About This Quiz & Worksheet

This quiz and worksheet contains multiple-choice questions you can answer any time to see how well you understand classification systems. Just a few of the topics covered in these questions include what phylogeny and morphology mean and the scientifically objective system of classification that only takes into account shared traits from a shared evolutionary ancestor.

Quiz & Worksheet Goals

Use this quiz to check your knowledge of:

  • Where the system of classifying things based first on broad categories and then into more specific categories originated
  • The definitions of morphology and phylogeny
  • Potential issues with phenetics
  • What it means in cladistics if two organisms are closely related

Skills Practiced

  • Information recall - access the knowledge you've gained regarding what can potentially occur when using phenetics
  • Reading comprehension - ensure that you draw the most important information from the related lesson on classification systems
  • Knowledge application - use your knowledge to answer questions about what it means in cladistics if two organisms are closely related
