5.3 Classification of Biodiversity

5.3 Classification of Biodiversity

1. Nature of Science

   • Cooperation + Collaboration
     • Binomial system
       • Names for species are universal
         • When species are discovered they are given scientific names
           • International-Mindedness
             • International codes of nomenclature and agreements
       • TOK
         • Carolus Linnaeus
           • Racism
             • Is it necessary to consider the social context when evaluating ethical aspects of knowledge claims?
       • Construction of dichotomous key

2. Taxonomists classify species using a hierarchy of taxa

   • All organisms are classified into three domains
     • Eukaryotes
       • Classification
         • One plant + one animal
           • Kingdom
             • Phylum
               • Class
                 • Order
                   • Family
                     • Genus
                       • Species
       • Animals
         • Plants
           • Fungi
             • Protists
           • Bryophyta
           • Filicinophyta
           • Coniferophyta
           • Angiospermophyta
         • Porifera
         • Cnidaria
         • Platylhelmintha
         • Annelida
         • Mollusca
         • Arthropoda
         • Chordata
           • Amphibians
           • Reptiles
           • Mammals
           • Fish
           • Birds
     • Eubacteria
     • Archaea
   • Natural classifications help in identification of species
     • Reclassify groups of species when finding new evidence
   • Allow the prediction of characteristics shared by species within a group
