Applying the Linnaean System

3:03 Linnaean Classification System
Spec 4.6.4
Previous Binomial Naming System Next Development of Classification
  • For the exam, understanding the Linnaean system is required.
  • Example given: classification of a red fox, known as Veers.
  • Instructions include completing a partially filled table with classification details.
  • Step one involves reading the table and identifying the command word, which is "complete."
  • "Complete" means to add missing information to the table.
  • The table has classification groups on the left and corresponding names on the right.
  • Step two involves using a mnemonic ("King penguins climb over frozen grassy slopes") to remember classification groups.
  • Step three links the mnemonic to the groups, filling in the missing classifications such as class, order, family, and species.
  • Step four completes the table using the mnemonic.
  • Additional application of the Linnaean system includes comparing the red fox to other animals to determine closest relations.
  • By comparing classification groups, it is determined that the lion, being in the same order (Carnivore), is more closely related to the red fox than humans, who are in the order Primates.
  • In an exam setting, the answer would state that the lion is most closely related to the red fox due to their shared order.
