Title: Classification and Taxonomy


1
Classification and Taxonomy
2
What is Classification?
  • Classification is the arrangement of organisms
    into orderly groups based on their similarities
  • Classification is also known as taxonomy
  • Taxonomists are scientists that identify name
    organisms

3
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

Seahorse??
4
Confusion in Using Different Languages for Names
5
Latin Names are Understood by all Taxonomists
6
Carolus Linnaeus 1707 1778
  • 18th century taxonomist
  • Classified organisms by their structure
  • Developed naming system still used today

7
Carolus Linnaeus
  • Called the Father of Taxonomy
  • Developed the modern system of naming known as
    binomial nomenclature
  • Two-word name (Genus species)

8
Standardized Naming
  • Binomial nomenclature used
  • Genus species
  • Latin or Greek
  • Italicized in print
  • Capitalize genus, but NOT species
  • Underline when writing

Turdus migratorius

10
Rules for Naming Organisms
  • The International Code for Binomial Nomenclature
    contains the rules for naming organisms
  • All names must be approved by International
    Naming Congresses (International Zoological
    Congress)
  • This prevents duplicated names

11
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

Hierarchy-Taxonomic Groups
  • Domain
  • Kingdom
  • Phylum (Division used for plants)
  • Class
  • Order
  • Family

  • Genus
  • Species
