-Although Aristotle developed the first classification system, Linnaeus laid the foundation for modern classification systems by using structural similarities to organize species and by developing a binomial naming system for species-

-Scientists use a two-word naming system called bimoial nomenclature to give species scientific names-

-Classification provides an orderly framework in which to study the relationships among living and extinct species-

-Organisms are classified in a heirarchy of taka: kingdom, phylum or division, class, order, family, genus, species-

17.1 Outline-

How classification began-

  -classification- the grouping of objects based on similarities-

  -taxonomy- the branch of biology that names and groups organisms-

   -taxonomists-

 -Aristotles sytem-

  -developed the 1st widely excepted system of classification-

   -plants-

    -divided into herbs, shrubs, and trees-

   -animals-

   -divided between where they spend the most time, air, land , water-

  -what was wrong with this-

    -birds, bats and flying insects where all together-

 -Linnaeus system-

  -based on physical similarities and not where they are-

 -Two names for a species-

  -binomial nomenclature- 2 word naming system for organisms-

  -first word- genus

  -second word- species

  -uses latin, the international language of science-

 -Biological Classification-

  -taxonomist try to identify the underlying natural relationships of organisms-

 -taxonomy: a framework-

  -taxonomists group organisms together like a skeleton according to similarities-

 -taxonomy: a useful tool-

  -can be used to treat sick humans if the eat a certain plant-

-Taxonomy and the economy-

  -can find something useful for the economy-

 How are living things classified-

  -kingdom-

  -phylum/division-

  -class-

  -order-

  -family-

  -genus-

  -species-

   -go up the line from smallest to biggest-
