All living things are divided into 6 kingdoms.
Each of those kingdoms is then divided into
phylums, each phylum is divided into classes, etc.
See Table 1 pg. 98

Binomial Nomenclature

• A two part scientific name
• First part is genus
• Last part is species
• (this is kind of backwards if you compare it to
  our names!!)
• Common first part demonstrates relatedness
• Grizzly bear - Ursus horribilis,
• Polar bear - Ursus maritimus
• Koala bear - Phascolarctos cinereus
• Panda bear - Ailuropoda melanoleuca

Kingdoms
Whats wrong with this picture?
8
Should be...6 kingdoms!
Phylogeny

• The evolution of the kingdoms
• Simplest came first then possibly merged into
  more complex organisms

9
Kingdoms
See Table 2 pg. 99

• Listed in order of complexity
• Reproduction - change from asexual to sexual
• Cell structure - increase from single celled to
  multicelled
• Lifestyle - plant-like vs. animal like (autotroph
  vs. heterotroph, cell wall vs none), aquatic vs.
  terrestrial
