Classification

1
Classification

• A Biological Tool for Organization

2
Classification Not Only for Biology

• How would you classify this music?
• Audioslave Metallica
• Brooks Dunn Kenny Chesney
• Korn Alicia Keys
• Toni Braxton Usher
• Carrie Underwood

3
Musical Classification Questions

• Are there any classifications of music missing?
• Do these classifications have sub classes?
• Why classify music? How does it help buyers,
  sellers and musicians?

4
Biological Classification

• A system of binomial nomenclature (i.e., two
  names) is used to name organisms.
• The first of the two names is the genus and the
  second name is the species.
• Genus and species names are underlined or
  italicized.
• Genus is capitalized, but species is not.

5
The Species

• A group of organisms that have structural,
  functional, and developmental similarities, and
  that are able to interbreed and produce fertile
  offspring.
• The species is the fundamental unit of biological
  classification.

6
Taxonomy

• Organisms are grouped based on their similarities
  into taxonomic groups or taxa. Listed from the
  broadest to the most specific, they are
• Domain/KingdomPhylum (plural
  phyla)ClassOrderFamilyGenus (plural
  genera)Species (singular and plural)

7
There Are Six Kingdoms

• Archaebacteia
• Eubacteria
• Protists
• Fungi
• Plants
• Animals

8
Six kingdoms are grouped into three domains

• Domain Eukarya
• Domain Bacteria
• Domain Archaea

Domain Eukarya

• Organisms with eukaryotic cells (cells with a
  nucleus)
• Kingdom Animalia (animals)
• Kingdom Plantae (plants)
• Kingdom Fungi (mushrooms, fungus)
• Kingdom Protista (single-celled organisms)

11
Domain Bacteria

• Organisms with prokaryotic cells (cells without a
  nucleus)
• Kindgom Eubacteria (bacteria and cyanobacteria or
  blue-green algae)

12
Domain Archaea

• Organisms with prokaryotic cells, but which are
  very unusual and quite different from Bacteria.
  Archaea tend to live under extreme conditions of
  heat, salinity, acidity.
• Kingdom Archaebacteria

13
Dichotomous Key

• An easy way to classify organisms or any kind of
  information
• Uses a series of yes/no questions to get to a
  single description that applies to only one thing
• Classification of all living things is done this
  way
