Explore the history and modern methods of classification and taxonomy in biology, from the early classification systems to the six kingdom system. Learn about binomial nomenclature, evidence used in classification, inferring phylogeny, and the six kingdoms of Archaea, Eubacteria, Protista, Fungi, Plantae, and Animalia.

  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).
