b.Underline when hand writing • c. Capitalize genus, • d. but NOT species • Canislupis= wolf • Alliumcepia = onion Turdusmigratorius American Robin

  14. Binomial Nomenclature Which of these share the same genus? What is your reasoning?

  15. The scientific name of an organisms is its Genusand Species … • What is the scientific name of these two organisms?

  16. Basis for Modern Taxonomy • Homologous structures (same structure, different function) • Similar embryonic development • Similarity in DNA, RNA, or amino acid sequence of Proteins

  17. Homologous Structures show Similarities in mammals.

  18. Similarities in Vertebrate Embryos
