2. Classification

3. I History of Taxonomy A. Science of grouping organisms according to their presumed natural relationships.  Started more than 2000 years ago with Aristotle classified things either as plant of animal.  Worked until the 18th century. Did not accommodate all the variations of living organisms.  Used common names (robin or fir tree). May not describe the organisms accurately (Jellyfish)

4. B. Binomial Nomenclature  Linnaeus (1707 - 1778) developed a system of grouping organisms into a hierarchical categories.  Two names for all living organisms (scientific names)  Levels of Classification  Kingdom, Phylum, Class, Order, Family, Genus, Species

5. Levels of Classification

6. Review  List the levels of classifications from largest to smallest.  How long ago did classification start of living things?  Who is the father of classification?

7. II Modern Taxonomy A. Evidence Used in Classification  Comparative morphology (Similarities in structures).  Dichotomous Key specialized book that is used to aid in identification.  Embryology (wings of a birds & insect, different tissues in each embryo) & Chromosomes (determine how closely related two organisms are)..

8. B. Inferring Phylogeny  Infer the probable relationships among species

9. Cladogram

10. Review  Why don’t we use common names to scientifically describe an organism?  What is the purpose of a phylogenic tree or cladiogram?

16. III Six Kingdom System A. Archae – Harsh Environments

17. B. Eubacteria  Prokaryotic organisms. Lack a nuclei & other membrane bond organelles.  Live in all environments  Absorb nutrients or autotrophs  5,000 identified species, but have the greatest population of species (Bacteria).  Unicellular

18. C. Protista  Eukaryotic organisms. Have a nucleus & other membrane bond organelles.  Unicellular or multicellular.  Live in aquatic environments.  Reproduce sexually or asexually.  50,000 species (Algae & Protozoa).  Some are autotroph & heterotrophs.  Multicellular

19. D. Fungi  Eukaryotic organisms.  Absorb nutrients.  Terrestrial.  Reproduce sexually or asexually.  100,000 species (mushrooms, puffballs, & bread molds).  Multicellular.

20. E. Plantae  Eukaryotic organisms  Autotrophs.  Most are terrestrial.  Reproduce sexually or asexually.  Multicellular.  350,000 species (mosses, ferns, conifers, & flowering plants).  Multicellular.

21. F. Animalia  Eukaryotic organisms.  Heterotrophs.  Multicellular.  Reproduce sexually or asexually.  Terrestrial & aquatic  More than a million ( spiders to whales).
