Title: Classification History


1
Classification History
2
  • Taxonomy Branch of biology that groups all life
    according to their characteristics and history
  • All life on earth is placed into 1 of 6 kingdoms
  • Bacteria
  • Archaea
  • Protista
  • Fungi
  • Plantae
  • Animalia

Classification History
prokaryotes
eukaryotes
3
Classification is always a work in progress
Where did it all start?
  • Until 1866 only two kingdoms,Animalia and
    Plantae
  • 1866 all single-celled organisms moved to
    kingdom Protista
  • 1938 prokaryotes moved to kingdom Monera
  • 1959 fungi moved to own kingdom
  • 1977 kingdom Monerasplit into kingdoms Bacteria
    and Archaea

4
The 6 kingdoms are classified into domains
  • Domains are above the kingdom level
  • Domain model more clearly shows prokaryotic
    diversity
  • The three domains in the tree of life are
    Bacteria, Archaea, and Eukarya.

From here, we will focus on the kingdoms, but
dont forget about the DOMAINS!

  • Developed classification system based on physical
    features
  • Many rules still used today
  • Binomial Nomenclature System of giving every
    organism 2 names
  • 1st word Genus (broad)
  • 2nd word Species (specific)
  • Example House cat
  • Genus Felis (cougars, lions, tigers, cheetahs,
    etc)
  • Species catus

Binomial Format
  • When Writing
  • Genus Capitalized
  • species lowercase
  • Underlined entirely
  • Ex Homo sapiens
  • When Typing
  • Same, except use italics (instead of underlining)
  • Ex Homo sapiens

  • Defined A group of organisms in a classification
    system.
  • 7 individual levels (taxa) used to classify
    organisms
  • Kingdom (broadest)
  • Phylum
  • Class
  • Order
  • Family
  • Genus
  • Species (specific)
  • Allows relationships to be clearly seen

The more levels in common...the more related the
species.

Review
  • Who created the classification system used today
  • What is it based on?
  • Name the 6 kingdoms of life.
  • Which kingdom(s) are prokaryotic?
  • Which kingdom(s) may be unicellular?
  • Which kingdom(s) are bacteria?
  • Which two taxa make up an organisms binomial
    name?
  • What happened to kingdom Monera?
  • Place the 7 levels of taxonomy in order from
    largest to smallest.
  • Name the 7 human taxa, from largest to smallest.
