   What criteria did you use
   to group your organisms?

Could you break any of your
groups down into
sub-groups?




                               4
    Species of Organisms

•There are 13 billion known
 species of organisms
•This is only 5% of all
 organisms that ever lived!!!!!
•New organisms are still being
 found and identified



                                  5
 If only 5% of organisms that
 ever lived are still alive, what
 happened to the other 95%?

                   Turn to your
                   table partners
and discuss what you think
happened to the other 95% and
why do you think it happened.
                                    6
   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


                                  7
    Benefits of Classifying

•organisms & uniformly names
 Accurately

•starfish &misnomers that aren't
 Prevents
            jellyfish
                      such as
 really fish
•Uses same language (Latin or
 some Greek) for all names
              Sea”horse”??

Confusion in Using Different
   Languages for Names




                               9
Latin Names are Understood by
        all Taxonomists




                                10
    Early Taxonomists
•2000 years ago,
Aristotle was the
first taxonomist
• Aristotle divided
organisms into
plants & animals
• He subdivided
them by their
habitat ---land,
sea, or air dwellers
                        11
       Carolus Linnaeus
              1707 – 1778

• 18th century
  taxonomist
• Classified
    organisms by
    their structure
•   Developed
    naming system
    still used
    today

                            12
    Carolus Linnaeus
•Called the “Father of
 Taxonomy”
•Developed the modern
 system of naming known
 as binomial nomenclature
•Two-word name (Genus &
 species)

Answer the following prompt
beginning with yes but . . .


 We have discussed many
 different benefits of
 classifying organisms . . .

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

      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
