• 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

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?

• 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).
• .

• B. Inferring Phylogeny
• ?Infer the probable relationships among
  species
